CVE-2025-11660 is a vulnerability identified in the ProjectsAndPrograms School Management System, specifically in the file /assets/uploadSllyabus.php. The issue arises from improper handling of the 'File' argument, allowing attackers to upload files without restrictions. This unrestricted upload vulnerability can be exploited remotely without any authentication or user interaction, making it highly accessible to attackers. The uploaded files could include malicious scripts or executables, potentially enabling remote code execution, data exfiltration, or disruption of services. The product uses a rolling release model, complicating version tracking and patch management, as affected or fixed versions are not clearly delineated. The CVSS 4.0 score of 6.9 (medium severity) reflects the network attack vector, low complexity, no privileges or user interaction required, and limited impact on confidentiality, integrity, and availability. Although no exploits are currently known in the wild, the public disclosure of the vulnerability increases the likelihood of exploitation attempts. The vulnerability is particularly concerning for educational institutions relying on this system to manage sensitive student and administrative data, as exploitation could lead to unauthorized access or system compromise.

For European organizations, especially educational institutions using the ProjectsAndPrograms School Management System, this vulnerability poses significant risks. Successful exploitation could lead to unauthorized access to sensitive student records, administrative data, and internal communications, impacting confidentiality. Attackers could also modify or delete data, affecting data integrity, or deploy malware that disrupts system availability, causing operational downtime. Given the remote and unauthenticated nature of the exploit, attackers can target these systems en masse, increasing the risk of widespread compromise. The rolling release nature of the software complicates patch management, potentially delaying remediation and prolonging exposure. Additionally, educational institutions are often targeted for espionage or ransomware attacks, making this vulnerability a potential vector for such threats. The impact extends beyond individual organizations to affect trust in educational services and compliance with data protection regulations such as GDPR.

To mitigate CVE-2025-11660, organizations should immediately audit and restrict file upload functionalities within the ProjectsAndPrograms School Management System. Specific steps include: 1) Implement strict server-side validation of uploaded files, including file type, size, and content inspection to prevent malicious payloads. 2) Employ allowlists for acceptable file extensions and reject all others. 3) Use secure storage locations for uploads, segregated from executable directories to prevent execution of uploaded files. 4) Apply web application firewalls (WAF) with rules to detect and block suspicious upload attempts. 5) Monitor logs for unusual upload activity or access patterns. 6) Engage with the vendor or community to identify patches or updates addressing this vulnerability, despite the rolling release model. 7) If patches are unavailable, consider temporary disabling or restricting the upload feature until a fix is applied. 8) Educate system administrators on the risks and signs of exploitation. 9) Regularly back up critical data and test restoration procedures to minimize impact of potential attacks. 10) Conduct penetration testing focusing on file upload mechanisms to validate defenses.
