Citrix SD-WAN Center and NetScaler SD-WAN Center addModifyZTDProxy Unauthenticated Remote Command Injection

critical Nessus Plugin ID 130347
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote host is affected by a remote command injection vulnerability.

Description

The remote Citrix SD-WAN Center or NetScaler SD-WAN Center is affected by a remote command injection vulnerability due to improper sanitization of user-supplied input in the addModifyZTDProxy action of NmsController. An unauthenticated, remote attacker can exploit this, via a specially crafted HTTP request, to execute arbitrary commands on the remote host with root privileges.

Note that Nessus can perform an additional check for this vulnerability. To do so, re-run the scan with the setting 'Perform thorough tests (may disrupt your network or impact scan speed)' enabled.

Solution

Upgrade to Citrix SD-WAN Center version 10.2.3 or later or NetScaler SD-WAN Center version 10.0.8 or later.
