This flaw allows attackers to inject malicious SQL code, potentially leading to unauthorized data access and manipulation. The vulnerability affects versions 0 through 1.1 of the module, and a fix is available in version 1.2.
Successful exploitation of CVE-2025-4688 could grant an attacker complete control over the underlying database. This includes the ability to read, modify, or delete sensitive data such as exam results, user credentials, and potentially other application data. Depending on the database configuration and permissions, an attacker might also be able to execute arbitrary commands on the server hosting the SINAV.LINK Exam Result Module. The blast radius extends to any system or service that relies on the compromised database, potentially impacting the integrity and confidentiality of exam data and user information.
The vulnerability was publicly disclosed on 2025-09-16. No public proof-of-concept exploits are currently known, but the severity of the vulnerability (CVSS 9.8) suggests a high probability of exploitation.

The primary mitigation for CVE-2025-4688 is to immediately upgrade the SINAV.LINK Exam Result Module to version 1.2 or later. If upgrading is not immediately possible due to compatibility issues or system downtime constraints, consider implementing temporary workarounds such as input validation and parameterized queries to sanitize user-supplied data. Web application firewalls (WAFs) configured with rules to detect and block SQL injection attempts can also provide a layer of defense. After upgrading, confirm the vulnerability is resolved by attempting a SQL injection attack through the affected endpoints and verifying that the input is properly sanitized.
Update the SINAV.LINK Exam Result module to version 1.2 or higher. This version contains the fix for the SQL Injection vulnerability. The update can be performed through the module's administration panel or by downloading the latest version from the vendor.
