CVE-2014-125126

Estado: AplazadaCrítica (9.2)—

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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Aplicación web expuesta sin autenticación (cookie bypass) permite carga de archivos PHP sin restricciones (CWE-434), ejecutable por el servidor web (T1059) y potencial shell web (T1505.003) con acceso remoto no autenticado (T1078).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
