CVE-2026-40061

When BIG-IP DNS is provisioned, a vulnerability exists in an undisclosed iControl REST and BIG-IP TMOS Shell (tmsh) command that may allow an authenticated attacker with the Resource Administrator or Administrator role to execute arbitrary system commands with higher privileges. In Appliance mode deployments, a successful exploit can allow the attacker to cross a security boundary. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

Summary		(es) Cuando se aprovisiona BIG-IP DNS, existe una vulnerabilidad en un comando no revelado de iControl REST y BIG-IP TMOS Shell (tmsh) que puede permitir a un atacante autenticado con el rol de Administrador de Recursos o Administrador ejecutar comandos de sistema arbitrarios con privilegios más altos. En implementaciones en modo Appliance, un exploit exitoso puede permitir al atacante cruzar un límite de seguridad. Nota: Las versiones de software que han alcanzado el Fin del Soporte Técnico (EoTS) no se evalúan.
