persistent XSS through SQLi WeBid 1.0.2

An attacker could inject malicious HTML/JS through a SQL injection flow in the adsearch.php. The SQL injection flaw exists in the 'maxprice' field. The SQL injection attack cannot be elevated, so the attacker leverages the SQL injection to trigger an error that would write the malicious HTML/JS to the error log. The XSS attack happens when the admin or any user capable of viewing the error log from the ACP.

Mitigation:

Ensure that user input is properly sanitized and validated before being used in SQL queries.
