Technical details

The vulnerability is a SQL injection in the searchPhrase parameter of the /ajax_table.php API endpoint, affecting multiple table processing includes. An authenticated remote attacker with normal user privileges can craft malicious input in the searchPhrase parameter to inject arbitrary SQL commands. The attack requires valid credentials but no special privileges, allowing extraction of all database contents. The vulnerability was patched in commit 32f72bc (July 10, 2020) which added input sanitization using parameterized queries to the affected parameters (searchPhrase, address, and sort).
