Description

Asterisk is an open source private branch exchange and telephony toolkit. Prior to Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3, the PostgreSQL and TDS/MSSQL Channel Event Log backends cel_pgsql and cel_tds may permit arbitrary SQL execution when untrusted data is set in the CEL eventtype column by the CELGenUserEvent dialplan application. The cel_pgsql or cel_tds backend must be loaded and configured, and the administrator must call CELGenUserEvent in the dialplan without ensuring that only valid data is passed to the application. This issue is fixed in Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3.
