CVE-2015-3427

High
Published: Translated: NVD NIST

Summary

A vulnerability in Quassel before version 0.12.2 is due to improper re-initialization of the database session after a PostgreSQL restart. This allows a remote attacker to perform SQL injection by sending a message containing a backslash character. This is an incomplete fix for CVE-2013-4422.

Risk Assessment

An attacker can inject malicious SQL queries into the database, potentially leading to data leakage, modification, or deletion, as well as privilege escalation within the system.

Recommendation

Immediately update Quassel to version 0.12.2 or later. If an update is not possible, restrict access to the Quassel server to trusted networks only.
