CVE-2013-10038

Estado: AplazadaCrítica (9.3)—

An unauthenticated arbitrary file upload vulnerability exists in FlashChat versions 6.0.2 and 6.0.4 through 6.0.8. The upload.php endpoint fails to properly validate file types and authentication, allowing attackers to upload malicious PHP scripts. Once uploaded, these scripts can be executed remotely, resulting in arbitrary code execution as the web server user.

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.

Vulnerabilidad de carga de archivos sin autenticación en endpoint web (T1190). Permite subir PHP malicioso ejecutable como web shell (T1505.003) con ejecución remota de código (T1059) en contexto del usuario del servidor.

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.
