CVE-2020-36630Known exploitation

Database access via unsanitized pagination parameters

Published Dec 25, 2022 · Updated Aug 4, 2024

SQL injection in FreePBX CDR Reports 14.0 allows remote authenticated users to read or modify database tables through the UCP interface. The ajaxHandler function in ucp/Cdr.class.php passes request-supplied limit and offset values into CDR query construction without numeric filtering. A user must reach the authenticated UCP CDR grid, and successful injection exposes or changes FreePBX database records.
