high Nessus Plugin ID 178680

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-6232-1 advisory.

It was discovered that wkhtmltopdf was not properly enforcing the same-origin policy when processing certain HTML files. If a user or automated system using wkhtmltopdf were tricked into processing a specially crafted HTML file, an attacker could possibly use this issue to expose sensitive information.

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
