CVE-2022-41974
Published: 24 October 2022
multipath-tools 0.7.0 through 0.9.x before 0.9.2 allows local users to obtain root access, as exploited alone or in conjunction with CVE-2022-41973. Local users able to write to UNIX domain sockets can bypass access controls and manipulate the multipath setup. This can lead to local privilege escalation to root. This occurs because an attacker can repeat a keyword, which is mishandled because arithmetic ADD is used instead of bitwise OR.
Notes
| Author | Note |
|---|---|
| alexmurray | introduced in version 0.7.0 via commit 9acda0c but earlier versions do no authorization checks at all and are then technically also vulnerable |
| rodrigo-zaiden | earlier versions are not getting a code fix for this and applying one without upstream support does not seem feasible and can add too much risks. |
