A weakness has been identified in PHPGurukul Online Course Registration 3.1. This vulnerability affects unknown code of the file /check_availability.php. Executing a manipulation of the argument cid can lead to sql injection. It is possible to launch the attack remotely. The exploit has been made available to the public and could be used for attacks.
AnalysisAI
SQL injection in PHPGurukul Online Course Registration 3.1 allows unauthenticated remote attackers to manipulate the cid parameter in /check_availability.php to execute arbitrary SQL queries, potentially leading to unauthorized data access or modification. Publicly available exploit code exists, elevating real-world risk despite moderate CVSS scoring.
Technical ContextAI
PHPGurukul Online Course Registration is a PHP-based educational management application. The vulnerability stems from improper input validation on the cid (course ID) parameter passed to the /check_availability.php endpoint. The application fails to sanitize or parameterize SQL query construction, allowing an attacker to inject arbitrary SQL syntax. CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component) indicates the root cause is insufficient encoding or escaping of user-supplied data before incorporation into SQL statements. The attack surface is direct HTTP/HTTPS access to the affected PHP file with no authentication required, making exploitation trivial.
RemediationAI
Apply a patched version of PHPGurukul Online Course Registration once released by the vendor. As a primary mitigation, implement parameterized queries (prepared statements) for all SQL operations, particularly in /check_availability.php. Validate and whitelist the cid parameter to accept only numeric course IDs; reject or sanitize any non-numeric input before database operations. Apply Web Application Firewall rules to detect and block SQL injection payloads in the cid parameter. Monitor for suspicious database query patterns.
