The version of python installed on the remote host is prior to 2.7.18-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-1980 advisory.

    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)

    An issue in the urllib.parse component of Python before v3.11 allows attackers to bypass blocklisting     methods by supplying a URL that starts with blank characters. (CVE-2023-24329)

The remote host is affected by the vulnerability described in GLSA-202305-02 (Python, PyPy3: Multiple Vulnerabilities)

  - In Python (aka CPython) up to 3.10.8, the mailcap module does not add escape characters into commands     discovered in the system mailcap file. This may allow attackers to inject shell commands into applications     that call mailcap.findmatch with untrusted input (if they lack validation of user-provided filenames or     arguments). The fix is also back-ported to 3.7, 3.8, 3.9 (CVE-2015-20107)

  - A vulnerability was found in openstack-nova's console proxy, noVNC. By crafting a malicious URL, noVNC     could be made to redirect to any desired URL. (CVE-2021-3654)

  - The urllib3 library 1.26.x before 1.26.4 for Python omits SSL certificate validation in some cases     involving HTTPS to HTTPS proxies. The initial connection to the HTTPS proxy (if an SSLContext isn't given     via proxy_config) doesn't verify the hostname of the certificate. This means certificates for different     servers that still validate properly with the default urllib3 SSLContext will be silently accepted.
    (CVE-2021-28363)

  - ** DISPUTED ** 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)

  - In Python before 3,9,5, the ipaddress library mishandles leading zero characters in the octets of an IP     address string. This (in some situations) allows attackers to bypass access control that is based on IP     addresses. (CVE-2021-29921)

  - 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-2022-0391)

  - The Keccak XKCP SHA-3 reference implementation before fdc6fef has an integer overflow and resultant buffer     overflow that allows attackers to execute arbitrary code or eliminate expected cryptographic properties.
    This occurs in the sponge function interface. (CVE-2022-37454)

  - Python 3.9.x before 3.9.16 and 3.10.x before 3.10.9 on Linux allows local privilege escalation in a non-     default configuration. The Python multiprocessing library, when used with the forkserver start method on     Linux, allows pickles to be deserialized from any user in the same machine local network namespace, which     in many system configurations means any user on the same machine. Pickles can execute arbitrary code.
    Thus, this allows for local user privilege escalation to the user that any forkserver process is running     as. Setting multiprocessing.util.abstract_sockets_supported to False is a workaround. The forkserver start     method for multiprocessing is not the default start method. This issue is Linux specific because only     Linux supports abstract namespace sockets. CPython before 3.9 does not make use of Linux abstract     namespace sockets by default. Support for users manually specifying an abstract namespace socket was added     as a bugfix in 3.7.8 and 3.8.3, but users would need to make specific uncommon API calls in order to do     that in CPython before 3.9. (CVE-2022-42919)

  - 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)

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

According to the versions of the python3 packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
