Overview
The world of cybersecurity is often a game of cat and mouse, with vulnerabilities emerging and patches being released in response. One such vulnerability, identified as CVE-2025-44886, has been discovered in the software FW-WGS-804HPT v1.305b241111. This vulnerability, if exploited, could potentially lead to a system compromise or significant data leakage. The issue lies within a stack overflow vulnerability that can be triggered via the byruleEditName parameter in the web_acl_mgmt_Rules_Edit_postcontains function.
This vulnerability poses a tremendous risk to organizations utilizing the affected software, as unauthorized actors could potentially gain control of critical systems or gain access to sensitive data. It is imperative for organizations to understand this vulnerability, assess their potential exposure, and take necessary mitigation steps.

How the Exploit Works
An attacker exploiting the CVE-2025-44886 vulnerability can send a specifically crafted request containing an excessively long string to the byruleEditName parameter in the web_acl_mgmt_Rules_Edit_postcontains function. This can cause a stack overflow, allowing the attacker to execute arbitrary code or potentially gain control over the system.
Conceptual Example Code
Here is a conceptual example of how an attacker might exploit this vulnerability. Please note that this is a simplified example for illustrative purposes only:
POST /web_acl_mgmt_Rules_Edit_postcontains HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
byruleEditName=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA...(continuing until the stack overflows)In this example, the ‘A’s represent an excessively long string that when processed by the web_acl_mgmt_Rules_Edit_postcontains function, would trigger a stack overflow, opening the door for further exploitation.
Protection Against This Vulnerability
To mitigate the risks posed by this vulnerability, users of the affected software are strongly encouraged to apply the patch provided by the vendor as soon as possible. If the patch cannot be applied immediately, it is recommended to use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary measure to detect and block exploitation attempts. Regularly updating and patching software is a key part of maintaining a robust cybersecurity posture.
