Overview
CVE-2025-10953 is a critical security vulnerability that was recently discovered in UTT 1200GW and 1250GW routers. This particular flaw exposes these routers, running versions up to 3.0.0-170831/3.2.2-200710, to potential remote attacks that could compromise the system or lead to data leakage. This vulnerability matters because UTT routers are widely used across various sectors, including businesses and homes, potentially putting countless systems and data at risk.

How the Exploit Works
The vulnerability resides in the /goform/formApMail file of the affected routers. A remote attacker can exploit this by manipulating the senderEmail argument, leading to a buffer overflow. Buffer overflow vulnerabilities occur when more data is put into a buffer than it can handle. This overflow can overwrite adjacent memory locations, potentially leading to arbitrary code execution, system crashes, or information leaks.
Conceptual Example Code
Here is a conceptual example of how an HTTP request exploiting this vulnerability might look:
POST /goform/formApMail HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
senderEmail=AAAAAA... # Long string causing buffer overflowIn this example, the attacker sends an HTTP POST request with an overly long string as the senderEmail. This string is larger than the buffer allocated for it, causing an overflow.
Mitigation and Remediation
Despite this vulnerability’s severity and the vendor’s lack of response, there are still steps that can be taken to mitigate this risk. If a patch from the vendor becomes available, it should be applied immediately. Until then, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These systems can detect and block malicious traffic, potentially preventing exploitation of this vulnerability. Additionally, consider limiting access to the router’s management interface to trusted networks only and regularly updating all devices connected to the network.
