## Overview

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.

## Affected

- `asterisk >= 21.0.0-pre1, < 21.12.3`

- `asterisk >= 23.0.0-pre1, < 23.4.1`
