CVE-2025-50867 describes a SQL Injection vulnerability in the CloudClassroom-PHP-Project version 1.0, specifically within the takeassessment2.php endpoint. The vulnerability arises because the Q5 POST parameter is directly embedded into SQL queries without any sanitization or parameterization. This lack of input validation allows an attacker to inject arbitrary SQL code, potentially manipulating the database queries executed by the application. Such exploitation can lead to unauthorized data access, data modification, or even complete compromise of the underlying database. Since the vulnerability is located in an endpoint related to assessments, it is likely part of an educational or e-learning platform. The absence of a CVSS score and known exploits in the wild suggests this vulnerability is newly disclosed and may not yet be widely exploited. However, the technical details confirm that the vulnerability is straightforward to exploit if an attacker can send crafted POST requests to the affected endpoint. The vulnerability does not require authentication or user interaction beyond sending a malicious POST request, increasing its risk profile. No patches or mitigations are currently linked, indicating that affected users must implement their own protective measures until an official fix is released.

For European organizations, especially educational institutions or companies using the CloudClassroom-PHP-Project platform, this vulnerability poses a significant risk. Exploitation could lead to unauthorized disclosure of sensitive student or assessment data, undermining privacy and compliance with GDPR. Additionally, attackers could alter assessment results or inject malicious data, compromising the integrity of educational records. If the database is further leveraged for authentication or other critical functions, the impact could extend to broader system compromise. The availability of the service could also be affected if attackers execute destructive SQL commands. Given the educational sector's importance in Europe and strict data protection regulations, such a vulnerability could result in reputational damage, regulatory fines, and operational disruption.

To mitigate this vulnerability, organizations should immediately audit the takeassessment2.php endpoint and any other input handling code for proper input validation and sanitization. Implementing prepared statements with parameterized queries is critical to prevent SQL injection. If immediate code changes are not feasible, deploying a Web Application Firewall (WAF) with rules to detect and block SQL injection attempts targeting the Q5 parameter can provide temporary protection. Organizations should also monitor logs for suspicious POST requests to this endpoint. Conducting a thorough security review of the entire CloudClassroom-PHP-Project codebase to identify and remediate similar vulnerabilities is advisable. Finally, organizations should engage with the software vendor or community to obtain patches or updates addressing this issue and plan for timely deployment once available.
