Summary

CVE-2020-37090 is a high-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Arox School Erp Pro. Its CVSS base score is 8.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 48% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and SI-3 (Malicious Code Protection) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

School ERP Pro 1.0 suffers from a file upload vulnerability in its messaging system, classified as CVE-2020-37090 and mapped to CWE-434 (Unrestricted Upload of File with Dangerous Type). The flaw allows authenticated users, such as students, to upload arbitrary PHP files through the message attachment feature. This leads to remote code execution (RCE) on the server, with a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity due to its network accessibility, low complexity, and lack of prerequisites.

Any remote attacker with network access can exploit this vulnerability without authentication privileges, as indicated by the CVSS metrics. By uploading a malicious PHP script via the messaging attachment, the attacker gains the ability to execute arbitrary code on the server, potentially compromising confidentiality, integrity, and availability through full system control.

Advisories and references, including those from Exploit-DB (exploit 48392) and Vulncheck, document the vulnerability and provide proof-of-concept exploits demonstrating the RCE. Archived project pages on SourceForge and the vendor site (arox.in) highlight the affected School ERP Pro 1.0 software, but no specific patches or mitigations are detailed in the available information.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation of uploaded files in the messaging system to reject arbitrary PHP scripts and prevent RCE.

prevent

Restricts information inputs to safe file types only, blocking uploads of dangerous PHP files through message attachments.

preventdetect

Employs malicious code protection mechanisms to scan and block PHP shells in uploaded message attachments before execution.

detects

Configuration and acceptance testing verify that file-upload handling enforces allowed types and does not permit dangerous content to be stored or executed.

prevents

Secure-coding guidelines and security testing explicitly address restrictions on allowed file types and upload handling, reducing the risk that dangerous file uploads are accepted without validation.

prevents

Mandated testing for malicious content and known vulnerabilities reduces the likelihood that an outsourced component will contain or accept dangerous file types that could later be uploaded or executed.

mitigates

Application allow-listing and pre-use scanning of received files directly blocks the introduction of executable content that has not been vetted, eliminating the primary vector for unrestricted dangerous file uploads.
