Summary

CVE-2020-37084 is a high-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Arox School Erp Pro. Its CVSS base score is 8.6 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 47% 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 CM-7 (Least Functionality) — see the control section below for these in your framework.

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

CVE-2020-37084 is a remote code execution vulnerability affecting School ERP Pro 1.0. The flaw arises from improper file validation in the pre-editstudent.inc.php component, which allows authenticated admin users to upload arbitrary PHP files as profile photos by bypassing file extension checks. It is associated with CWE-434 (Unrestricted Upload of File with Dangerous Type) and carries a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).

An authenticated administrator can exploit this vulnerability remotely with low attack complexity and no user interaction required. Successful exploitation enables the attacker to execute arbitrary code on the server, potentially leading to full compromise of the affected system with high impacts on confidentiality, integrity, and availability.

Advisories and exploit details are available in provided references, including an Exploit-DB entry (48392) demonstrating the profile photo upload for RCE and a Vulncheck advisory on the School ERP Pro admin profile photo upload vulnerability. Archived project pages from SourceForge and arox.in are also referenced, though no specific patches or mitigation steps are detailed in the CVE information.

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly enforces validation of file content and type on upload, blocking the arbitrary PHP file bypass in pre-editstudent.inc.php.

preventdetect

Requires malicious-code scanning and blocking of uploaded files before they can be stored or executed as profile photos.

prevent

Restricts system functionality to prohibit execution of uploaded scripts or storage of dangerous file types in web directories.

Hardened configuration baselines can enforce allowed file types and processing rules.

Secure development practices include input validation and file-type restrictions that prevent this weakness.

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.
