Description
A vulnerability in the Java Remote Management Interface of Cisco Unified Contact Center Express (Unified CCX) could allow an unauthenticated, remote attacker to execute arbitrary code on an affected device. The vulnerability is due to insecure deserialization of user-supplied content by the affected software. An attacker could exploit this vulnerability by sending a malicious serialized Java object to a specific listener on an affected system. A successful exploit could allow the attacker to execute arbitrary code as the root user on an affected device.

Report as Exploited in the Wild
What do we mean by "exploited in the wild"?
By selecting this, you are verifying to the AttackerKB community that either you, or a reputable source (example: a security vendor or researcher), has observed an active attempt by attackers, or IOCs related, to exploit this vulnerability outside of a research environment.
A vulnerability should also be considered "exploited in the wild" if there is a publicly available PoC or exploit (example: in an exploitation framework like Metasploit).
To add to this, we were unable to obtain the software without a valid Cisco service contract, so no patch analysis was performed.
