Name of the Vulnerable Software and Affected Versions Linux targetcli-fb versions 2.1.50 through 2.1.51

Description A flaw in the targetcli-fb component of Linux allows a local attacker to escalate their privileges to root due to inadequate access control. The issue is related to the world-writable socket used by targetclid, which can be exploited to modify the iSCSI configuration if the targetclid socket is enabled.

Recommendations For Linux targetcli-fb versions 2.1.50 and 2.1.51, consider restricting access to the targetclid socket to prevent exploitation until a patch is available. As a temporary workaround, consider disabling the targetclid socket until a fix is provided to prevent privilege escalation.
