Trust: 0.8

sources: JVNDB: JVNDB-2020-005764

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. Cisco Unified Contact Center Express Exists in an unreliable data deserialization vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. This component supports functions such as self-service voice service, call distribution, and customer access control
