"According to the versions of the python-jinja2 package installed, the EulerOS installation on the remote host is
affected by the following vulnerabilities :

    Jinja is an extensible templating engine. Prior to 3.1.5, An oversight in how the Jinja sandboxed
    environment detects calls to str.format allows an attacker that controls the content of a template to
    execute arbitrary Python code. To exploit the vulnerability, an attacker needs to control the content of a
    template. Whether that is the case depends on the type of application using Jinja. This vulnerability
    impacts users of applications which execute untrusted templates. Jinja's sandbox does catch calls to
    str.format and ensures they don't escape the sandbox. However, it's possible to store a reference to a
    malicious string's format method, then pass that to a filter that calls it. No such filters are built-in
    to Jinja, but could be present through custom filters in an application. After the fix, such indirect
    calls are also handled by the sandbox.(CVE-2024-56326)

    Jinja is an extensible templating engine. In versions on the 3.x branch prior to 3.1.5, a bug in the Jinja
    compiler allows an attacker that controls both the content and filename of a template to execute arbitrary
    Python code, regardless of if Jinja's sandbox is used. To exploit the vulnerability, an attacker needs to
    control both the filename and the contents of a template. Whether that is the case depends on the type of
    application using Jinja. This vulnerability impacts users of applications which execute untrusted
    templates where the template author can also choose the template filename.(CVE-2024-56201)

Tenable has extracted the preceding description block directly from the EulerOS python-jinja2 security advisory.

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