The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2024:1627-1 advisory.

  - Faulty input validation in the core of Apache allows malicious or exploitable backend/content generators     to split HTTP responses. This issue affects Apache HTTP Server: through 2.4.58. (CVE-2023-38709)

  - HTTP Response splitting in multiple modules in Apache HTTP Server allows an attacker that can inject     malicious response headers into backend applications to cause an HTTP desynchronization attack. Users are     recommended to upgrade to version 2.4.59, which fixes this issue. (CVE-2024-24795)

  - HTTP/2 incoming headers exceeding the limit are temporarily buffered in nghttp2 in order to generate an     informative HTTP 413 response. If a client does not stop sending headers, this leads to memory exhaustion.
    (CVE-2024-27316)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - httpd: mod_proxy: X-Forwarded-For dropped by hop-by-hop mechanism (CVE-2022-31813)

  - Apache HTTP Server versions 2.4.6 to 2.4.46 mod_proxy_wstunnel configured on an URL that is not     necessarily Upgraded by the origin server was tunneling the whole connection regardless, thus allowing for     subsequent requests on the same connection to pass through with no HTTP validation, authentication or     authorization possibly configured. (CVE-2019-17567)

  - Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in     mod_auth_digest. There is no report of this overflow being exploitable, nor the Apache HTTP Server team     could create one, though some particular compiler and/or compilation option might make it possible, with     limited consequences anyway due to the size (a single byte) and the value (zero byte) of the overflow     (CVE-2020-35452)

  - Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Cookie header handled by mod_session can     cause a NULL pointer dereference and crash, leading to a possible Denial Of Service (CVE-2021-26690)

  - Apache HTTP Server versions 2.4.39 to 2.4.46 Unexpected matching behavior with 'MergeSlashes OFF'     (CVE-2021-30641)

  - A crafted method sent through HTTP/2 will bypass validation and be forwarded by mod_proxy, which can lead     to request splitting or cache poisoning. This issue affects Apache HTTP Server 2.4.17 to 2.4.48.
    (CVE-2021-33193)

  - A carefully crafted request uri-path can cause mod_proxy_uwsgi to read above the allocated memory and     crash (DoS). This issue affects Apache HTTP Server versions 2.4.30 to 2.4.48 (inclusive). (CVE-2021-36160)

  - A carefully crafted request body can cause a read to a random memory area which could cause the process to     crash. This issue affects Apache HTTP Server 2.4.52 and earlier. (CVE-2022-22719)

  - If LimitXMLRequestBody is set to allow request bodies larger than 350MB (defaults to 1M) on 32 bit systems     an integer overflow happens which later causes out of bounds writes. This issue affects Apache HTTP Server     2.4.52 and earlier. (CVE-2022-22721)

  - Out-of-bounds Write vulnerability in mod_sed of Apache HTTP Server allows an attacker to overwrite heap     memory with possibly attacker provided data. This issue affects Apache HTTP Server 2.4 version 2.4.52 and     prior versions. (CVE-2022-23943)

  - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of     Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This     issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.53 and prior versions.
    (CVE-2022-26377)

  - The ap_rwrite() function in Apache HTTP Server 2.4.53 and earlier may read unintended memory if an     attacker can cause the server to reflect very large input using ap_rwrite() or ap_rputs(), such as with     mod_luas r:puts() function. Modules compiled and distributed separately from Apache HTTP Server that use     the 'ap_rputs' function and may pass it a very large (INT_MAX or larger) string must be compiled against     current headers to resolve the issue. (CVE-2022-28614)

  - Apache HTTP Server 2.4.53 and earlier may crash or disclose information due to a read beyond bounds in     ap_strcmp_match() when provided with an extremely large input buffer. While no code distributed with the     server can be coerced into such a call, third-party modules or lua scripts that use ap_strcmp_match() may     hypothetically be affected. (CVE-2022-28615)

  - In Apache HTTP Server 2.4.53 and earlier, a malicious request to a lua script that calls r:parsebody(0)     may cause a denial of service due to no default limit on possible input size. (CVE-2022-29404)

  - If Apache HTTP Server 2.4.53 is configured to do transformations with mod_sed in contexts where the input     to mod_sed may be very large, mod_sed may make excessively large memory allocations and trigger an abort.
    (CVE-2022-30522)

  - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of     Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This     issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.54 and prior versions.
    (CVE-2022-36760)

  - Prior to Apache HTTP Server 2.4.55, a malicious backend can cause the response headers to be truncated     early, resulting in some headers being incorporated into the response body. If the later headers have any     security purpose, they will not be interpreted by the client. (CVE-2022-37436)

  - HTTP Response Smuggling vulnerability in Apache HTTP Server via mod_proxy_uwsgi. This issue affects Apache     HTTP Server: from 2.4.30 through 2.4.55. Special characters in the origin response header can     truncate/split the response forwarded to the client. (CVE-2023-27522)

  - Out-of-bounds Read vulnerability in mod_macro of Apache HTTP Server.This issue affects Apache HTTP Server:
    through 2.4.57. (CVE-2023-31122)

  - Faulty input validation in the core of Apache allows malicious or exploitable backend/content generators     to split HTTP responses. This issue affects Apache HTTP Server: through 2.4.58. (CVE-2023-38709)

  - HTTP Response splitting in multiple modules in Apache HTTP Server allows an attacker that can inject     malicious response headers into backend applications to cause an HTTP desynchronization attack. Users are     recommended to upgrade to version 2.4.59, which fixes this issue. (CVE-2024-24795)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - httpd: mod_proxy: X-Forwarded-For dropped by hop-by-hop mechanism (CVE-2022-31813)

  - In Apache httpd 2.0.23 to 2.0.65, 2.2.0 to 2.2.34, and 2.4.0 to 2.4.29, mod_authnz_ldap, if configured     with AuthLDAPCharsetConfig, uses the Accept-Language header value to lookup the right charset encoding     when verifying the user's credentials. If the header value is not present in the charset conversion table,     a fallback mechanism is used to truncate it to a two characters value to allow a quick retry (for example,     'en-US' is truncated to 'en'). A header value of less than two characters forces an out of bound write of     one NUL byte to a memory location that is not part of the string. In the worst case, quite unlikely, the     process would crash which could be used as a Denial of Service attack. In the more likely case, this     memory is already reserved for future use and the issue has no effect at all. (CVE-2017-15710)

  - In Apache httpd 2.4.0 to 2.4.29, the expression specified in <FilesMatch> could match '$' to a newline     character in a malicious filename, rather than matching only the end of the filename. This could be     exploited in environments where uploads of some files are are externally blocked, but only by matching the     trailing portion of the filename. (CVE-2017-15715)

  - A specially crafted request could have crashed the Apache HTTP Server prior to version 2.4.30, due to an     out of bound access after a size limit is reached by reading the HTTP header. This vulnerability is     considered very hard if not impossible to trigger in non-debug mode (both log and build level), so it is     classified as low risk for common server usage. (CVE-2018-1301)

  - A specially crafted HTTP request header could have crashed the Apache HTTP Server prior to version 2.4.30     due to an out of bound read while preparing data to be cached in shared memory. It could be used as a     Denial of Service attack against users of mod_cache_socache. The vulnerability is considered as low risk     since mod_cache_socache is not widely used, mod_cache_disk is not concerned by this vulnerability.
    (CVE-2018-1303)

  - In Apache httpd 2.2.0 to 2.4.29, when generating an HTTP Digest authentication challenge, the nonce sent     to prevent reply attacks was not correctly generated using a pseudo-random seed. In a cluster of servers     using a common Digest authentication configuration, HTTP requests could be replayed across servers by an     attacker without detection. (CVE-2018-1312)

  - In Apache HTTP Server 2.4 release 2.4.38 and prior, a race condition in mod_auth_digest when running in a     threaded server could allow a user with valid credentials to authenticate using another username,     bypassing configured access control restrictions. (CVE-2019-0217)

  - A vulnerability was found in Apache HTTP Server 2.4.0 to 2.4.38. When the path component of a request URL     contains multiple consecutive slashes ('/'), directives such as LocationMatch and RewriteRule must account     for duplicates in regular expressions while other aspects of the servers processing will implicitly     collapse them. (CVE-2019-0220)

  - In Apache HTTP Server 2.4.0-2.4.39, a limited cross-site scripting issue was reported affecting the     mod_proxy error page. An attacker could cause the link on the error page to be malformed and instead point     to a page of their choice. This would only be exploitable where a server was set up with proxying enabled     but was misconfigured in such a way that the Proxy Error page was displayed. (CVE-2019-10092)

