Online Course Registration CVE-2025-11342

Apply input validation and parameterized queries to the coursecode parameter in /admin/edit-course.php. If a vendor patch is not available, implement immediate compensating controls: (1) Replace all SQL string concatenation with parameterized prepared statements (bind variables) using PHP Data Objects (PDO) or mysqli prepared statements-this eliminates SQL injection by separating query structure from user input, with minimal performance overhead. (2) Validate coursecode against a whitelist of allowed characters (e.g., alphanumeric and underscore only) before query execution, rejecting any input containing SQL metacharacters (single quotes, semicolons, double hyphens, parentheses). (3) Apply the principle of least privilege to the database user executing admin queries-create a dedicated read/write role for /admin/edit-course.php that lacks ALTER TABLE or CREATE USER permissions, preventing attackers from modifying schema or escalating privileges even if SQL injection succeeds. (4) Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the coursecode parameter (e.g., OWASP ModSecurity rules for SQL injection), though this is secondary to code-level fixes. Monitor admin account activity for unusual database query patterns. No vendor advisory with a specific patch version is documented; check code-projects.org and vuldb.com for updates.
