Synopsis

The remote device is missing a vendor-supplied security patch

Description

The version of Cisco SD-WAN vManage Software installed on the remote host is affected by multiple vulnerabilities as referenced in the cisco-sa-vmanage-YuTVWqy advisory, as follows:

- A vulnerability in the remote management component allows an unauthenticated, remote attacker to cause a buffer overflow and execute arbitrary code on the underlying operating system with root privileges. This is due to improper validation of user-supplied input. An attacker can exploit this by sending a crafted connection request. (CVE-2021-1479)

- A vulnerability in the user management function allows an authenticated, local attacker to gain root privileges on the underlying operating system due to insufficient input validation. An attacker can exploit this by modifying a user account. (CVE-2021-1137)

- A vulnerability in the system file transfer functions allows an authenticated, local attacker to gain root privileges on the underlying operating system due to improper validation of input to the system file transfer functions. An attacker can exploit this by sending crafted requests. (CVE-2021-1480)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
