According to the versions of the python packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - http.cookiejar.DefaultPolicy.domain_return_ok in     Lib/http/cookiejar.py in Python before 3.7.3 does not     correctly validate the domain: it can be tricked into     sending existing cookies to the wrong server. An     attacker may abuse this flaw by using a server with a     hostname that has another valid hostname as a suffix     (e.g., pythonicexample.com to steal cookies for     example.com). When a program uses     http.cookiejar.DefaultPolicy and tries to do an HTTP     connection to an attacker-controlled server, existing     cookies can be leaked to the attacker. This affects 2.x     through 2.7.16, 3.x before 3.4.10, 3.5.x before 3.5.7,     3.6.x before 3.6.9, and 3.7.x before     3.7.3.(CVE-2018-20852)

  - An issue was discovered in urllib2 in Python 2.x     through 2.7.16 and urllib in Python 3.x through 3.7.3.
    CRLF injection is possible if the attacker controls a     url parameter, as demonstrated by the first argument to     urllib.request.urlopen with \r\n (specifically in the     path component of a URL that lacks a ? character)     followed by an HTTP header or a Redis command. This is     similar to the CVE-2019-9740 query string     issue.(CVE-2019-9947)

  - An issue was discovered in urllib2 in Python 2.x     through 2.7.16 and urllib in Python 3.x through 3.7.3.
    CRLF injection is possible if the attacker controls a     url parameter, as demonstrated by the first argument to     urllib.request.urlopen with \r\n (specifically in the     query string after a ? character) followed by an HTTP     header or a Redis command.(CVE-2019-9740)

  - An issue was discovered in Python through 2.7.16, 3.x     through 3.5.7, 3.6.x through 3.6.9, and 3.7.x through     3.7.4. The email module wrongly parses email addresses     that contain multiple @ characters. An application that     uses the email module and implements some kind of     checks on the From/To headers of a message could be     tricked into accepting an email address that should be     denied. An attack may be the same as in CVE-2019-11340     however, this CVE applies to Python more     generally.(CVE-2019-16056)

  - The documentation XML-RPC server in Python through     2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has     XSS via the server_title field. This occurs in     Lib/DocXMLRPCServer.py in Python 2.x, and in     Lib/xmlrpc/server.py in Python 3.x. If set_server_title     is called with untrusted input, arbitrary JavaScript     can be delivered to clients that visit the http URL for     this server.(CVE-2019-16935)

  - library/glob.html in the Python 2 and 3 documentation     before 2016 has potentially misleading information     about whether sorting occurs, as demonstrated by     irreproducible cancer-research results. NOTE: the     effects of this documentation cross application     domains, and thus it is likely that security-relevant     code elsewhere is affected. This issue is not a Python     implementation bug, and there are no reports that NMR     researchers were specifically relying on     library/glob.html. In other words, because the older     documentation stated 'finds all the pathnames matching     a specified pattern according to the rules used by the     Unix shell,' one might have incorrectly inferred that     the sorting that occurs in a Unix shell also occurred     for glob.glob. There is a workaround in newer versions     of Willoughby nmr-data_compilation-p2.py and     nmr-data_compilation-p3.py, which call sort()     directly.(CVE-2019-17514)

This update for python3 fixes the following issues :

  - Fixed CVE-2020-27619 (bsc#1178009), where     Lib/test/multibytecodec_support calls eval() on content     retrieved via HTTP.

  - Change setuptools and pip version numbers according to     new wheels

  - Handful of changes to make python36 compatible with     SLE15 and SLE12 (jsc#ECO-2799, jsc#SLE-13738)

  - add triplets for mips-r6 and riscv

  - RISC-V needs CTYPES_PASS_BY_REF_HACK

Update to 3.6.12 (bsc#1179193)

  - Ensure python3.dll is loaded from correct locations when     Python is embedded

  - The __hash__() methods of ipaddress.IPv4Interface and     ipaddress.IPv6Interface incorrectly generated constant     hash values of 32 and 128 respectively. This resulted in     always causing hash collisions. The fix uses hash() to     generate hash values for the tuple of (address, mask     length, network address).

