Executive brief
A security vulnerability exists in the itsourcecode Online House Rental System, a web application used for managing property rentals. An attacker can exploit a flaw in the login process to gain unauthorized access to the underlying database. This could lead to the theft of sensitive user information, data tampering, or a complete takeover of the system.
Technical details
A SQL injection vulnerability exists in the '/ajax.php' file of the Online House Rental System 1.0. The root cause is the failure to sanitize or validate the 'username' parameter when the 'action=login' function is called. A remote, unauthenticated attacker can supply malicious SQL commands (including boolean-based, error-based, and time-based blind payloads) to manipulate database queries. Successful exploitation allows for unauthorized database access, sensitive data exfiltration, and potential administrative bypass. No patch is currently documented, but remediation involves implementing prepared statements and parameterized queries.
