Summary
CloudClassroom PHP Project contains a SQL injection weakness in makeresult.php, where the makeid argument may influence a database query without adequate separation from SQL syntax. A remote attacker may exploit this condition to read, modify, or otherwise interact with database data when the affected endpoint is accessible.
Affected context
The vulnerability occurs in deployments of CloudClassroom PHP Project versions represented by the affected continuous-delivery revision when makeresult.php processes the makeid parameter. Risk is higher when the endpoint is remotely reachable and user-controlled input is incorporated into database operations without reliable parameterization or equivalent safeguards. Because the product uses rolling releases, exact affected and remediated version boundaries may not be available.
Exploit preconditions
- Attack surface: The remotely accessible makeresult.php endpoint - Required access: The ability to send requests to the affected application;
authentication requirements depend on deployment configuration
- Trigger point: Processing of the makeid argument - Why exploitation is possible: Input may be interpreted as part of a
database statement rather than strictly as application data
Why this happens
The underlying bug is a failure to maintain a strict separation between untrusted request data and SQL commands. When the makeid value is assembled into a query or passed through insufficient filtering, database syntax may be influenced by the requester. This maps primarily to CWE-89, SQL Injection, and is also related to CWE-74, improper neutralization of special elements in an output used by a downstream component.
Potential impact
- An attacker may retrieve sensitive records from the application database.
- An attacker could alter, insert, or delete database content, depending on
query privileges.
- Database availability may be affected through destructive or expensive
operations.
- Compromised data could enable account abuse, privacy violations, or
follow-on attacks against connected services.
General mitigation guidance
Mitigation generally centers on using parameterized queries or prepared statements for every database operation involving request data. Input handling can reduce trust by applying allowlisted formats and type checks, but validation should complement rather than replace query parameterization. Database accounts should use least privilege, with separate restricted identities for application functions where practical. Secure-by-default data-access libraries, centralized query helpers, and consistent error handling can further reduce injection risk without exposing database details.
How teams detect issues like this
Detection may include static analysis for string concatenation or interpolation of request parameters into SQL, review of database calls in makeresult.php, and checks that prepared statements bind values with appropriate types. Code review should treat direct use of request parameters in query-building paths as a security signal. Runtime monitoring can examine unusual database errors, query patterns, and access to unexpected records, while CI policy enforcement and automated code-review tools may help identify unsafe data-access patterns.
