CVE-2025-0425

Estado: AplazadaAlta (8.5)—

An attacker is able to escalate his privileges to "nt authority\system" on the Windows client running the "bestinformed Infoclient".

This attack is not possible if a custom configuration ("Infoclient.ini") containing the flags "ShowOnTaskbar=false" or "DisabledItems=stPort,stAddress" is deployed.

Detalles técnicos trazas, registros y código del informe original
Via the GUI of the "bestinformed Infoclient", a low-privileged user is by default able to change the server address of the "bestinformed Server" to which this client connects. This is dangerous as the "bestinformed Infoclient" runs with elevated permissions ("nt authority\system"). By changing the server address to a malicious server, or a script simulating a server, the user is able to escalate his privileges by abusing certain features of the "bestinformed Web" server. Those features include:
  *  Pushing of malicious update packages
  *  Arbitrary Registry Read as "nt authority\system"

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 escalada de privilegios local (AV:L, PR:L, VC:H). Un usuario sin privilegios modifica la dirección del servidor para recibir paquetes de actualización maliciosos (T1195.002) y lee registro del sistema como SYSTEM (T1012).

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.
