How the CVE Works:
CVE-2025-3326 is a stored Cross-Site Scripting (XSS) vulnerability in iTeaj iBoot IoT Gateway version 1.1.3. The flaw exists in the `/common/upload` file upload component, where improper input sanitization allows an attacker to inject malicious JavaScript via the `File` parameter. When an authenticated user accesses the uploaded file, the script executes in their browser session, enabling session hijacking, phishing, or unauthorized actions. The attack is remotely exploitable with low privileges, requiring only user interaction (UI:P). The CVSS 4.0 score of 5.1 (MEDIUM) reflects its moderate impact due to the need for user interaction and limited scope.
DailyCVE Form:
Platform: iTeaj iBoot IoT Gateway
Version: 1.1.3
Vulnerability: Stored XSS
Severity: Medium
Date: 04/08/2025
What Undercode Say:
Exploitation:
- Craft a malicious file (e.g.,
exploit.html) containing XSS payload:<script>alert(document.cookie);</script>
2. Upload via `/common/upload` with manipulated `File` parameter:
curl -X POST -F "[email protected]" http://<target>/common/upload
3. Trigger execution by luring a user to view the uploaded file.
Mitigation:
1. Patch: Apply vendor updates for input sanitization.
2. WAF Rules: Block suspicious uploads with regex:
location /common/upload {
if ($args ~ "File=.<script") { return 403; }
}
3. CSP Header: Restrict script execution:
Content-Security-Policy: default-src 'self'
Detection:
Scan for vulnerable endpoints:
grep -r "/common/upload" /var/www/
Log Analysis:
Monitor upload logs for XSS patterns:
cat /var/log/nginx/access.log | grep -i "script"
