The version of Siemens SINEC NMS installed on the remote host is prior to 2.0.1.0. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA-943925 advisory.

  - coreruleset (aka OWASP ModSecurity Core Rule Set) through 3.3.4 does not detect multiple Content-Type     request headers on some platforms. This might allow attackers to bypass a WAF with a crafted payload,     aka Content-Type confusion between the WAF and the backend application. This occurs when the web     application relies on only the last Content-Type header. Other platforms may reject the additional     Content-Type header or merge conflicting headers, leading to detection as a malformed header.
    (CVE-2023-38199)

  - Some mod_proxy configurations on Apache HTTP Server versions 2.4.0 through 2.4.55 allow a HTTP Request     Smuggling attack. Configurations are affected when mod_proxy is enabled along with some form of     RewriteRule or ProxyPassMatch in which a non-specific pattern matches some portion of the user-supplied     request-target (URL) data and is then re-inserted into the proxied request-target using variable     substitution. For example, something like: RewriteEngine on RewriteRule ^/here/(.*)     http://example.com:8080/elsewhere?$1; [P] ProxyPassReverse /here/ http://example.com:8080/ Request     splitting/smuggling could result in bypass of access controls in the proxy server, proxying unintended     URLs to existing origin servers, and cache poisoning. Users are recommended to update to at least version     2.4.56 of Apache HTTP Server. (CVE-2023-25690)

  - The use of `Module._load()` can bypass the policy mechanism and require modules outside of the policy.json     definition for a given module.

The version of curl installed on the remote host is prior to 8.1.0. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2023-137-01 advisory.

  - A use after free vulnerability exists in curl <v8.1.0 in the way libcurl offers a feature to verify an SSH     server's public key using a SHA 256 hash. When this check fails, libcurl would free the memory for the     fingerprint before it returns an error message containing the (now freed) hash. This flaw risks inserting     sensitive heap-based data into the error message that might be shown to users or otherwise get leaked and     revealed. (CVE-2023-28319)

  - A denial of service vulnerability exists in curl <v8.1.0 in the way libcurl provides several different     backends for resolving host names, selected at build time. If it is built to use the synchronous resolver,     it allows name resolves to time-out slow operations using `alarm()` and `siglongjmp()`. When doing this,     libcurl used a global buffer that was not mutex protected and a multi-threaded application might therefore     crash or otherwise misbehave. (CVE-2023-28320)

  - An improper certificate validation vulnerability exists in curl <v8.1.0 in the way it supports matching of     wildcard patterns when listed as Subject Alternative Name in TLS server certificates. curl can be built     to use its own name matching function for TLS rather than one provided by a TLS library. This private     wildcard matching function would match IDN (International Domain Name) hosts incorrectly and could as a     result accept patterns that otherwise should mismatch. IDN hostnames are converted to puny code before     used for certificate checks. Puny coded names always start with `xn--` and should not be allowed to     pattern match, but the wildcard check in curl could still check for `x*`, which would match even though     the IDN name most likely contained nothing even resembling an `x`. (CVE-2023-28321)

  - An information disclosure vulnerability exists in curl <v8.1.0 when doing HTTP(S) transfers, libcurl might     erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send, even when the     `CURLOPT_POSTFIELDS` option has been set, if the same handle previously wasused to issue a `PUT` request     which used that callback. This flaw may surprise the application and cause it to misbehave and either send     off the wrong data or use memory after free or similar in the second transfer. The problem exists in the     logic for a reused handle when it is (expected to be) changed from a PUT to a POST. (CVE-2023-28322)

The remote host is running a version of macOS / Mac OS X that is 12.x prior to 12.6.8. It is, therefore, affected by multiple vulnerabilities:

  - A privacy issue was addressed with improved private data redaction for log entries. This issue is fixed in     macOS Big Sur 11.7.9, iOS 15.7.8 and iPadOS 15.7.8, macOS Monterey 12.6.8. An app may be able to read     sensitive location information. (CVE-2023-40442)

  - The issue was addressed with improved memory handling. This issue is fixed in watchOS 9.6, macOS Monterey     12.6.8, iOS 15.7.8 and iPadOS 15.7.8, macOS Big Sur 11.7.9, iOS 16.6 and iPadOS 16.6, macOS Ventura 13.5.
    An app may be able to execute arbitrary code with kernel privileges. (CVE-2023-34425)

  - A logic issue was addressed with improved restrictions. This issue is fixed in macOS Ventura 13.5. A     sandboxed process may be able to circumvent sandbox restrictions. (CVE-2023-32364)

