CVE-2014-2321

Estado: ModificadaAlta (10)—💥 Exploit

web_shell_cmd.gch on ZTE F460 and F660 cable modems allows remote attackers to obtain administrative access via sendcmd requests, as demonstrated by using "set TelnetCfg" commands to enable a TELNET service with specified credentials.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