  - In Apache HTTP server 2.4.0 to 2.4.39, Redirects configured with mod_rewrite that were intended to be     self-referential might be fooled by encoded newlines and redirect instead to an unexpected URL within the     request URL. (CVE-2019-10098)

  - In Apache HTTP Server 2.4.0 to 2.4.41, mod_proxy_ftp may use uninitialized memory when proxying to a     malicious FTP server. (CVE-2020-1934)

  - Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in     mod_auth_digest. There is no report of this overflow being exploitable, nor the Apache HTTP Server team     could create one, though some particular compiler and/or compilation option might make it possible, with     limited consequences anyway due to the size (a single byte) and the value (zero byte) of the overflow     (CVE-2020-35452)

  - A crafted method sent through HTTP/2 will bypass validation and be forwarded by mod_proxy, which can lead     to request splitting or cache poisoning. This issue affects Apache HTTP Server 2.4.17 to 2.4.48.
    (CVE-2021-33193)

  - Malformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP     Server 2.4.48 and earlier. (CVE-2021-34798)

  - A carefully crafted request uri-path can cause mod_proxy_uwsgi to read above the allocated memory and     crash (DoS). This issue affects Apache HTTP Server versions 2.4.30 to 2.4.48 (inclusive). (CVE-2021-36160)

  - ap_escape_quotes() may write beyond the end of a buffer when given malicious input. No included modules     pass untrusted data to these functions, but third-party / external modules may. This issue affects Apache     HTTP Server 2.4.48 and earlier. (CVE-2021-39275)

  - If LimitXMLRequestBody is set to allow request bodies larger than 350MB (defaults to 1M) on 32 bit systems     an integer overflow happens which later causes out of bounds writes. This issue affects Apache HTTP Server     2.4.52 and earlier. (CVE-2022-22721)

  - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of     Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This     issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.53 and prior versions.

  - Faulty input validation in the core of Apache allows malicious or exploitable backend/content generators     to split HTTP responses. This issue affects Apache HTTP Server: through 2.4.58. (CVE-2023-38709)

  - An attacker, opening a HTTP/2 connection with an initial window size of 0, was able to block handling of     that connection indefinitely in Apache HTTP Server. This could be used to exhaust worker resources in the     server, similar to the well known slow loris attack pattern. This has been fixed in version 2.4.58, so     that such connection are terminated properly after the configured connection timeout. This issue affects     Apache HTTP Server: from 2.4.55 through 2.4.57. Users are recommended to upgrade to version 2.4.58, which     fixes the issue. (CVE-2023-43622)

  - When a HTTP/2 stream was reset (RST frame) by a client, there was a time window were the request's memory     resources were not reclaimed immediately. Instead, de-allocation was deferred to connection close. A     client could send new requests and resets, keeping the connection busy and open and causing the memory     footprint to keep on growing. On connection close, all resources were reclaimed, but the process might run     out of memory before that. This was found by the reporter during testing of CVE-2023-44487 (HTTP/2 Rapid     Reset Exploit) with their own test client. During normal HTTP/2 use, the probability to hit this bug is     very low. The kept memory would not become noticeable before the connection closes or times out. Users are     recommended to upgrade to version 2.4.58, which fixes the issue. (CVE-2023-45802)

  - HTTP/2 incoming headers exceeding the limit are temporarily buffered in nghttp2 in order to generate an     informative HTTP 413 response. If a client does not stop sending headers, this leads to memory exhaustion.
    (CVE-2024-27316)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Apache httpd installed on the remote host is prior to 2.4.59. It is, therefore, affected by multiple vulnerabilities as referenced in the 2.4.59 advisory.

  - Apache HTTP Server: HTTP Response Splitting in multiple modules: HTTP Response splitting in multiple     modules in Apache HTTP Server allows an attacker that can inject malicious response headers into backend     applications to cause an HTTP desynchronization attack. Users are recommended to upgrade to version     2.4.59, which fixes this issue. Acknowledgements: (CVE-2024-24795)

  - Apache HTTP Server: HTTP/2 DoS by memory exhaustion on endless continuation frames: HTTP/2 incoming     headers exceeding the limit are temporarily buffered in nghttp2 in order to generate an informative HTTP     413 response. If a client does not stop sending headers, this leads to memory exhaustion.
