critical Nessus Plugin ID 207695

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 22.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-7030-1 advisory.

It was discovered that py7zr was vulnerable to path traversal attacks. If a user or automated system were tricked into extracting a specially crafted 7z archive, an attacker could possibly use this issue to write arbitrary files outside the target directory on the host.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution

Update the affected python3-py7zr package.
