Overview
A serious vulnerability, CVE-2025-28235, has been discovered in Soundcraft Ui Series Firmware which allows unauthenticated attackers to access administrator credentials in plaintext. This vulnerability threatens the security of two models, Ui12 and Ui16, potentially compromising the system or leaking sensitive data. As such, it is of high importance for users of these models to be aware of this vulnerability and take the necessary steps to mitigate it.

Product | Affected Versions
Soundcraft Ui12 | Firmware v1.0.7x, v1.0.5x
Soundcraft Ui16 | Firmware v1.0.7x, v1.0.5x
How the Exploit Works
The exploit works by sending a specific request to the /socket.io/1/websocket/ component of the affected firmware versions. This request triggers the vulnerability, causing the firmware to disclose administrator credentials in plaintext. An attacker does not need any privileges or user interaction to exploit this vulnerability, making it a critical security risk.
Conceptual Example Code
Here is a conceptual example of an HTTP request that might exploit this vulnerability:
GET /socket.io/1/websocket/ HTTP/1.1
Host: target.example.com
Upon receiving this request, the vulnerable system may respond with the administrator credentials in plaintext.
Mitigation
Users of Soundcraft Ui12 and Ui16, with affected firmware versions, should apply the vendor-provided patch to mitigate this vulnerability. In the absence of such a patch, or until it can be applied, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary mitigation. Regularly updating and patching systems, along with continuous monitoring of network traffic, can help in reducing the risk associated with this vulnerability.
