The Online Examination System 1.0 contains a critical SQL injection vulnerability that allows remote, unauthenticated attackers to interact with the underlying database.

This is a SQL injection vulnerability (CWE-89) located in the login.php file. The flaw permits an unauthenticated attacker to inject malicious SQL commands via the username or password parameters, potentially leading to unauthorized database access.

Successful exploitation of this SQL injection vulnerability could result in unauthorized access to sensitive user data stored within the examination system database. Given the CVSS score of 7.3, this represents a significant risk to data confidentiality and integrity, potentially leading to a complete compromise of the application user base.

Immediate Action: As no official patch is currently identified, administrators should restrict access to the login.php endpoint using network-level controls or consider disabling the application until a security update is provided by the vendor.

Proactive Monitoring: Security teams should review web server access logs for anomalous SQL syntax patterns, such as UNION, SELECT, or OR statements, within the username and password fields.

Compensating Controls: Deploy a Web Application Firewall (WAF) with rules configured to detect and block common SQL injection payloads targeting authentication forms.

Public Exploit Available: Unknown.

The presence of a remote, unauthenticated SQL injection vulnerability in an authentication component poses a high risk to the confidentiality of stored credentials and system data. Administrators are urged to monitor this product for vendor-supplied security patches and apply them immediately upon release. In the interim, isolating the affected system from public exposure is the most effective way to mitigate this risk.
