Cisco Application Policy Infrastructure Controller Custom Binary Privilege Escalation Vulnerability

A vulnerability in the build procedure for certain executable system files installed at boot time on Cisco Application Policy Infrastructure Controller (APIC) devices could allow an authenticated, local attacker to gain root-level privileges.

The vulnerability is due to a custom executable system file that was built to use relative search paths for libraries without properly validating the library to be loaded. An attacker could exploit this vulnerability by authenticating to the device and loading a malicious library that can escalate the privilege level.

Checks if a vulnerable version is present on the target host.

See the referenced vendor advisory for a solution.
