Critical Vulnerability in Cisco Secure Firewall Management Center and Security Cloud Control

What changed

A significant vulnerability has been discovered in the web-based management interface of Cisco Secure Firewall Management Center (FMC) Software and Cisco Security Cloud Control (SCC). This flaw is classified as a deserialization of untrusted data issue, which could allow an unauthenticated attacker to execute arbitrary Java code with root privileges on affected devices.

The vulnerability arises from the insecure handling of user-supplied Java byte streams, making it possible for attackers to exploit the system by sending specially crafted serialized Java objects.
