A vulnerability was found in PHPGurukul User Registration & Login and User Management System 3.3. It has been classified as critical. This affects an unknown part of the file /admin/manage-users.php. The manipulation of the argument ID leads to sql injection. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used.
AnalysisAI
SQL injection vulnerability in PHPGurukul User Registration & Login and User Management System 3.3 allows authenticated, low-privilege attackers to manipulate SQL queries via the ID parameter of /admin/manage-users.php. Public exploit code is available, but there is no evidence of active exploitation (not in CISA KEV). Exploitation can lead to unauthorized access, modification, or extraction of database contents, including user credentials.
Technical ContextAI
The flaw resides in a PHP-based user management framework where the /admin/manage-users.php endpoint fails to properly sanitize the ID input before including it in an SQL statement, leading to CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The affected product is identified by CPE cpe:2.3:a:phpgurukul:user_registration_\&_login_and_user_management_system:3.3:*:*:*:*:*:*:*. The underlying technology stack likely uses MySQL or similar relational database, and the injection occurs through an administrative interface that should only be accessible after authentication.
RemediationAI
No official patch has been released by the vendor. As a temporary workaround, restrict access to /admin/manage-users.php to trusted users only, deploy a Web Application Firewall (WAF) rule to detect and block SQL injection patterns targeting the ID parameter, and if source code is available, apply input sanitization using prepared statements or parameterized queries. Note that WAF rules may be bypassed by obfuscated payloads, and access restriction alone does not prevent abuse by legitimate authenticated users.
