The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity
Low
AC
The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required
None
PR
The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction
None
UI
The vulnerable system can be exploited without interaction from any human user, other than the attacker. Examples include: a remote attacker is able to send packets to a target system a locally authenticated attacker executes code to elevate privileges
Scope
Unchanged
S
An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality
High
C
There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity
High
I
There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file on the target system.
Availability
High
A
There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.

Avaya IP Office v9.1.8.0 - 11
IP Office Platform provides a single, stackable, scalable small business communications system that grows with your business easily and cost-effectively.
[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.
