CVE-2025-50868 is a SQL Injection vulnerability identified in the takeassessment2.php file of the CloudClassroom-PHP-Project version 1.0. The vulnerability arises because the Q4 POST parameter is not properly sanitized before being incorporated into SQL queries. This lack of input validation allows an attacker to inject malicious SQL code, potentially manipulating the backend database. SQL Injection vulnerabilities can enable attackers to retrieve, modify, or delete sensitive data, bypass authentication mechanisms, or execute administrative operations on the database. Since the vulnerability is located in a PHP project related to a classroom or educational platform, it likely handles sensitive user data such as student records, assessments, and possibly authentication credentials. The absence of a CVSS score and patch links indicates that this vulnerability is newly published and may not yet have an official fix or widespread exploitation. Additionally, there are no known exploits in the wild at this time. However, the presence of an unsanitized POST parameter in a web application is a critical security flaw that can be exploited remotely without authentication, given that the vulnerable endpoint is accessible. The lack of detailed affected versions beyond 1.0 suggests that the vulnerability may be limited to that release or that further version information is not yet available. Overall, this vulnerability represents a significant risk to the confidentiality, integrity, and availability of the affected system's data and services.

For European organizations using CloudClassroom-PHP-Project 1.0 or derivatives thereof, this SQL Injection vulnerability poses a serious threat. Exploitation could lead to unauthorized access to sensitive educational data, including personal information of students and staff, assessment results, and potentially login credentials. This could result in data breaches violating GDPR and other privacy regulations, leading to legal penalties and reputational damage. Furthermore, attackers could alter or delete assessment data, undermining the integrity of educational processes. The availability of the platform could also be impacted if attackers execute destructive SQL commands or cause database corruption. Given the educational sector's increasing reliance on digital platforms, such an attack could disrupt learning activities and administrative operations. The lack of known exploits currently reduces immediate risk, but the vulnerability's nature means it could be targeted by opportunistic attackers or incorporated into automated scanning tools. European organizations must therefore treat this vulnerability with high priority to prevent potential exploitation and compliance violations.

To mitigate this vulnerability, organizations should immediately review and update the takeassessment2.php file to implement proper input validation and sanitization for the Q4 POST parameter. Specifically, parameterized queries or prepared statements should be used to prevent SQL Injection. If possible, upgrade to a patched version of CloudClassroom-PHP-Project once available. In the interim, web application firewalls (WAFs) can be configured to detect and block SQL Injection attempts targeting this endpoint. Conduct thorough code audits of related PHP files to identify and remediate similar injection flaws. Additionally, implement strict access controls and monitor database and application logs for suspicious activities indicative of exploitation attempts. Educate developers on secure coding practices to prevent recurrence. Finally, ensure regular backups of databases to enable recovery in case of data tampering or loss.