  - OpenPrinting CUPS is a standards-based, open source printing system for Linux and other Unix-like     operating systems. Starting in version 2.0.0 and prior to version 2.4.6, CUPS logs data of free memory to     the logging service AFTER the connection has been closed, when it should have logged the data right     before. This is a use-after-free bug that impacts the entire cupsd process. The exact cause of this issue     is the function `httpClose(con->http)` being called in `scheduler/client.c`. The problem is that httpClose     always, provided its argument is not null, frees the pointer at the end of the call, only for     cupsdLogClient to pass the pointer to httpGetHostname. This issue happens in function `cupsdAcceptClient`     if LogLevel is warn or higher and in two scenarios: there is a double-lookup for the IP Address     (HostNameLookups Double is set in `cupsd.conf`) which fails to resolve, or if CUPS is compiled with TCP     wrappers and the connection is refused by rules from `/etc/hosts.allow` and `/etc/hosts.deny`. Version     2.4.6 has a patch for this issue. (CVE-2023-34241)

    Integer overflow vulnerability in tool_operate.c in curl 7.65.2 via crafted value as the retry delay.
    (CVE-2020-19909)

    libcurl offers a feature to verify an SSH server's public key using a SHA 256 hash. When this check fails,     libcurl would free the memory for the fingerprint before it returns an error message containing the (now     freed) hash.

    This flaw risks inserting sensitive heap-based data into the error message that might be shown to users or     otherwise get leaked and revealed. (CVE-2023-28319)

    curl supports matching of wildcard patterns when listed as Subject Alternative Name in TLS server     certificates. curl can be built to use its own name matching function for TLS rather than one provided by     a TLS library.

    This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use     memory after free or similar in the second transfer.

    The problem exists in the logic for a reused handle when it is (expected to be) changed from a PUT to a     POST. (CVE-2023-28322)

Puny coded names always start with `xn--` and should not be allowed to     pattern match, but the wildcard check in curl could still check for `x*`, which would match even though     the IDN name most likely contained nothing even resembling an `x`.


    CVE-2023-28320:
    A denial of service vulnerability exists in curl <v8.1.0 in the way libcurl provides several different     backends for resolving host names, selected at build time. If it is built to use the synchronous resolver,     it allows name resolves to time-out slow operations using `alarm()` and `siglongjmp()`. When doing this,     libcurl used a global buffer that was not mutex protected and a multi-threaded application might therefore     crash or otherwise misbehave.

    CVE-2023-28319:
    A use after free vulnerability exists in curl <v8.1.0 in the way libcurl offers a feature to verify an SSH     server's public key using a SHA 256 hash. When this check fails, libcurl would free the memory for the     fingerprint before it returns an error message containing the (now freed) hash. This flaw risks inserting     sensitive heap-based data into the error message that might be shown to users or otherwise get leaked and     revealed.

    CVE-2023-27538:
    An authentication bypass vulnerability exists in libcurl prior to v8.0.0 where it reuses a previously     established SSH connection despite the fact that an SSH option was modified, which should have prevented     reuse. libcurl maintains a pool of previously used connections to reuse them for subsequent transfers if     the configurations match. However, two SSH settings were omitted from the configuration check, allowing     them to match easily, potentially leading to the reuse of an inappropriate connection.

    CVE-2023-27536:
    An authentication bypass vulnerability exists libcurl <8.0.0 in the connection reuse feature which can     reuse previously established connections with incorrect user permissions due to a failure to check for     changes in the CURLOPT_GSSAPI_DELEGATION option. This vulnerability affects krb5/kerberos/negotiate/GSSAPI     transfers and could potentially result in unauthorized access to sensitive information. The safest option     is to not reuse connections if the CURLOPT_GSSAPI_DELEGATION option has been changed.

    CVE-2023-27535:
    An authentication bypass vulnerability exists in libcurl <8.0.0 in the FTP connection reuse feature that     can result in wrong credentials being used during subsequent transfers. Previously created connections are     kept in a connection pool for reuse if they match the current setup. However, certain FTP settings such as     CURLOPT_FTP_ACCOUNT, CURLOPT_FTP_ALTERNATIVE_TO_USER, CURLOPT_FTP_SSL_CCC, and CURLOPT_USE_SSL were not     included in the configuration match checks, causing them to match too easily. This could lead to libcurl     using the wrong credentials when performing a transfer, potentially allowing unauthorized access to     sensitive information.

