Technical details

A blind SQL injection vulnerability exists in Revive Adserver versions 6.0.6 and earlier within the 'zone-include.php' script. The root cause is the improper neutralization of special elements in the 'clientid' parameter, which is used in database queries without adequate sanitization (CWE-89). An attacker with low-privileged network access can exploit this flaw to perform blind SQL injection attacks. This could lead to unauthorized data retrieval, modification, or deletion within the database. The vendor has addressed this issue by improving input validation for all parameters processed by the affected script.

Affected products
