Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 11 host has packages installed that are affected by a vulnerability as referenced in the dsa-5260 advisory.

 - In Linaro Automated Validation Architecture (LAVA) before 2022.10, there is dynamic code execution in lava_server/lavatable.py. Due to improper input sanitization, an anonymous user can force the lava-server- gunicorn service to execute user-provided code on the server. (CVE-2022-42902)

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

Solution

For the stable distribution (bullseye), this problem has been fixed in version 2020.12-5+deb11u1.
