How the CVE Works:
CVE-2025-43946 exploits TCPWave DDI 11.34P1C2 by combining an unrestricted file upload vulnerability with path traversal. Attackers can upload malicious files (e.g., webshells) to arbitrary directories due to insufficient validation. The path traversal allows them to overwrite critical system files or place executable scripts in web-accessible locations, leading to remote code execution (RCE) under the context of the web server.
DailyCVE Form:
Platform: TCPWave DDI
Version: 11.34P1C2
Vulnerability: RCE via File Upload
Severity: Critical
Date: 06/23/2025
Prediction: Patch expected by 08/2025
What Undercode Say:
curl -X POST -F "[email protected]" http://target/upload grep -r "upload_dir" /etc/tcpwave/
How Exploit:
1. Craft a malicious payload (e.g., PHP webshell).
- Bypass upload filters using double extensions (e.g.,
shell.php.jpg). - Leverage path traversal to place the file in
/var/www/html.
Protection from this CVE:
1. Disable file uploads if unnecessary.
2. Implement strict file extension checks.
3. Apply vendor patches immediately.
Impact:
Full system compromise, data exfiltration, and lateral movement within the network.
