Authenticated command injection in Cisco Secure Firewall Management Center (FMC) lockdown remediation modules
A vulnerability in the lockdown mechanism of Cisco Secure Firewall Management Center (FMC) Software allows an authenticated local attacker with valid administrative credentials to execute arbitrary commands as root. The issue is caused by insufficient restrictions on remediation modules while the system is in lockdown mode. An attacker can exploit the flaw by providing crafted input to the system CLI of an affected device, resulting in arbitrary command execution (and potentially arbitrary code execution) with root privileges even when lockdown mode is enabled.