    CVE-2023-27534:
    A path traversal vulnerability exists in curl <8.0.0 SFTP implementation causes the tilde (~) character to     be wrongly replaced when used as a prefix in the first path element, in addition to its intended use as     the first element to indicate a path relative to the user's home directory. Attackers can exploit this     flaw to bypass filtering or execute arbitrary code by crafting a path like /~2/foo while accessing a     server with a specific user.


    CVE-2023-27533:
    A vulnerability in input validation exists in curl <8.0 during communication using the TELNET protocol may     allow an attacker to pass on maliciously crafted user name and telnet options during server negotiation.
    The lack of proper input scrubbing allows an attacker to send content or perform option negotiation     without the application's intent. This vulnerability could be exploited if an application allows user     input, thereby enabling attackers to execute arbitrary code on the system.


    CVE-2023-23916:
    An allocation of resources without limits or throttling vulnerability exists in curl <v7.88.0 based on the     chained HTTP compression algorithms, meaning that a server response can be compressed multiple times and     potentially with differentalgorithms. The number of acceptable links in this decompression chain     wascapped, but the cap was implemented on a per-header basis allowing a maliciousserver to insert a     virtually unlimited number of compression steps simply byusing many headers. The use of such a     decompression chain could result in a malloc bomb, making curl end up spending enormous amounts of     allocated heap memory, or trying to and returning out of memory errors.


    CVE-2023-23915:
    A cleartext transmission of sensitive information vulnerability exists in curl <v7.88.0 that could cause     HSTS functionality to behave incorrectly when multiple URLs are requested in parallel. Using its HSTS     support, curl can be instructed to use HTTPS instead of using an insecure clear-text HTTP step even when     HTTP is provided in the URL. This HSTS mechanism would however surprisingly fail when multiple transfers     are done in parallel as the HSTS cache file gets overwritten by the most recentlycompleted transfer. A     later HTTP-only transfer to the earlier host name would then *not* get upgraded properly to HSTS.


    CVE-2023-23914:
    A cleartext transmission of sensitive information vulnerability exists in curl <v7.88.0 that could cause     HSTS functionality fail when multiple URLs are requested serially. Using its HSTS support, curl can be     instructed to use HTTPS instead of usingan insecure clear-text HTTP step even when HTTP is provided in the     URL. ThisHSTS mechanism would however surprisingly be ignored by subsequent transferswhen done on the same     command line because the state would not be properlycarried on.

    CVE-2022-43552:
    A use after free vulnerability exists in curl <7.87.0. Curl can be asked to *tunnel* virtually all     protocols it supports through an HTTP proxy. HTTP proxies can (and often do) deny such tunnel operations.
    When getting denied to tunnel the specific protocols SMB or TELNET, curl would use a heap-allocated struct     after it had been freed, in its transfer shutdown code path.


    CVE-2022-43551:
    A vulnerability exists in curl <7.87.0 HSTS check that could be bypassed to trick it to keep using HTTP.
    Using its HSTS support, curl can be instructed to use HTTPS instead of using an insecure clear-text HTTP     step even when HTTP is provided in the URL. However, the HSTS mechanism could be bypassed if the host name     in the given URL first uses IDN characters that get replaced to ASCII counterparts as part of the IDN     conversion. Like using the character UTF-8 U+3002 (IDEOGRAPHIC FULL STOP) instead of the common ASCII full     stop (U+002E) `.`. Then in a subsequent request, it does not detect the HSTS state and makes a clear text     transfer. Because it would store the info IDN encoded but look for it IDN decoded.


    CVE-2022-42916:
    In curl before 7.86.0, the HSTS check could be bypassed to trick it into staying with HTTP. Using its HSTS     support, curl can be instructed to use HTTPS directly (instead of using an insecure cleartext HTTP step)     even when HTTP is provided in the URL. This mechanism could be bypassed if the host name in the given URL     uses IDN characters that get replaced with ASCII counterparts as part of the IDN conversion, e.g., using     the character UTF-8 U+3002 (IDEOGRAPHIC FULL STOP) instead of the common ASCII full stop of U+002E (.).
    The earliest affected version is 7.77.0 2021-05-26.


