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.” reads the advisory published by the IT giant. “A successful exploit could allow the attacker to read or modify any data on the underlying database or elevate their privileges.”

The flaw impacts Cisco Unified CM and Unified CM SME versions 11.5(1), 12.5(1), and 14. The company advises customers to upgrade to an appropriate fixed software release as reported in the following table:
