An unauthenticated SQL injection vulnerability in Exam Form Submission 1.0 poses a significant risk to data integrity and system security.

This vulnerability is an SQL injection flaw (CWE-89) located in the /admin/delete_s7.php file. It allows an unauthenticated remote attacker to inject malicious SQL queries via the ID parameter.

The ability for an unauthenticated attacker to inject arbitrary SQL commands into the database can lead to unauthorized data access, modification, or deletion. Given the CVSS score of 7.3, this high-severity vulnerability represents a substantial risk of data compromise and potential loss of confidentiality or integrity within the application environment.

Immediate Action: As no official patch is available, administrators should immediately restrict access to the /admin/ directory using IP allowlisting or authentication proxies.

Proactive Monitoring: Monitor web server access logs for anomalous requests containing SQL syntax or suspicious characters directed at the delete_s7.php endpoint.

Compensating Controls: Implement a Web Application Firewall (WAF) with rules specifically configured to detect and block SQL injection patterns to provide a temporary virtual patch.

Public Exploit Available: Yes, a published proof-of-concept exists, as documented in the research write-up at the referenced GitHub repository.

The presence of a public proof-of-concept increases the urgency of securing this installation. Because a formal vendor patch is not currently available, administrators must prioritize the implementation of compensating controls such as WAF rules and network-level access restrictions to prevent unauthorized exploitation of this SQL injection vulnerability.
