Can you explain this vulnerability to me?

This vulnerability in Cisco Unified Contact Center Express (Unified CCX) Editor is caused by insecure deserialization of Java objects. An attacker can exploit it by convincing an authenticated local user to open a specially crafted .aef file in the editor. This allows the attacker to execute arbitrary code on the host with the same privileges as the user running the editor. [1]
