Descriptions

Quassel before 0.12.2 does not properly re-initialize the database session when the PostgreSQL database is restarted, which allows remote attackers to conduct SQL injection attacks via a \ (backslash) in a message. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-4422.

Quassel anterior a 0.12.2 no maneja debidamente la reinicialización de la sesión de la base de datos cuando la base de datos PostgreSQL es reiniciada, lo que permite a atacantes remotos llevar a cabo ataques de inyección SQL a través de \ (barra invertida) en un mensaje. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2013-4422.

It was discovered that the fix for CVE-2013-4422 in quassel, a distributed IRC client, was incomplete. This could allow remote attackers to inject SQL queries after a database reconnection (e.g. when the backend PostgreSQL server is restarted).
