Estado: AplazadaAlta (7.8)—

Insecure permissions in the script /etc/init.d/lighttpd in AK-Nord USB-Server-LXL Firmware v0.0.16 Build 2023-03-13 allows a locally authenticated low-privilege user to execute arbitrary commands with root privilege via editing this script which is executed with root-privileges on any interaction and on every system boot.

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.

AV:L + PR:L sin UI permite escalada local editando script ejecutado como root (CWE-276: permisos inseguros). Impacto: modificación de permisos (T1222) y ejecución de comandos arbitrarios con root (T1059).

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.
