Overview
A critical vulnerability, designated as CVE-2025-10171, has been identified in UTT 1250GW versions up to 3.2.2-200710. This vulnerability, which resides in the function sub_453DC of the file /goform/formConfigApConfTemp, can lead to a buffer overflow when manipulated. The seriousness of this vulnerability cannot be overstated, given that it allows for remote exploitation and potentially compromises the entire system or leads to data leakage.
This issue poses a significant threat to organizations utilizing UTT 1250GW, as the exploit is now public and may be used by malicious actors. Despite being alerted to this vulnerability, the vendor has failed to respond, exacerbating the potential risks associated with this flaw.

How the Exploit Works
The vulnerability lies within the function sub_453DC of the file /goform/formConfigApConfTemp. When manipulated, it results in a buffer overflow. This overflow can allow malicious actors to execute arbitrary code on the target system, leading to serious consequences such as system compromise or data leakage. The vulnerability can be exploited remotely, which makes it even more dangerous.
Conceptual Example Code
This conceptual example demonstrates how a malicious actor might exploit this vulnerability. Note that this is intended for educational purposes only:
POST /goform/formConfigApConfTemp HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"buffer_overflow_trigger": "Extremely long string or binary data that exceeds buffer size..."
}In this example, the malicious actor sends a POST request with a payload that exceeds the predetermined buffer size. This results in a buffer overflow, which in turn can lead to arbitrary code execution and potential system compromise or data leakage.
Mitigation Guidance
Users are advised to apply a vendor patch as soon as it becomes available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can offer temporary mitigation against this vulnerability. Regular monitoring and timely incident response can also help to limit the damage in case of an exploit.
