Sources and claim methodology

Upstream source description

Guardian language-system passes the id GET parameter directly into an unsanitized SQL query in job_info_get.php (line 16): SELECT * FROM jobs where input1 = '\".$_GET['id'].\"'. An authenticated attacker can perform error-based SQL injection to extract database contents.
