high Nessus Plugin ID 154337

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 ESM / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5121-1 advisory.

 Andre Protas, Richard Cloke, and Andy Nuttall discovered that Mailman did not properly associate cross- site request forgery (CSRF) tokens to specific accounts. A remote attacker could use this to perform a CSRF attack to gain access to another account. (CVE-2021-42097)

 Andre Protas, Richard Cloke, and Andy Nuttall discovered that Mailman's cross-site request forgery (CSRF) tokens for the options page are derived from the admin password. A remote attacker could possibly use this to assist in performing a brute force attack against the admin password. (CVE-2021-42096)

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

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

Solution

Update the affected mailman package.
