CVE-2022-41974
CVSS v3.1
7.8
High
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
multipath-tools versions 0.7.0 through 0.9.x before 0.9.2
multipath-tools versions prior to 0.9.2
Description
The issue is related to errors in privilege management, allowing an attacker to elevate their privileges to root. Local users who can write to UNIX domain sockets can bypass access controls and manipulate the multipath setup, leading to local privilege escalation. This occurs because an attacker can repeat a keyword, which is mishandled due to the use of arithmetic ADD instead of bitwise OR.
Recommendations
For multipath-tools versions 0.7.0 through 0.9.x before 0.9.2, update to version 0.9.2 or later to resolve the issue.
For multipath-tools versions prior to 0.9.2, update to version 0.9.2 or later to resolve the issue.
As a temporary workaround, consider restricting access to UNIX domain sockets to minimize the risk of exploitation.
