A recently discovered vulnerability in the Avaya Scopia Pathfinder 10 and 20 PTS version 8.3.7..4, identified as CVE-2022-38168, could allow unauthenticated remote attackers to bypass login pages, access sensitive information, and reset user passwords. This blog post will delve into the details of the vulnerability, explaining its cause, how it could be exploited, and potential repercussions for affected organizations. Further, we will discuss mitigation measures that can be implemented to protect your systems from this type of attack.

Vulnerability Overview

Avaya Scopia Pathfinder is a Session Initiation Protocol (SIP) traversal solution used in video conferencing systems. The mentioned vulnerability, CVE-2022-38168, arises due to broken access control in user authentication.

Exploit Details

A remote attacker can exploit this flaw by modifying the URL of the affected system, which would allow them to bypass the login page, access sensitive information, and even reset user passwords. For instance, an attacker could manipulate the URL as shown below:


This would enable them to reset the admin user's password easily, allowing unauthorized access to the system's sensitive information and administrative privileges.

The exploitation of this vulnerability could lead to

1. Unauthorized access to sensitive information: Attackers could access critical data, such as user details, saved materials, and other sensitive assets.

2. Privilege escalation: By resetting user passwords, particularly those of administrator accounts, attackers could seize control of the affected systems, giving them the power to perform various malicious activities.

3. Loss of availability: The vulnerability could be exploited to carry out denial-of-service (DoS) attacks, causing affected systems to become unavailable for intended use.

4. Reputational damage: Organizations that fall victim to such attacks may suffer a loss of trust from their clients and partners, in addition to the financial and legal ramifications.

The following sources have discussed this vulnerability in detail

1. CVE-Record: Original CVE details from the MITRE Corporation.