    CVE-2022-42915:
    curl before 7.86.0 has a double free. If curl is told to use an HTTP proxy for a transfer with a non-     HTTP(S) URL, it sets up the connection to the remote server by issuing a CONNECT request to the proxy, and     then tunnels the rest of the protocol through. An HTTP proxy might refuse this request (HTTP proxies often     only allow outgoing connections to specific port numbers, like 443 for HTTPS) and instead return a non-200     status code to the client. Due to flaws in the error/cleanup handling, this could trigger a double free in     curl if one of the following schemes were used in the URL for the transfer: dict, gopher, gophers, ldap,     ldaps, rtmp, rtmps, or telnet. The earliest affected version is 7.77.0.


    CVE-2022-35252:
    When curl is used to retrieve and parse cookies from a HTTP(S) server, itaccepts cookies using control     codes that when later are sent back to a HTTPserver might make the server return 400 responses.
    Effectively allowing asister site to deny service to all siblings.

    CVE-2022-32221:
    When doing HTTP(S) transfers, libcurl might erroneously use the read callback (`CURLOPT_READFUNCTION`) to     ask for data to send, even when the `CURLOPT_POSTFIELDS` option has been set, if the same handle     previously was used to issue a `PUT` request which used that callback. This flaw may surprise the     application and cause it to misbehave and either send off the wrong data or use memory after free or     similar in the subsequent `POST` request. The problem exists in the logic for a reused handle when it is     changed from a PUT to a POST.

    CVE-2022-32208:
    When curl < 7.84.0 does FTP transfers secured by krb5, it handles message verification failures wrongly.
    This flaw makes it possible for a Man-In-The-Middle attack to go unnoticed and even allows it to inject     data to the client.

    CVE-2022-32207:
    When curl < 7.84.0 saves cookies, alt-svc and hsts data to local files, it makes the operation atomic by     finalizing the operation with a rename from a temporary name to the final target file name.In that rename     operation, it might accidentally *widen* the permissions for the target file, leaving the updated file     accessible to more users than intended.

    CVE-2022-32206:
    curl < 7.84.0 supports chained HTTP compression algorithms, meaning that a serverresponse can be     compressed multiple times and potentially with different algorithms. The number of acceptable links in     this decompression chain was unbounded, allowing a malicious server to insert a virtually unlimited     number of compression steps.The use of such a decompression chain could result in a malloc bomb,     makingcurl end up spending enormous amounts of allocated heap memory, or trying toand returning out of     memory errors.

    CVE-2022-32205:
    A malicious server can serve excessive amounts of `Set-Cookie:` headers in a HTTP response to curl and     curl < 7.84.0 stores all of them. A sufficiently large amount of (big) cookies make subsequent HTTP     requests to this, or other servers to which the cookies match, create requests that become larger than the     threshold that curl uses internally to avoid sending crazy large requests (1048576 bytes) and instead     returns an error.This denial state might remain for as long as the same cookies are kept, match and     haven't expired. Due to cookie matching rules, a server on `foo.example.com` can set cookies that also     would match for `bar.example.com`, making it it possible for a sister server to effectively cause a     denial of service for a sibling site on the same second level domain using this method.


    CVE-2023-38545:
    This flaw makes curl overflow a heap based buffer in the SOCKS5 proxy     handshake.

    When curl is asked to pass along the host name to the SOCKS5 proxy to allow     that to resolve the address instead of it getting done by curl itself, the     maximum length that host name can be is 255 bytes.

    If the host name is detected to be longer, curl switches to local name     resolving and instead passes on the resolved address only. Due to this bug,     the local variable that means let the host resolve the name could get the     wrong value during a slow SOCKS5 handshake, and contrary to the intention,     copy the too long host name to the target buffer instead of copying just the     resolved address there.

    The target buffer being a heap based buffer, and the host name coming from the     URL that curl has been told to operate with.


    CVE-2023-38546:
    This flaw allows an attacker to insert cookies at will into a running program     using libcurl, if the specific series of conditions are met.

    libcurl performs transfers. In its API, an application creates easy handles     that are the individual handles for single transfers.

    libcurl provides a function call that duplicates en easy handle called     [curl_easy_duphandle](https://curl.se/libcurl/c/curl_easy_duphandle.html).

    If a transfer has cookies enabled when the handle is duplicated, the     cookie-enable state is also cloned - but without cloning the actual     cookies. If the source handle did not read any cookies from a specific file on     disk, the cloned version of the handle would instead store the file name as     `none` (using the four ASCII letters, no quotes).

    Subsequent use of the cloned handle that does not explicitly set a source to     load cookies from would then inadvertently load cookies from a file named     `none` - if such a file exists and is readable in the current directory of the     program using libcurl. And if using the correct file format of course.
