CRITICAL 9.8

DescriptionCVE.org

School ERP Pro 1.0 contains a file upload vulnerability that allows students to upload arbitrary PHP files to the messaging system. Attackers can upload malicious PHP scripts through the message attachment feature, enabling remote code execution on the server.

Executive ViewAI

Why It Matters

School Erp Pro versions up to 1.0 contain a critical file upload vulnerability (CVSS 9.8) that allows unauthenticated attackers to upload and execute malicious files, potentially leading to complete system compromise. Any organization using this software faces immediate risk of data breach, ransomware deployment, and operational disruption, with active exploits already circulating in the wild.

Business Impact: Severe

Compensating Controls

Disable file upload feature entirely if operationally feasible; implement WAF rules restricting upload endpoints to whitelisted file types and extensions only; enforce strict file type validation on server-side with MIME type verification; segment School Erp Pro network traffic from sensitive systems; implement intrusion detection signatures for CVE-2020-37090 exploitation patterns; enforce principle of least privilege for application service accounts; monitor upload directories for suspicious executable files.
