Descriptions
TP-Link Omada ER605 PPTP VPN username Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link Omada ER605 routers. Authentication is not required to exploit this vulnerability. However, devices are only vulnerable if configured to use a PPTP VPN with LDAP authentication. The specific flaw exists within the handling of the username parameter provided to the /usr/bin/pppd endpoint. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-22446.
Vulnerabilidad de ejecución remota de código de inyección de comando de nombre de usuario de TP-Link Omada ER605 PPTP VPN. Esta vulnerabilidad permite a atacantes adyacentes a la red ejecutar código arbitrario en las instalaciones afectadas de los enrutadores TP-Link Omada ER605. No se requiere autenticación para aprovechar esta vulnerabilidad. Sin embargo, los dispositivos sólo son vulnerables si están configurados para usar una VPN PPTP con autenticación LDAP. La falla específica existe en el manejo del parámetro de nombre de usuario proporcionado al endpoint /usr/bin/pppd. El problema se debe a la falta de validación adecuada de una cadena proporcionada por el usuario antes de usarla para ejecutar una llamada al sistema. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de la raíz. Era ZDI-CAN-22446.
