CWE-78

Summary

A vulnerability in the web management GUI of the Cisco D9800 Network Transport
Receiver could allow an authenticated, remote attacker to perform a command 
injection attack.

The vulnerability is due to insufficient input validation of GUI command 
arguments. An attacker could exploit this vulnerability by injecting crafted 
arguments into a vulnerable GUI command. An exploit could allow the attacker 
to execute commands on the underlying BusyBox operating system. These commands
are run at the privilege level of the authenticated user. The attacker needs 
valid device credentials for this attack.

There are no workarounds that address this vulnerability.
