CVE-2026-12850

Estado: AplazadaCrítica (9.1)—

Multiple OS command injection vulnerabilities exist in the libNetSetObj.so functionality of GeoVision GV-I/O Box 4E 2.09. A specially crafted network packet can lead to command execution. An attacker can send a network request to trigger this vulnerability.

`libNetSetObj.so` is an internal library used by various binaries on the device to configure the network stack (start and stop various services, configure IP, Netmask, gateway, dns, etc.)

#### CNetSetObj::m_F_n_Set_Gate_way command injection

The following function takes a string as a gatewy address, performs no sanitization on it and calls `system`. This is a classic command injection vulnerability. The function is reachable from both the network-exposed `DVRSearch` service and the `Network.cgi` endpoint.

      return 1;

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.

Inyección de comandos OS en servicio de red remoto (DVRSearch, Network.cgi) accesible con privilegios altos (PR:H). El parámetro 'gw' se pasa sin sanitizar a system(), permitiendo ejecución de comandos arbitrarios en contexto de root.

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.
