In today’s highly competitive market, communication plays a crucial role in the success of businesses. Video conferencing systems such as Polycom RealPresence Group 500 enable seamless collaboration and interaction among teams. However, as with any technological solution, these systems need to be adequately secured to safeguard sensitive data.

A recent analysis reveals a potential security vulnerability (CVE-2025-22918) affecting the Polycom RealPresence Group 500 series firmware version 20 and below. This post will provide a detailed examination of this vulnerability, its exploitation, mitigations, and relevant references.

Vulnerability Details

CVE-2025-22918 is a vulnerability in the Polycom RealPresence Group 500 series due to Insecure Permissions as a result of automatically loaded cookies. This issue enables attackers to access and use administrator functions without proper authorization, potentially leading to the leakage of sensitive user information.

Exploit

To exploit this vulnerability, an attacker needs to intercept the traffic between the user and the Polycom RealPresence Group 500 system. This can be done using a packet sniffer such as Wireshark to capture the HTTP traffic.

Upon intercepting the HTTP request, the attacker will notice that a cookie is automatically loaded with the request, granting them access to administrative functions without proper authentication. Below is a sample code snippet showcasing the intercepted HTTP request:

GET /admin/index.html HTTP/1.1
Host: [Target IP]
User-Agent: Mozilla/5. (Windows NT 10.; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58..3029.110 Safari/537.36 Edge/16.16299
Accept: text/html,application/xhtml+xml,application/xml;q=.9,image/webp,image/apng,*/*;q=.8
Accept-Language: en-US,en;q=.9
Cookie: cookie_key=value
Connection: keep-alive

To demonstrate the exploit, the attacker can use a tool such as Burp Suite to modify the captured HTTP request and access the admin panel without proper credentials. Once in the admin panel, sensitive user information can be accessed, potentially leading to data leakage or further exploitation of the system.

Use a strong and unique alphanumeric password for administrator accounts.

3. Enforce HTTPS connections for secure communication between the user and the Polycom RealPresence Group 500 system.

4. Segregate network access by placing IoT devices, including video conferencing systems, on a separate subnet, restricting unauthorized access.
