Technical details

A SQL injection vulnerability (CWE-89) exists in the MySQL CNID (Catalog Node ID) backend of Netatalk versions 3.1.0 through 4.4.2. The vulnerability stems from the improper interpolation of AFP-controlled filenames into SQL queries without sufficient sanitization or parameterization. An authenticated attacker with network access to the AFP service can provide specially crafted filenames to execute arbitrary SQL statements against the CNID database. This can result in unauthorized data retrieval, modification, or deletion within the database context. The issue is resolved in version 4.4.3.