  - Prevent http header injection by rejecting control     characters in http.client.putrequest(&hellip;).

  - Unpickling invalid NEWOBJ_EX opcode with the C     implementation raises now UnpicklingError instead of     crashing.

  - Avoid infinite loop when reading specially crafted TAR     files using the tarfile module

  - This release also fixes CVE-2020-26116 (bsc#1177211) and     CVE-2019-20907 (bsc#1174091).

Update to 3.6.11 :

  - Disallow CR or LF in email.headerregistry. Address     arguments to guard against header injection attacks.

  - Disallow control characters in hostnames in http.client,     addressing CVE-2019-18348. Such potentially malicious     header injection URLs now cause a InvalidURL to be     raised. (bsc#1155094)

  - CVE-2020-8492: The AbstractBasicAuthHandler class of the     urllib.request module uses an inefficient regular     expression which can be exploited by an attacker to     cause a denial of service. Fix the regex to prevent the     catastrophic backtracking. Vulnerability reported by Ben     Caller and Matt Schwager.

The version of AOS installed on the remote host is prior to 5.19.0.5. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.19.0.5 advisory.

  - In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length     checks. In cases where the application calling the library did not perform a sanity check on the inputs it     could result in a crash due to a buffer overflow. (CVE-2019-17006)

  - Heap buffer overflow in the TFTP protocol handler in cURL 7.19.4 to 7.65.3. (CVE-2019-5482)

  - In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.
    When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may     contain files with permissions the attacker did not have or in paths he did not have access to. Extracting     those archives from a high-privilege user without carefully reviewing them may lead to the compromise of     the system. (CVE-2019-14866)

  - If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to     8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the     HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP     headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This     could lead to users seeing responses for unexpected resources. (CVE-2020-13943)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported     versions that are affected are 5.6.45 and prior, 5.7.27 and prior and 8.0.17 and prior. Easily exploitable     vulnerability allows low privileged attacker with network access via multiple protocols to compromise     MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang     or frequently repeatable crash (complete DOS) of MySQL Server. (CVE-2019-2974)

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 AOS installed on the remote host is prior to 5.15.5. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.15.5 advisory.

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2024:0261 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2019-11236:
    In the urllib3 library through 1.24.1 for Python, CRLF injection is possible if the attacker controls the     request parameter.

    CVE-2019-11324:
    The urllib3 library before 1.24.2 for Python mishandles certain cases where the desired set of CA     certificates is different from the OS store of CA certificates, which results in SSL connections     succeeding in situations where a verification failure is the correct outcome. This is related to use of     the ssl_context, ca_certs, or ca_certs_dir argument.

    CVE-2019-16056:
    An issue was discovered in Python through 2.7.16, 3.x through 3.5.7, 3.6.x through 3.6.9, and 3.7.x     through 3.7.4. The email module wrongly parses email addresses that contain multiple @ characters. An     application that uses the email module and implements some kind of checks on the From/To headers of a     message could be tricked into accepting an email address that should be denied. An attack may be the same     as in CVE-2019-11340; however, this CVE applies to Python more generally.

    CVE-2019-16935:
    The documentation XML-RPC server in Python through 2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has     XSS via the server_title field. This occurs in Lib/DocXMLRPCServer.py in Python 2.x, and in     Lib/xmlrpc/server.py in Python 3.x. If set_server_title is called with untrusted input, arbitrary     JavaScript can be delivered to clients that visit the http URL for this server.

    CVE-2019-6446:
    An issue was discovered in NumPy 1.16.0 and earlier. It uses the pickle Python module unsafely, which     allows remote attackers to execute arbitrary code via a crafted serialized object, as demonstrated by a     numpy.load call. NOTE: third parties dispute this issue because it is  a behavior that might have     legitimate applications in (for example)  loading serialized Python object arrays from trusted and     authenticated  sources

    CVE-2019-7164:
    SQLAlchemy through 1.2.17 and 1.3.x through 1.3.0b2 allows SQL Injection via the order_by parameter.

