Cisco Fixes Critical Vulnerability in CCMP

Cisco patches for a critical vulnerability in Unified Contact Center Management Portal (Unified CCMP) and Unified Contact Center Domain Manager (Unified CCDM) that could be exploited remotely to elevate privileges to administrator.

Tracked as CVE-2022-20658 (CVSS score of 9.6), the issue exists because there was no server-side validation of user permissions, which allowed an attacker to submit a crafted HTTP request to exploit the bug on a vulnerable system.

A successful exploit could allow the attacker to create Administrator accounts. With these accounts, the attacker could access and modify telephony and user resources across all the Unified platforms that are associated to the vulnerable Cisco Unified CCMP.

Cisco Statement

The company also notes that an attacker would need to have valid Advanced User credentials to successfully exploit the vulnerability. Cisco Unified CCMP and Unified CCDM running with the default settings are impacted by the bug.

The security flaw was addressed with the release of Unified CCMP/ Unified CCDM versions 11.6.1 ES17, 12.0.1 ES5, and 12.5.1 ES5. Version 12.6.1 of the software is not affected.

Cisco says it is not aware of the vulnerability being exploited in malicious attacks.
