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

    Jinja is an extensible templating engine. Special placeholders in the template allow writing code similar
    to Python syntax. It is possible to inject arbitrary HTML attributes into the rendered HTML template,
    potentially leading to Cross-Site Scripting (XSS). The Jinja `xmlattr` filter can be abused to inject
    arbitrary HTML attribute keys and values, bypassing the auto escaping mechanism and potentially leading to
    XSS. It may also be possible to bypass attribute validation checks if they are blacklist-
    based.(CVE-2024-22195)

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

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