    CVE-2019-7548:
    SQLAlchemy 1.2.17 has SQL Injection when the group_by parameter can be controlled.

    CVE-2019-9636:
    Python 2.7.x through 2.7.16 and 3.x through 3.7.2 is affected by: Improper Handling of Unicode Encoding     (with an incorrect netloc) during NFKC normalization. The impact is: Information disclosure (credentials,     cookies, etc. that are cached against a given hostname). The components are: urllib.parse.urlsplit,     urllib.parse.urlparse. The attack vector is: A specially crafted URL could be incorrectly parsed to locate     cookies or authentication data and send that information to a different host than when parsed correctly.
    This is fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1, v3.5.7, v3.5.8,     v3.5.8rc1, v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12, v3.6.9, v3.6.9rc1;
    v3.7.3, v3.7.3rc1, v3.7.4, v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1,     v3.7.8, v3.7.8rc1, v3.7.9.

    CVE-2019-9740:
    An issue was discovered in urllib2 in Python 2.x through 2.7.16 and urllib in Python 3.x through 3.7.3.
    CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the first argument     to urllib.request.urlopen with \r\n (specifically in the query string after a ? character) followed by an     HTTP header or a Redis command. This is fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10,     v3.5.10rc1, v3.5.8, v3.5.8rc1, v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12,     v3.6.9, v3.6.9rc1; v3.7.4, v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1,     v3.7.8, v3.7.8rc1, v3.7.9.

    CVE-2019-9947:
    An issue was discovered in urllib2 in Python 2.x through 2.7.16 and urllib in Python 3.x through 3.7.3.
    CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the first argument     to urllib.request.urlopen with \r\n (specifically in the path component of a URL that lacks a ? character)     followed by an HTTP header or a Redis command. This is similar to the CVE-2019-9740 query string issue.
    This is fixed in: v2.7.17, v2.7.17rc1, v2.7.18, v2.7.18rc1; v3.5.10, v3.5.10rc1, v3.5.8, v3.5.8rc1,     v3.5.8rc2, v3.5.9; v3.6.10, v3.6.10rc1, v3.6.11, v3.6.11rc1, v3.6.12, v3.6.9, v3.6.9rc1; v3.7.4,     v3.7.4rc1, v3.7.4rc2, v3.7.5, v3.7.5rc1, v3.7.6, v3.7.6rc1, v3.7.7, v3.7.7rc1, v3.7.8, v3.7.8rc1, v3.7.9.

    CVE-2019-9948:
    urllib in Python 2.x through 2.7.16 supports the local_file: scheme, which makes it easier for remote     attackers to bypass protection mechanisms that blacklist file: URIs, as demonstrated by triggering a     urllib.urlopen('local_file:///etc/passwd') call.

    CVE-2020-26137:
    urllib3 before 1.25.9 allows CRLF injection if the attacker controls the HTTP request method, as     demonstrated by inserting CR and LF control characters in the first argument of putrequest(). NOTE: this     is similar to CVE-2020-26116.

    CVE-2020-27619:
    In Python 3 through 3.9.0, the Lib/test/multibytecodec_support.py CJK codec tests call eval() on content     retrieved via HTTP.

    CVE-2020-27783:
    A XSS vulnerability was discovered in python-lxml's clean module. The module's parser didn't properly     imitate browsers, which caused different behaviors between the sanitizer and the user's page. A remote     attacker could exploit this flaw to run arbitrary HTML/JS code.

    CVE-2020-28493:
    This affects the package jinja2 from 0.0.0 and before 2.11.3. The ReDoS vulnerability is mainly due to the     `_punctuation_re regex` operator and its use of multiple wildcards. The last wildcard is the most     exploitable as it searches for trailing punctuation. This issue can be mitigated by Markdown to format     user content instead of the urlize filter, or by implementing request timeouts and limiting process     memory.

    CVE-2021-20095:
    A flaw was found in python-babel. A path traversal vulnerability was found in how locale data files are     checked and loaded within python-babel, allowing a local attacker to trick an application that uses     python-babel to load a file outside of the intended locale directory. The highest threat from this     vulnerability is to data confidentiality and integrity as well as service availability.

