CVE-2025-51567 identifies a SQL Injection vulnerability in the Kashipara Online Exam System version 1.0, specifically in the /exam/user/profile.php endpoint. The vulnerability arises because the application fails to properly sanitize or parameterize user-supplied input in POST parameters including rname, rcollage, rnumber, rgender, and rpassword. An attacker can exploit this flaw by crafting malicious SQL statements within these parameters, which the backend database executes. This can lead to unauthorized access to the database, allowing attackers to read, modify, or delete sensitive data such as user profiles, exam results, or credentials. The vulnerability does not require prior authentication, making it remotely exploitable by any attacker with network access to the web application. No patch or fix is currently referenced, and no public exploits have been reported yet. The lack of CVSS score suggests this is a newly disclosed vulnerability. SQL Injection remains one of the most critical web application vulnerabilities due to its potential to compromise confidentiality, integrity, and availability of data. The affected system being an online exam platform increases the risk to educational data and system trustworthiness.

For European organizations, particularly educational institutions using the Kashipara Online Exam System or similar platforms, this vulnerability poses a significant risk. Exploitation could lead to unauthorized disclosure of personal student information, exam results, and potentially administrative credentials. This compromises confidentiality and integrity, undermining trust in the examination process. Data tampering could invalidate exam results or disrupt exam operations, impacting availability. The breach of sensitive educational data could also lead to regulatory non-compliance under GDPR, resulting in legal and financial penalties. Furthermore, attackers could leverage database access to pivot into broader network attacks. The impact is heightened in countries with large-scale digital education deployments or where remote examination systems are critical due to ongoing digital transformation in education.

Immediate mitigation should focus on implementing robust input validation and sanitization for all user-supplied data, especially the POST parameters identified. Developers must refactor the vulnerable code to use parameterized queries or prepared statements to prevent SQL Injection. Conduct a thorough code audit of the entire application to identify and remediate similar injection points. Employ Web Application Firewalls (WAFs) with SQL Injection detection rules as a temporary protective measure. Regularly update and patch the application once an official fix is released. Additionally, implement strict access controls and monitor database logs for suspicious queries. Educate developers on secure coding practices and conduct penetration testing to validate the effectiveness of mitigations. Backup critical data regularly to enable recovery in case of compromise.
