Overview
The cybersecurity landscape is a battleground where developers and malicious attackers continually up their game. In this post, we will focus on a recent vulnerability discovered in Netcad Software Inc.’s Netigma software, CVE-2025-9798, a high-risk Cross-Site Scripting (XSS) vulnerability. This exploit has the potential to compromise entire systems and leak confidential data, posing a significant threat to businesses using affected versions of Netigma. Understanding the details of this vulnerability, its potential impacts, and how to mitigate it, is crucial for businesses to protect their digital assets.

How the Exploit Works
The CVE-2025-9798 vulnerability arises from the improper neutralization of user input during web page generation. This allows an attacker to inject malicious scripts, which are then stored on the server (Stored XSS). When other users access affected pages, the server includes these scripts in the output HTML. The users’ browsers, trusting the server’s output, execute these scripts, which can steal user data, perform actions on their behalf, or even compromise the entire system.
Conceptual Example Code
Below is a conceptual example of how this vulnerability might be exploited using a HTTP request:
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "user_comment": "<script>/*malicious_code_here*/</script>" }In the above example, a malicious script is injected into the ‘user_comment’ parameter. If the server doesn’t correctly sanitize this input, the script will be stored on the server and later served to other users, causing the XSS vulnerability.
Mitigation Guidance
Organizations using vulnerable versions of Netigma are advised to apply the vendor-supplied patch immediately, upgrading to version 6.3.5 V8 or higher. Until the patch can be applied, Web Application Firewalls (WAFs) or Intrusion Detection Systems (IDS) can be used for temporary mitigation. These tools can help detect and prevent known XSS attack patterns, reducing the risk of exploitation. However, they are not a complete solution and should only be used as a temporary measure until the patch can be applied.
