Cisco Patches High-Severity SQL Injection Vulnerability in Unified CM

Cisco patched a high-severity SQL injection vulnerability in Unified Communications Manager (CM) and Unified Communications Manager Session Management Edition (CM SME).

Cisco on Wednesday announced patches for a high-severity SQL injection vulnerability in Unified Communications Manager (CM) and Unified Communications Manager Session Management Edition (CM SME).

Designed as enterprise call and session management platforms, Cisco Unified CM and Unified CM SME ensure the interoperability of applications such as Webex, Jabber, and more, while also maintaining availability and security.

Tracked as CVE-2023-20010 (CVSS score of 8.1), the vulnerability exists because user input is improperly validated in the web-based management interface of the platforms. The bug allows a remote, authenticated attacker to launch an SQL injection attack on a vulnerable system.

“An attacker could exploit this vulnerability by authenticating to the application as a low-privileged user and sending crafted SQL queries to an affected system. A successful exploit could allow the attacker to read or modify any data on the underlying database or elevate their privileges,” Cisco notes in an advisory.

The security defect impacts Cisco Unified CM and Unified CM SME versions 11.5(1), 12.5(1), and 14, and was addressed in version 12.5(1)SU7 of the applications. A patch will also be included in version 14SU3, which is scheduled for March 2023.

On Wednesday, the tech giant also informed customers of a medium-severity URL filtering bypass vulnerability in AsyncOS software for Email Security Appliance (ESA). A remote, unauthenticated attacker could exploit the bug using crafted URLs.

This week, Cisco also announced patches for three medium severity bugs in Expressway Series and TelePresence Video Communication Server (VCS).

Impacting the API and web-based management interfaces of these products, the flaws could be exploited by an authenticated, remote attacker to write files or access sensitive data on a vulnerable device. All Expressway Series and TelePresence VCS releases prior to 14.0.7 are impacted.

Cisco says it is not aware of any of these vulnerabilities being exploited in the wild. Further information on the flaws can be found on Cisco’s product security page.
