Cisco Unified CM SQL Injection Flaw Let Attackers Execute Crafted SQL Queries

Cisco released fixes for Unified Communications Manager (CM) and Unified Communications Manager Session Management Edition to address high-severity SQL injection vulnerability.

“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”, Cisco reports.

“A successful exploit could allow the attacker to read or modify any data on the underlying database or elevate their privileges”.

Cisco Unified CM and Unified CM SME, which are intended as enterprise call and session management systems, guarantee the compatibility of apps like Webex, Jabber, and more while upholding availability and security.

The vulnerability is tracked as CVE-2023-20010 (CVSS score of 8.1). It arises because user input in the web-based management interface of the platforms is not properly validated.

The flaw enables a remote, authenticated attacker to attack a system that is vulnerable to a SQL injection attack.
