Lifecycle Timeline
7DescriptionCVE.org
A weakness has been identified in SourceCodester Advanced School Management System 1.0. The affected element is an unknown function of the file commonController.php of the component checkEmail Endpoint. This manipulation causes sql injection. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks.
AnalysisAI
SQL injection in SourceCodester Advanced School Management System 1.0 allows remote unauthenticated attackers to execute arbitrary SQL queries via the checkEmail endpoint in commonController.php, potentially exposing or modifying database contents. Publicly available exploit code exists and the vulnerability requires only network access with no authentication, making it a practical exploitation risk for exposed instances.
Technical ContextAI
The vulnerability exists in the checkEmail endpoint handled by commonController.php in a PHP-based school management application. The root cause is CWE-89 (SQL Injection), indicating unsanitized user input is directly concatenated into SQL queries without parameterized statements or prepared queries. The CVSS 4.0 vector specifies AV:N (network-accessible) and PR:N (no privileges required), confirming the injectable input arrives via remote HTTP requests. The affected product is identified via CPE as SourceCodester Advanced School Management System version 1.0 and potentially later versions.
RemediationAI
Upgrade SourceCodester Advanced School Management System to a patched version released by the vendor; check https://www.sourcecodester.com/ for security advisories and available updates. Until a vendor patch is available, implement the following compensating controls: (1) Disable or restrict network access to the checkEmail endpoint by applying a Web Application Firewall (WAF) rule that blocks HTTP requests to commonController.php with checkEmail parameters from untrusted networks; (2) Deploy input validation at the application layer by enforcing strict email format validation (regex or library-based) before any database query and reject non-conforming input; (3) Implement parameterized queries (prepared statements) in the checkEmail function to prevent SQL concatenation - this requires code modification by the vendor or experienced system administrator; (4) Apply database-level principle of least privilege, ensuring the application database user has read-only access to non-sensitive tables and no DDL/DML permissions on critical tables. Each mitigation has trade-offs: WAF rules may cause false positives on legitimate requests; input validation alone does not eliminate SQL injection if attackers bypass format checks; code modification requires development resources.
