CVE-2020-26074
Descripción es
Una vulnerabilidad en las funciones de transferencia de archivos del sistema de Cisco SD-WAN vManage Software podría permitir que un atacante local autenticado obtenga privilegios elevados en el sistema operativo subyacente. La vulnerabilidad se debe a una validación incorrecta de la entrada de ruta a las funciones de transferencia de archivos del sistema. Un atacante podría aprovechar esta vulnerabilidad enviando solicitudes que contengan variables de ruta especialmente diseñadas al sistema vulnerable. Una explotación exitosa podría permitir al atacante sobrescribir archivos arbitrarios, lo que le permitiría modificar el sistema de tal manera que podría permitirle obtener privilegios elevados. Cisco ha publicado actualizaciones de software que solucionan esta vulnerabilidad. No existen workarounds que solucionen esta vulnerabilidad.
Descripción en
A vulnerability in system file transfer functions of Cisco SD-WAN vManage Software could allow an authenticated, local attacker to gain escalated privileges on the underlying operating system.
The vulnerability is due to improper validation of path input to the system file transfer functions. An attacker could exploit this vulnerability by sending requests that contain specially crafted path variables to the vulnerable system. A successful exploit could allow the attacker to overwrite arbitrary files, allowing the attacker to modify the system in such a way that could allow the attacker to gain escalated privileges.Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
