File Upload Validation Bypass in MCO

Executive Summary

This vulnerability occurs because MCO does not properly validate the types of files that users upload. The file upload validation relies solely on client-side checks, which can be bypassed by an attacker.

As a result, an authorized user with low privileges can upload files of any type to the server, potentially leading to security risks.

Compliance Impact

The vulnerability in MyComplianceOffice (MCO) allows an authorized, low-privileged attacker to upload files with arbitrary types to the server due to insufficient server-side validation of uploaded files. This flaw could potentially lead to unauthorized data exposure or manipulation.

Since MCO is a compliance management platform used to help organizations meet regulatory obligations, such a vulnerability may undermine the integrity and security of compliance data, which is critical for standards like GDPR and HIPAA that require strict data protection and control measures.

However, the provided information does not explicitly state the direct impact of this vulnerability on compliance with specific regulations such as GDPR or HIPAA.
