This critical vulnerability exists within the code-projects Exam Form Submission 1.0 application specifically in the /admin/delete_s7.php file where an insecure handling of the ID parameter creates a SQL injection flaw. The vulnerability allows remote attackers to execute arbitrary SQL commands by manipulating the ID argument, potentially leading to complete database compromise and unauthorized access to sensitive examination data. The exploitation of this vulnerability can result in data theft, data modification, or complete system takeover, making it particularly dangerous for educational institutions relying on this platform for exam management.
The technical implementation of this SQL injection vulnerability stems from improper input validation and sanitization within the delete_s7.php script. When user-supplied ID values are directly incorporated into SQL queries without proper parameterization or escaping mechanisms, attackers can inject malicious SQL code that bypasses authentication checks and executes unintended database operations. This flaw aligns with CWE-89 which specifically addresses SQL injection vulnerabilities, and represents a classic example of unsafe query construction where user input flows directly into database commands. The remote exploit capability means that attackers do not require physical access to the system and can target the vulnerability over network connections.
The operational impact of this vulnerability extends beyond simple data theft to encompass complete system compromise and potential denial of service conditions. Attackers could extract all examination records including student information, exam results, and administrative data, potentially violating privacy regulations and educational data protection standards. The vulnerability's classification as critical indicates that it can be exploited without authentication, making it particularly attractive to threat actors targeting educational institutions. This type of vulnerability also provides a potential foothold for further attacks within the network infrastructure, as compromised examination systems often contain sensitive information that can be leveraged for additional attacks.
Organizations utilizing this software should immediately implement mitigations including input validation, parameterized queries, and access controls to prevent exploitation of this vulnerability. The recommended approach involves implementing proper SQL query parameterization techniques to ensure that user input cannot alter the intended structure of database commands. Additionally, network segmentation and web application firewalls should be deployed to monitor and filter malicious traffic targeting this specific vulnerability. According to ATT&CK framework, this vulnerability maps to T1190 (Exploit Public-Facing Application) and T1071.005 (Application Layer Protocol: DNS) as attackers may use these techniques to probe and exploit the vulnerable system. Regular security assessments and patch management procedures should be enforced to prevent similar vulnerabilities from being introduced in future versions of the software.
