Descriptions

A command injection vulnerability exists in IGEL OS versions prior to 11.04.270 within the Secure Terminal and Secure Shadow services. The flaw arises due to improper input sanitization in the handling of specially crafted PROXYCMD commands on TCP ports 30022 and 5900. An unauthenticated attacker with network access to a vulnerable device can inject arbitrary commands, leading to remote code execution with elevated privileges. NOTE: IGEL OS v10.x has reached end-of-life (EOL) status.

Existe una vulnerabilidad de inyección de comandos en versiones de IGEL OS anteriores a la 11.04.270 dentro de los servicios Secure Terminal y Secure Shadow. La falla surge debido a una depuración de entrada incorrecta al gestionar comandos PROXYCMD especialmente manipulados en los puertos TCP 30022 y 5900. Un atacante no autenticado con acceso de red a un dispositivo vulnerable puede inyectar comandos arbitrarios, lo que provoca la ejecución remota de código con privilegios elevados. NOTA: El sistema operativo IGEL v10.x ha alcanzado el fin de su ciclo de vida (EOL).
