CVE-2025-11658 identifies a vulnerability in the ProjectsAndPrograms School Management System, specifically in an unknown function within the /assets/changeSllyabus.php file. The vulnerability arises from improper handling of the 'File' argument, allowing unrestricted file uploads without authentication or user interaction. This flaw enables remote attackers to upload arbitrary files, which could lead to remote code execution, data manipulation, or denial of service. The product's rolling release model means that affected and patched versions are not distinctly versioned, complicating patch management and vulnerability tracking. The CVSS 4.0 score of 6.9 reflects a medium severity, with network attack vector, low complexity, no privileges or user interaction required, and limited impact on confidentiality, integrity, and availability. Although no active exploits are reported in the wild, the public availability of exploit code increases the likelihood of attacks. The vulnerability poses a significant risk to educational institutions relying on this system, as attackers could compromise sensitive student and staff data or disrupt school operations.

For European organizations, particularly educational institutions using the ProjectsAndPrograms School Management System, this vulnerability could lead to unauthorized access and control over critical systems. Attackers could upload malicious scripts or executables, potentially resulting in data breaches involving personal student information, alteration or deletion of academic records, and disruption of school services. The compromise of such systems could also facilitate lateral movement within networks, increasing the risk of broader organizational impact. Given the sensitive nature of educational data and regulatory requirements such as GDPR, exploitation could result in significant legal and reputational consequences. The rolling release nature of the software may delay detection and remediation, increasing exposure time. Additionally, the lack of authentication and user interaction requirements lowers the barrier for attackers, making European schools attractive targets for cybercriminals or state-sponsored actors aiming to disrupt education infrastructure.

Organizations should immediately implement strict server-side validation of uploaded files, including enforcing file type restrictions, size limits, and scanning for malware. Employing allowlists for permitted file extensions and verifying file contents beyond extensions is critical. Disabling direct execution permissions on upload directories can prevent execution of malicious files. Implementing web application firewalls (WAFs) to detect and block suspicious upload attempts is recommended. Regularly monitoring logs for unusual upload activity and conducting security audits of the affected endpoint are essential. Given the rolling release model, organizations should engage directly with the vendor to obtain the latest security patches or hotfixes and apply them promptly. Network segmentation can limit the impact of a compromised system. Additionally, educating staff about the risks and ensuring backups of critical data are maintained will aid in recovery if exploitation occurs.
