Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions Guardian language-system (affected versions not specified)

Description An unauthenticated attacker can perform error-based SQL injection by sending crafted values to the id parameter via a GET request to the 'job info.php' endpoint. The issue occurs because the application passes the id variable directly into an unsanitized SQL query, allowing for the extraction of the database version, current user, schema names, and table contents.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, restrict access to the 'job info.php' endpoint or avoid using the id parameter until the issue is resolved.
