The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dla-3715 advisory.
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.Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

- 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.
