Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

CVE-2024-48872

Medium
4.8/10

Summary

Mattermost versions 9.5.x prior to 9.5.13-rc1, 9.11.x prior to 9.11.5-rc1, 10.0.x prior to 10.0.3-rc1, and 10.1.x prior to 10.1.3-rc1 fail to prevent concurrently checking and updating the failed login attempts. Which allows an attacker to bypass of "Max failed attempts" restriction and send a big number of login attempts before being blocked via simultaneously sending multiple login requests.

CWE-362 - Race Condition

A race condition occurs in a shared memory program when two threads/processes access the same shared memory data, and at least one thread executes a write operation. This vulnerability manipulates the time to check vs. time to use (TOC/TOU) gap between the threads in the critical section to cause disorientation in the shared data. The impact can vary from compromising the confidentiality of the system to causing the system to crash or to execute arbitrary code.
