"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2024:0271 advisory.

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

    CVE-2024-11168:
    The urllib.parse.urlsplit() and urlparse() functions improperly validated bracketed hosts (`[]`), allowing
    hosts that weren't IPv6 or IPvFuture. This behavior was not conformant to RFC 3986 and potentially enabled
    SSRF if a URL is processed by more than one URL parser.

    CVE-2024-9287:
    A vulnerability has been found in the CPython `venv` module and CLI where path names provided when
    creating a virtual environment were not quoted properly, allowing the creator to inject commands into
    virtual environment activation scripts (ie source venv/bin/activate). This means that attacker-
    controlled virtual environments are able to run commands when the virtual environment is activated.
    Virtual environments which are not created by an attacker or which aren't activated before being used (ie
    ./venv/bin/python) are not affected.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

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