Asterisk Postgres Realtime Engine SQL Injection
A vulnerability has been reported in Asterisk, which can be exploited by malicious people to conduct SQL injection attacks.
Input passed as lookup data to the Postgres Realtime Engine is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
Successful exploitation requires that the module is configured and used.
The vulnerability is reported in all Asterisk 1.4.x versions before 1.4.15.
Solution:
Update to Asterisk version 1.4.15.
Use the PgsqlODBC driver instead of the vulnerable module.
