"The remote EulerOS host is missing multiple security updates.");
  script_set_attribute(attribute:"description", value:
"According to the versions of the python-pip packages installed, the EulerOS installation on the remote host is affected
by the following vulnerabilities :

    urllib3 is a user-friendly HTTP client library for Python. Prior to 2.5.0, it is possible to disable
    redirects for all requests by instantiating a PoolManager and specifying retries in a way that disable
    redirects. By default, requests and botocore users are not affected. An application attempting to mitigate
    SSRF or open redirect vulnerabilities by disabling redirects at the PoolManager level will remain
    vulnerable. This issue has been patched in version 2.5.0.(CVE-2025-50181)

    Requests is a HTTP library. Since Requests 2.3.0, Requests has been leaking Proxy-Authorization headers to
    destination servers when redirected to an HTTPS endpoint. This is a product of how we use
    `rebuild_proxies` to reattach the `Proxy-Authorization` header to requests. For HTTP connections sent
    through the tunnel, the proxy will identify the header in the request itself and remove it prior to
    forwarding to the destination server. However when sent over HTTPS, the `Proxy-Authorization` header must
    be sent in the CONNECT request as the proxy has no visibility into the tunneled request. This results in
    Requests forwarding proxy credentials to the destination server unintentionally, allowing a malicious
    actor to potentially exfiltrate sensitive information. This issue has been patched in version
    2.31.0.(CVE-2023-32681)

    When extracting a tar archive pip may not check symbolic links point into the extraction directory if the
    tarfile module doesn't implement PEP 706.
    Note that upgrading pip to a 'fixed' version for this vulnerability doesn't fix all known vulnerabilities
    that are remediated by using a Python version that implements PEP 706.

    Note that this is a vulnerability in pip's fallback implementation of tar extraction for Python versions
    that don't implement PEP 706
    and therefore are not secure to all vulnerabilities in the Python 'tarfile' module. If you're using a
    Python version that implements PEP 706
    then pip doesn't use the 'vulnerable' fallback code.

    Mitigations include upgrading to a version of pip that includes the fix, upgrading to a Python version
    that implements PEP 706 (Python =3.9.17, =3.10.12, =3.11.4, or =3.12),
    applying the linked patch, or inspecting source distributions (sdists) before installation as is already a
    best-practice.(CVE-2025-8869)

Tenable has extracted the preceding description block directly from the EulerOS python-pip security advisory.

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