CWE-77

Summary

A vulnerability in the CLI of the Cisco StarOS operating system for Cisco ASR
5000 Series Aggregation Services Routers could allow an authenticated, local
attacker to perform a command injection attack on an affected system.
The vulnerability is due to insufficient validation of commands that are
supplied to certain configurations in the CLI of the affected operating
system. An attacker could exploit this vulnerability by injecting crafted
arguments into a vulnerable CLI command for an affected system. A successful
exploit could allow the attacker to insert and execute arbitrary commands in
the CLI of the affected system. To exploit this vulnerability, the attacker
would need to authenticate to an affected system by using valid administrator
credentials.
There are no workarounds that address this vulnerability.
