Summary

Cisco Emergency Responder, Cisco Unified Communications Manager, Cisco Unified Communications Manager IM and Presence Service, and Cisco Unity Connection are affected in releases starting from 14 and 15, as the sources list. The product does not properly neutralize special characters in input used in an SQL command (CWE-89), so input can change the SQL queries the product runs. A remote attacker with low privileges and no user interaction can affect confidentiality, integrity and availability.
