Cisco SD-WAN Software Arbitrary File Corruption (cisco-sa-sdwan-arbfile-7Qhd9mCn)

medium Nessus Plugin ID 149364

Language:

Synopsis

The remote device is missing a vendor-supplied security patch

Description

According to its self-reported version, Cisco SD-WAN Viptela Software is affected by an arbitrary file corruption vulnerability. A vulnerability in the CLI of Cisco SD-WAN Software could allow an authenticated, local attacker to overwrite arbitrary files in the underlying file system of an affected system. This vulnerability is due to insufficient validation of the user-supplied input parameters of a specific CLI command. An attacker could exploit this vulnerability by issuing that command with specific parameters. A successful exploit could allow the attacker to overwrite the content in any arbitrary files that reside on the underlying host file system.

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

Solution

Upgrade to the relevant fixed version referenced in Cisco bug ID CSCvs98457
