CVE-2025-11658 is a vulnerability found in the ProjectsAndPrograms School Management System, specifically in an unknown function within the /assets/changeSllyabus.php file. The flaw allows an attacker to manipulate the 'File' argument to perform unrestricted file uploads remotely without requiring authentication or user interaction. This means an attacker can upload arbitrary files, including potentially malicious scripts, which could lead to remote code execution, data compromise, or disruption of service. The product follows a rolling release model, which means updates are continuously delivered without traditional versioning, making it harder to identify affected versions or confirm patch availability. The vulnerability has a CVSS 4.0 score of 6.9, indicating a medium severity level. The attack vector is network-based, with low attack complexity and no privileges or user interaction needed. The impact on confidentiality, integrity, and availability is limited but still significant enough to warrant attention. No known exploits have been reported in the wild yet, but the exploit code is publicly available, increasing the risk of future attacks. The vulnerability primarily affects educational institutions using this system, potentially exposing sensitive student and staff data or allowing attackers to disrupt school operations.

For European organizations, particularly educational institutions using the ProjectsAndPrograms School Management System, this vulnerability poses a risk of unauthorized system access and data breaches. Attackers could upload web shells or malware, leading to remote code execution, data theft, or ransomware deployment. This could disrupt school operations, compromise student and staff personal data, and damage institutional reputation. Given the critical role of education infrastructure, exploitation could also have broader societal impacts. The rolling release nature of the software complicates patch management, potentially delaying remediation. Organizations lacking robust monitoring and filtering controls are at higher risk. The medium severity rating suggests that while the vulnerability is serious, it may not lead to widespread catastrophic failures, but targeted attacks could still cause significant harm. Compliance with European data protection regulations such as GDPR could be jeopardized if sensitive data is exposed.

1. Implement strict server-side validation on all file uploads, ensuring only allowed file types and sizes are accepted. 2. Employ whitelist-based filtering rather than blacklist approaches to prevent malicious file uploads. 3. Restrict upload directories with proper permissions and isolate them from executing code. 4. Deploy web application firewalls (WAFs) with custom rules to detect and block suspicious upload attempts targeting /assets/changeSllyabus.php. 5. Monitor logs and network traffic for unusual activity related to file uploads. 6. Conduct regular security audits and penetration testing focusing on file upload functionalities. 7. Engage with the vendor or community to obtain patches or updates addressing this vulnerability promptly. 8. Use intrusion detection/prevention systems (IDS/IPS) to identify exploitation attempts. 9. Educate IT staff and administrators about this vulnerability and the importance of timely mitigation. 10. Consider implementing application-level authentication and authorization controls around upload endpoints if feasible.
