CVE-2024-48872
vulnerability analysis and mitigation

Overview

A race condition vulnerability was identified in Mattermost versions 10.1.x <= 10.1.2, 10.0.x <= 10.0.2, 9.11.x <= 9.11.4, and 9.5.x <= 9.5.12. The vulnerability (CVE-2024-48872) was disclosed on December 16, 2024, and involves a concurrent execution issue that affects the login attempt restriction mechanism (NVD).

Technical details

The vulnerability is classified as a race condition (CWE-362) where the system fails to prevent concurrent checking and updating of failed login attempts. This implementation flaw allows for improper synchronization when handling shared resources. The vulnerability has been assigned a CVSS v3.1 base score of 4.8 (Medium) with the vector string CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N (NVD).

Impact

The vulnerability enables attackers to bypass the 'Max failed attempts' restriction by simultaneously sending multiple login requests. This bypass allows attackers to attempt a large number of login attempts before being blocked, potentially compromising the system's authentication security measures (NVD).

Mitigation and workarounds

Users should upgrade to the latest version of Mattermost that contains the security fix. The vulnerability has been addressed in versions newer than 10.1.2, 10.0.2, 9.11.4, and 9.5.12 respectively (NVD).
