[Vulnerability Type]
Insecure Transit Password Disclosure


[CVE Reference]
CVE-2020-7030
ASA-2020-077


[Security Issue]
A sensitive information disclosure vulnerability exists in the web interface component of IP Office that
may potentially allow a local user to gain unauthorized access to the component.

The request URL on port 7071 and the web socket component requests on port 7070 used by Atmosphere-Framework
within Avaya IP Office, pass Base64 encoded credentials as part of the URL query string.

https://<TARGET-IP>:7071/serveredition/autologin?auth=QWRtaW5pc3RyYXRvcjpBZG1pbmlzdHJhdG9y&referrer=https://x.x.x.x:7070&lang=en_US

wss://<TARGET-IP>:7070/WebManagement/webmanagement/atmosphere/QWRtaW5pc3RyYXRvcjpBZG1pbmlzdHJhdG9y?X-Atmosphere-tracking-id=0&
X-Atmosphere-Framework=2.0.5-javascript&X-Atmosphere-Transport=websocket&X-Cache-Date=0&Content-Type=text/x-gwt-rpc;%20charset=UTF-8&X-atmo-protocol=true

Base64 credentials: QWRtaW5pc3RyYXRvcjpBZG1pbmlzdHJhdG9y
Value: Administrator:Administrator

The Base64 encoded credentials can be easily disclosed if the machine used to logon to the web Manager is accessed by an attacker.
The URL plus the credentials can potentially be leaked or stored in some of the following locations.
