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

  - A use-after-free exists in Python through 3.9 via heappushpop in heapq. (CVE-2022-48560)

  - An XML External Entity (XXE) issue was discovered in Python through 3.9.1. The plistlib module no longer     accepts entity declarations in XML plist files to avoid XML vulnerabilities. (CVE-2022-48565)

  - An issue was discovered in compare_digest in Lib/hmac.py in Python through 3.9.1. Constant-time-defeating     optimisations were possible in the accumulator variable in hmac.compare_digest. (CVE-2022-48566)

  - An issue was discovered in Python before 3.8.18, 3.9.x before 3.9.18, 3.10.x before 3.10.13, and 3.11.x     before 3.11.5. It primarily affects servers (such as HTTP servers) that use TLS client authentication. If     a TLS server-side socket is created, receives data into the socket buffer, and then is closed quickly,     there is a brief window where the SSLSocket instance will detect the socket as 'not connected' and won't     initiate a handshake, but buffered data will still be readable from the socket buffer. This data will not     be authenticated if the server-side TLS peer is expecting client certificate authentication, and is     indistinguishable from valid TLS stream data. Data is limited in size to the amount that will fit in the     buffer. (The TLS connection cannot directly be used for data exfiltration because the vulnerable code path     requires that the connection be closed on initialization of the SSLSocket.) (CVE-2023-40217)

    This update fixes multiple vulnerabilities concerning the urlparse module as     well as vulnerabilities concerning the heapq, hmac, plistlib and ssl modules.

    CVE-2021-23336

        Python was vulnerable to Web Cache Poisoning via urlparse.parse_qsl and         urlparse.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-2022-0391

        The urlparse 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.

    CVE-2022-48560

        A use-after-free exists in Python via heappushpop in heapq.

    CVE-2022-48565

        An XML External Entity (XXE) issue was discovered in Python.  The plistlib         module no longer accepts entity declarations in XML plist files to avoid         XML vulnerabilities.

    CVE-2022-48566

        An issue was discovered in compare_digest in Lib/hmac.py in Python.
        Constant-time-defeating optimisations were possible in the accumulator         variable in hmac.compare_digest.

    CVE-2023-24329

        An issue in the urlparse component of Python allows attackers to bypass         blocklisting methods by supplying a URL that starts with blank characters.

    CVE-2023-40217

        The issue primarily affects servers written in Python (such as HTTP         servers) that use TLS client authentication. If a TLS server-side socket is         created, receives data into the socket buffer, and then is closed quickly,         there is a brief window where the SSLSocket instance will detect the socket         as not connected and won't initiate a handshake, but buffered data will         still be readable from the socket buffer.  This data will not be         authenticated if the server-side TLS peer is expecting client certificate         authentication, and is indistinguishable from valid TLS stream data. Data         is limited in size to the amount that will fit in the buffer. (The TLS         connection cannot directly be used for data exfiltration because the         vulnerable code path requires that the connection be closed on         initialization of the SSLSocket.)


    For Debian 10 buster, these problems have been fixed in version     2.7.16-2+deb10u3.

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

The remote NewStart CGSL host, running version MAIN 6.06 (SP), has python3 packages installed that are affected by multiple vulnerabilities:

  - Python 3.x through 3.10 has an open redirection vulnerability in lib/http/server.py due to no protection     against multiple (/) at the beginning of URI path which may leads to information disclosure. NOTE: this is     disputed by a third party because the http.server.html documentation page states Warning: http.server is     not recommended for production. It only implements basic security checks. (CVE-2021-28861)

  - A flaw was found in python. In algorithms with quadratic time complexity using non-binary bases, when     using int(text), a system could take 50ms to parse an int string with 100,000 digits and 5s for     1,000,000 digits (float, decimal, int.from_bytes(), and int() for binary bases 2, 4, 8, 16, and 32 are not     affected). The highest threat from this vulnerability is to system availability. (CVE-2020-10735)

  - 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. (CVE-2022-45061)

  - A use-after-free exists in Python through 3.9 via heappushpop in heapq. (CVE-2022-48560)

  - read_ints in plistlib.py in Python through 3.9.1 is vulnerable to a potential DoS attack via CPU and RAM     exhaustion when processing malformed Apple Property List files in binary format. (CVE-2022-48564)
