Synopsis

The remote device is missing a vendor-supplied security patch

Description

According to its self-reported version, Cisco IOS XR Software is affected by a privilege escalation vulnerability in a CLI command related to the virtualization manager (VMAN) for Cisco ASR 9000 Series Aggregation Services Routers. This is due to insufficient validation of arguments passed to a specific VMAN CLI command on an affected device. An authenticated, local attacker can exploit this, by including malicious input as the argument of an affected command, in order to run arbitrary commands on the underlying operating system with root privileges, which may lead to complete system compromise.