    CVE-2021-23336:
    The package python/cpython from 0 and before 3.6.13, from 3.7.0 and before 3.7.10, from 3.8.0 and before     3.8.8, from 3.9.0 and before 3.9.2 are vulnerable to Web Cache Poisoning via urllib.parse.parse_qsl and     urllib.parse.parse_qs by using a vector called parameter cloaking. When the attacker can separate query     parameters using a semicolon (;), they can cause a difference in the interpretation of the request between     the proxy (running with default configuration) and the server. This can result in malicious requests being     cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and     therefore would not include it in a cache key of an unkeyed parameter.

    CVE-2021-28957:
    An XSS vulnerability was discovered in python-lxml's clean module versions before 4.6.3. When disabling     the safe_attrs_only and forms arguments, the Cleaner class does not remove the formaction attribute     allowing for JS to bypass the sanitizer. A remote attacker could exploit this flaw to run arbitrary JS     code on users who interact with incorrectly sanitized HTML. This issue is patched in lxml 4.6.3.

    CVE-2021-3177:
    Python 3.x through 3.9.1 has a buffer overflow in PyCArg_repr in _ctypes/callproc.c, which may lead to     remote code execution in certain Python applications that accept floating-point numbers as untrusted     input, as demonstrated by a 1e300 argument to c_double.from_param. This occurs because sprintf is used     unsafely.

    CVE-2021-3733:
    There's a flaw in urllib's AbstractBasicAuthHandler class. An attacker who controls a malicious HTTP     server that an HTTP client (such as web browser) connects to, could trigger a Regular Expression Denial of     Service (ReDOS) during an authentication request with a specially crafted payload that is sent by the     server to the client. The greatest threat that this flaw poses is to application availability.

    CVE-2021-3737:
    A flaw was found in python. An improperly handled HTTP response in the HTTP client code of python may     allow a remote attacker, who controls the HTTP server, to make the client script enter an infinite loop,     consuming CPU time. The highest threat from this vulnerability is to system availability.

    CVE-2021-4189:
    A flaw was found in Python, specifically in the FTP (File Transfer Protocol) client library in PASV     (passive) mode. The issue is how the FTP client trusts the host from the PASV response by default. This     flaw allows an attacker to set up a malicious FTP server that can trick FTP clients into connecting back     to a given IP address and port. This vulnerability could lead to FTP client scanning ports, which     otherwise would not have been possible.

    CVE-2021-42771:
    Babel.Locale in Babel before 2.9.1 allows attackers to load arbitrary locale .dat files (containing     serialized Python objects) via directory traversal, leading to code execution.

    CVE-2021-43818:
    lxml is a library for processing XML and HTML in the Python language. Prior to version 4.6.5, the HTML     Cleaner in lxml.html lets certain crafted script content pass through, as well as script content in SVG     files embedded using data URIs. Users that employ the HTML cleaner in a security relevant context should     upgrade to lxml 4.6.5 to receive a patch. There are no known workarounds available.

    CVE-2022-0391:
    A flaw was found in Python, specifically within the urllib.parse module. This module helps break Uniform     Resource Locator (URL) strings into components. The issue involves how the urlparse method does not     sanitize input and allows characters like '\r' and '\n' in the URL path. This flaw allows an attacker to     input a crafted URL, leading to injection attacks. This flaw affects Python versions prior to 3.10.0b1,     3.9.5, 3.8.11, 3.7.11 and 3.6.14.

    CVE-2022-45061:
    An issue was discovered in Python before 3.11.1. An unnecessary quadratic algorithm exists in one path     when processing some inputs to the IDNA (RFC 3490) decoder, such that a crafted, unreasonably long name     being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by     remote servers that could be controlled by a malicious actor; in such a scenario, they could trigger     excessive CPU consumption on the client attempting to make use of an attacker-supplied supposed hostname.
    For example, the attack payload could be placed in the Location header of an HTTP response with status     code 302. A fix is planned in 3.11.1, 3.10.9, 3.9.16, 3.8.16, and 3.7.16.
