Debian DLA-2791-1 : mailman - LTS security update

high Nessus Plugin ID 154427

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-2791 advisory.

- GNU Mailman before 2.1.35 may allow remote Privilege Escalation. A certain csrf_token value is derived from the admin password, and may be useful in conducting a brute-force attack against that password.
(CVE-2021-42096)

- GNU Mailman before 2.1.35 may allow remote Privilege Escalation. A csrf_token value is not specific to a single user account. An attacker can obtain a value within the context of an unprivileged user account, and then use that value in a CSRF attack against an admin (e.g., for account takeover). (CVE-2021-42097)

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

Solution

Upgrade the mailman packages.

For Debian 9 Stretch, these problems have been fixed in version 1
