CVE-2026-22221

Estado: ModificadaAlta (8.5)—

An OS Command Injection vulnerability in TP-Link Archer BE230 v1.2(vpn modules) and BE3600 v1 allows adjacent

authenticated

attacker

execute arbitrary code. Successful exploitation could allow an attacker to gain full administrative control of the device, resulting in severe compromise of configuration integrity, network security, and service availability.

This CVE covers one of multiple distinct OS command injection issues identified across separate code paths. Although similar in nature, each instance is tracked under a unique CVE ID.

This issue affects Archer BE230 v1.2 < 1.2.4 Build 20251218 rel.70420.

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

ExplotaciónT1210 Exploitation of Remote Serviceslateral movement90 %
Impacto principalT1059 Command and Scripting Interpreterexecution95 %
Impacto secundarioT1068 Exploitation for Privilege Escalationprivilege escalation85 %

Inyección de comandos OS en servicio remoto (firmware TP-Link) requiere privilegios (PR:H) y acceso de red adyacente (AV:A), encajando T1210. El impacto primario es ejecución arbitraria de código (T1059); secundario, acceso administrativo total (T1068).

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.
