Overview
The Common Vulnerabilities and Exposures (CVE) system has identified a high-severity vulnerability (CVE-2025-53475) in Advantech iView. This vulnerability exposes systems to potential SQL injection attacks and remote code execution. The impact of such vulnerabilities can be significant, potentially leading to system compromise and data leakage. This vulnerability matters due to the potential damage that could occur if an attacker with at least user-level privileges successfully exploits it.

How the Exploit Works
The vulnerability exists in the Advantech iView NetworkServlet.getNextTrapPage() function, which fails to properly sanitize certain parameters. If an attacker can authenticate with at least user-level privileges, they can exploit this vulnerability to perform SQL injection attacks. This could also lead to the execution of arbitrary code in the context of the ‘nt authority\local service’ account, which could potentially compromise the system.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited via malicious HTTP request:
POST /NetworkServlet/getNextTrapPage HTTP/1.1
Host: target.example.com
Content-Type: application/json
Cookie: JSESSIONID=[Authenticated Session ID]
{
"trapPage": "1; DROP TABLE users --"
}In this example, the attacker sends a malicious payload within the “trapPage” parameter. Since the application does not properly sanitize the input, it directly executes the SQL command, potentially leading to data loss or unauthorized data access.
Mitigation
The best mitigation strategy for this vulnerability is to apply the vendor-supplied patch as soon as possible. Until the patch can be applied, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) may help to temporarily mitigate some of the risks associated with this vulnerability. However, these are not long-term solutions and the patch should be applied as soon as it is available.
