Name of the Vulnerable Software and Affected Versions BMC Patrol Agent version 9.0.10i

Description An issue was discovered that allows an attacker with "patrol" privileges to elevate their privileges to those of the "root" user. This can be achieved by specially crafting a shared library .so file that will be loaded during execution, taking advantage of weak execution permissions on the PatrolAgent SUID binary.

Recommendations For BMC Patrol Agent version 9.0.10i, consider restricting access to the PatrolAgent SUID binary to prevent exploitation. Additionally, monitor for any suspicious shared library .so files that could be used to elevate privileges. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
