CVE-2017-6773: Input Validation

First published: Thu Aug 17 2017(Updated: )

A vulnerability in the CLI of Cisco ASR 5000 Series Aggregated Services Routers running the Cisco StarOS operating system could allow an authenticated, local attacker to bypass the CLI restrictions and execute commands on the underlying operating system. The vulnerability is due to insufficient input sanitization of user-supplied input at the CLI. An attacker could exploit this vulnerability by crafting a script on the device that will allow them to bypass built-in restrictions. An exploit could allow the unauthorized user to launch the CLI directly from a command shell. Cisco Bug IDs: CSCvd47722. Known Affected Releases: 21.0.v0.65839.
