Overview
In the ever-evolving landscape of cybersecurity, a new vulnerability has been discovered which has the potential to compromise systems or lead to significant data leakage. This vulnerability, catalogued as CVE-2025-44884, affects the FW-WGS-804HPT system, specifically the version v1.305b241111. As a significant threat, it necessitates immediate attention and mitigation to prevent potential breaches and system compromises.
This vulnerability particularly matters as it offers an exploit via the web_sys_infoContact_post function, which essentially results in a stack overflow. Given the severity of this exploit, it is crucial for system administrators, security professionals, and stakeholders leveraging the FW-WGS-804HPT system, to understand and take prompt action against this vulnerability.

FW-WGS-804HPT | v1.305b241111
How the Exploit Works
The exploit takes advantage of a stack overflow vulnerability in the web_sys_infoContact_post function of the FW-WGS-804HPT system. A stack overflow condition is a type of buffer overflow where a program writes more data to a buffer located on the stack than what is actually allocated for that buffer. This results in the program overwriting adjacent memory locations.
An attacker can manipulate the data sent to this function, causing the system to try and store more data than its allocated memory can handle, leading to a stack overflow. This overflow can result in erratic behavior, crashes, or in some cases, execution of arbitrary or malicious code.
Conceptual Example Code
Here is a
conceptual
example of how an HTTP request exploiting this vulnerability might look:
POST /web_sys_infoContact_post HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"data": "A".repeat(1000000) // A string larger than stack allocation
}In this example, the data field is filled with a string that exceeds the stack allocation, causing a stack overflow and potentially allowing the execution of arbitrary code.
Mitigation Guidance
The mitigation of this vulnerability primarily involves applying a patch provided by the vendor. If the patch is not available or cannot be applied immediately, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as a temporary mitigation measure. These tools can monitor the network for signs of this exploit and block or alert administrators to suspicious activity.
However, these are temporary solutions. The definitive mitigation of this vulnerability would be to update to a version of the software that has addressed this flaw.
