No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

A vulnerability in the Cisco Unified Computing System (UCS) Manager, Cisco Firepower 4100 Series Next-Generation Firewall (NGFW), and Cisco Firepower 9300 Security Appliance could allow an authenticated, local attacker to obtain root shell privileges on the device, aka Command Injection. The vulnerability is due to improper validation of string input in the shell application. An attacker could exploit this vulnerability through the use of malicious commands. A successful exploit could allow the attacker to obtain root shell privileges on the device. Cisco Bug IDs: CSCvf20741, CSCvf60078.
