The remote Ubuntu host is missing one or more security updates.


The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4629-1 advisory.

- MoinMoin is a wiki engine. In MoinMoin before version 1.9.11, an attacker with write permissions can upload an SVG file that contains malicious javascript. This javascript will be executed in a user's browser when the user is viewing that SVG file on the wiki. Users are strongly advised to upgrade to a patched version. MoinMoin Wiki 1.9.11 has the necessary fixes and also contains other important fixes.

- The cache action in action/cache.py in MoinMoin through 1.9.10 allows directory traversal through a crafted HTTP request. An attacker who can upload attachments to the wiki can use this to achieve remote code execution. (CVE-2020-25074)

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


Update the affected python-moinmoin package.
