CVE-2025-5196

Estado: AnalizadaAlta (7.5)—

A vulnerability has been found in Wing FTP Server up to 7.4.3 and classified as critical. Affected by this vulnerability is an unknown functionality of the component Lua Admin Console. The manipulation leads to execution with unnecessary privileges. The attack can be launched remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. Upgrading to version 7.4.4 is able to address this issue. It is recommended to upgrade the affected component. The vendor explains: "[W]e do not consider it as a security vulnerability, because the system admin in WingFTP has full permissions [...], but you can suggest the user run WingFTP service as Normal User rather than SYSTEM/Root, it will be safer."

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.

Vector CVSS muestra AV:N (remoto) con PR:H (requiere privilegios altos), indicativo de T1210. El impacto es escalada mediante ejecución con privilegios innecesarios en Lua Admin Console.

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.
