Aviatrix Controller Unrestricted Upload of File (CVE-2021-40870)

critical Nessus Plugin ID 271965

Language:

Synopsis

An issue was discovered in Aviatrix Controller.

Description

While the Aviatrix UI requires authentication, many API calls do not enforce a check for authentication. Some of these API calls allow an unauthenticated attacker to upload arbitrary files, including .php scripts, to the filesystem. These uploaded scripts will be processed by the web frontend, allowing an attacker to run code of their choosing.

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

Solution

Upgrade viatrix Controller to version 6.2-1804.2043, 6.3-1804.2490, 6.4-1804.2838 or 6.5-1804.1922 or later
