CVE Alert: CVE-2025-11660 – ProjectsAndPrograms – School Management System

Risk verdict

High risk due to unauthenticated unrestricted file upload with a public exploit; exploitation could lead to remote code execution and impact availability.

Why this matters

The flaw enables arbitrary file uploads via a web-accessible endpoint, potentially allowing attackers to run code, deface or take down the platform, and access or modify student data. In school management deployments, this can enable persistence, disruption of admissions/grades workflows, and exposure of confidential information.

Most likely attack path

An unauthenticated actor targets /assets/uploadSllyabus.php, submitting crafted payloads that bypass validation. With restricted or no access controls, the attacker gains file upload capability, which could be abused to achieve code execution or resource manipulation, followed by potential lateral movement within the app’s modules.

Who is most exposed

Institutions hosting the School Management System on internet-facing infrastructure (including shared hosting or public cloud) are at highest risk, especially where upload handlers are not tightly sandboxed or isolated from web root.

Detection ideas

• Alerts for uploads to /assets/uploadSllyabus.php, especially executable file types.
• Files written in the web-accessible upload directory with php/js/sh extensions or suspicious filenames.
• Unusual spikes in upload volume or file sizes from unauthenticated sources.
• Logs showing failed/altered upload parameters or bypass attempts.
• Unexpected web server behavior after upload attempts (classical RCE indicators).

Mitigation and prioritisation

• Patch or upgrade to vendor-provided fix; if rolling releases obscure versioning, apply any available security update and monitor advisories.
• Disable unrestricted uploads; implement allow-list of file types and server-side validation; store uploads outside the web root and restrict script execution in the uploads directory.
• Enforce authentication and strict access controls for upload endpoints; require CSRF protection and user permission checks.
• Validate content and filenames; implement size/type checks and content scanning before acceptance.
• Deploy WAF rules and enable file integrity monitoring; schedule a tested change window for deployment and rollback plans.
