Detailsinfo

A vulnerability classified as critical has been found in Simple E-Document up to 3.1. This affects some unknown functionality of the component Cookie Header Handler. The manipulation with an unknown input leads to a unrestricted upload vulnerability. CWE is classifying the issue as CWE-434. The product allows the attacker to upload or transfer files of dangerous types that can be automatically processed within the product's environment. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

An unrestricted file upload vulnerability exists in Simple E-Document versions 3.0 to 3.1 that allows an unauthenticated attacker to bypass authentication by sending a specific cookie header (access=3) with HTTP requests. The application’s upload mechanism fails to restrict file types and does not validate or sanitize user-supplied input, allowing attackers to upload malicious .php scripts. Authentication can be bypassed entirely by supplying a specially crafted cookie (access=3), granting access to the upload functionality without valid credentials. If file uploads are enabled on the server, the attacker can upload a web shell and gain remote code execution with the privileges of the web server user, potentially leading to full system compromise.
