This vulnerability resides within the lavkush-maurya Student-Registration-System version 1.0, specifically targeting the /student/changepass.php file where an unknown function processes user input. The flaw manifests through improper sanitization of the oldpass parameter, creating a pathway for malicious actors to inject arbitrary SQL commands into the database query execution flow. This represents a classic sql injection vulnerability that allows attackers to manipulate the underlying database structure and potentially extract sensitive information from the system.
The technical implementation of this vulnerability follows established patterns where user-supplied input flows directly into sql query construction without proper parameterization or input validation mechanisms. When an attacker manipulates the oldpass argument, the application fails to properly escape or bind the input value, enabling the injection of malicious sql payloads that can execute with the privileges of the database user account. This vulnerability classifies under CWE-89 sql injection according to the common weakness enumeration framework and aligns with attack techniques described in the mitre ATT&CK framework under T1190 for exploitation of remote services.
The operational impact of this vulnerability extends beyond simple data exfiltration, as it provides attackers with potential access to student records, personal information, and other sensitive academic data stored within the system. Remote exploitation capabilities mean that attackers can leverage this vulnerability from any network location without requiring physical access to the target system, making it particularly dangerous for web-based applications. The fact that the exploit has been publicly disclosed increases the risk profile significantly as malicious actors can immediately utilize documented attack vectors.
Mitigation strategies should focus on implementing proper input validation and parameterized queries throughout the application codebase, specifically addressing the vulnerable function in changepass.php. Database access controls should be reviewed to ensure least privilege principles are enforced, limiting the potential damage from successful exploitation attempts. Additionally, regular security audits and penetration testing should be conducted to identify similar vulnerabilities within the application's code structure. The vendor's lack of response to early disclosure raises concerns about the overall security posture of the system and suggests that organizations relying on this software should consider immediate remediation efforts or alternative solutions to protect their data assets.
