Technical Analysis
This vulnerability in SourceCodester Class and Exam Timetabling System 1.0 arises from improper sanitization of the ID parameter in the /delete_user.php script, leading to SQL injection. An attacker can remotely manipulate the ID argument to execute arbitrary SQL commands on the backend database. The vulnerability is confirmed publicly with exploit code available, increasing the risk of exploitation. No official patch or remediation information is provided in the available data.
Potential Impact
Successful exploitation could allow an unauthenticated remote attacker to execute arbitrary SQL queries on the backend database. This may lead to unauthorized data access, modification, or deletion depending on the database privileges. The vulnerability impacts confidentiality, integrity, and availability of the affected system's data to a limited extent as indicated by the CVSS vector components.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, it is recommended to apply input validation and parameterized queries to the ID parameter in /delete_user.php to prevent SQL injection. Monitor for unusual database activity and restrict database user privileges where possible.
