Description

An issue was discovered in MantisBT before 2.24.5. It associates a unique cookie string with each user. This string is not reset upon logout (i.e., the user session is still considered valid and active), allowing an attacker who somehow gained access to a user's cookie to login as them.

Affected products

• mantisbt: before 2.24.5 — fixed in 2.24.5

How to fix

Upgrade to a fixed version: mantisbt 2.24.5. Check the vendor advisory for mitigations.
