CVE-2026-97882 in CloudClassroom-PHP-Project
Summary
by MITRE • 09/25/2026
A weakness has been identified in mathurvishal CloudClassroom-PHP-Project up to 5dadec098bfbbf3300d60c3494db3fb95b66e7be. The impacted element is an unknown function of the file loginlinkfaculty.php of the component Faculty Authentication. Executing a manipulation of the argument fid/pass can lead to sql injection. It is possible to launch the attack remotely. The exploit has been made available to the public and could be used for attacks. This product takes the approach of rolling releases to provide continious delivery. Therefore, version details for affected and updated releases are not available. The vendor was contacted early about this disclosure but did not respond in any way.

The identified vulnerability resides within the Faculty Authentication component of the mathurvishal CloudClassroom-PHP-Project, specifically affecting versions up to commit 5dadec098bfbbf3300d60c3494db3fb95b66e7be. The core technical flaw is located in an unknown function within the loginlinkfaculty.php file, where user-supplied input from the fid and pass arguments is processed without adequate sanitization or parameterization. This lack of proper input validation allows for a SQL injection attack vector, classified under CWE-89 as Improper Neutralization of Special Elements used in an SQL Command. The vulnerability enables an attacker to manipulate these specific parameters to inject arbitrary SQL code into the backend database queries executed by the application.
From an operational perspective, this flaw presents significant risks due to its remote exploitability. An unauthenticated or authenticated attacker can leverage this weakness over a network connection to interact directly with the underlying database management system. The consequences of successful exploitation are severe and align with several MITRE ATT&CK techniques. Specifically, the ability to extract data corresponds to T1005 Data from Local System, while the potential for modifying records relates to T1078 Valid Accounts if valid credentials can be forged or bypassed through authentication manipulation. Furthermore, depending on the database engine and configuration, this could potentially lead to remote code execution via functions such as INTO OUTFILE in MySQL, which would escalate the impact beyond data theft to full system compromise.
The context of this vulnerability is exacerbated by the development methodology employed by the vendor. The product utilizes a rolling release model for continuous delivery, meaning that version numbers are not static and do not provide clear indicators of affected versus patched states. This approach complicates patch management for administrators who rely on traditional version-based scanning tools to identify vulnerable instances. Additionally, the security posture is further weakened by the vendor's lack of responsiveness; despite being contacted early regarding this disclosure, no response or mitigation guidance was provided. Consequently, users are left without official patches or configuration recommendations from the source, increasing reliance on community-driven fixes or self-imposed mitigations.
To mitigate this risk in the absence of an official patch, immediate remediation steps should focus on input validation and query parameterization at the application layer. Developers must ensure that all inputs passed to the fid and pass arguments are strictly validated against expected formats and types before being incorporated into SQL queries. The most effective technical control is the implementation of prepared statements with bound parameters using PDO or MySQLi in PHP, which separates SQL logic from data input, thereby neutralizing injection attempts regardless of the content provided by an attacker. Additionally, deploying a Web Application Firewall can provide a layer of defense-in-depth by filtering malicious payloads based on known attack signatures related to SQL injection patterns.
Long-term resilience requires addressing both technical and procedural gaps. Administrators should restrict database user privileges to the principle of least privilege, ensuring that the account used by the web application does not have administrative rights or access to sensitive system tables. This limits the blast radius if an injection is successful. Furthermore, organizations using this software should monitor for new commits in the public repository as a proxy for potential fixes, given the rolling release nature and lack of version tags. Establishing direct communication channels with maintainers remains critical, although current vendor engagement has proven ineffective. Regular security audits focusing on authentication modules are recommended to identify similar flaws across other components that may share the same architectural weaknesses regarding input handling and database interaction practices.
