Descriptions

A vulnerability in the build procedure for certain executable system files installed at boot time on Cisco Application Policy Infrastructure Controller (APIC) devices could allow an authenticated, local attacker to gain root-level privileges. The vulnerability is due to a custom executable system file that was built to use relative search paths for libraries without properly validating the library to be loaded. An attacker could exploit this vulnerability by authenticating to the device and loading a malicious library that can escalate the privilege level. A successful exploit could allow the attacker to gain root-level privileges and take full control of the device. The attacker must have valid user credentials to log in to the device. Cisco Bug IDs: CSCvc96087. Known Affected Releases: 1.1(0.920a), 1.1(1j), 1.1(3f); 1.2 Base, 1.2(2), 1.2(3), 1.2.2; 1.3(1), 1.3(2), 1.3(2f); 2.0 Base, 2.0(1).

Una vulnerabilidad en el procedimiento de construcción para ciertos archivos del sistema ejecutables instalados en el tiempo de arranque en dispositivos Cisco Application Policy Infrastructure Controller (APIC) podría permitir que un atacante local autenticado obtuviese privilegios de nivel root. Esta vulnerabilidad se debe a un archivo del sistema ejecutable personalizado que ha sido construido para usar rutas de búsqueda relativas para librerías sin validar correctamente la librería que se va a cargar. Un atacante podría explotar esta vulnerabilidad autenticándose en el dispositivo y cargando una librería maliciosa que puede escalar el nivel de privilegios. Un exploit exitoso podría permitir que el atacante obtenga privilegios de nivel root y obtenga el control total del dispositivo. El atacante debe tener credenciales de usuario válidas para poder iniciar sesión en el dispositivo. Cisco Bug IDs: CSCvc96087. Versiones afectadas conocidas: 1.1(0.920a), 1.1(1j), 1.1(3f); 1.2 Base, 1.2(2), 1.2(3), 1.2.2; 1.3(1), 1.3(2), 1.3(2f); 2.0 Base, 2.0(1).
