CVE-2024-45176
📋 TL;DR
CVE-2024-45176 is a reflected cross-site scripting (XSS) vulnerability in za-internet C-MOR Video Surveillance 5.2401 web interface. Attackers can inject malicious scripts via insufficiently validated user inputs, which execute in victims' browsers when they visit crafted URLs. Organizations using C-MOR Video Surveillance 5.2401 are affected.
💻 Affected Systems
- za-internet C-MOR Video Surveillance
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator session cookies, hijack administrative accounts, deploy malware to surveillance systems, or pivot to internal networks.
Likely Case
Attackers craft phishing emails with malicious links to steal session cookies from authenticated users, leading to unauthorized access to the surveillance system.
If Mitigated
With proper input validation and output encoding, malicious scripts are neutralized before execution, preventing exploitation.
🎯 Exploit Status
Exploitation requires user interaction (clicking a malicious link), but no authentication is needed to trigger the XSS payload.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched version
Vendor Advisory: https://www.syss.de/fileadmin/dokumente/Publikationen/Advisories/SYSS-2024-020.txt
Restart Required: Yes
Instructions:
1. Review vendor advisory for patch details. 2. Backup system configuration. 3. Apply the official patch from za-internet. 4. Restart C-MOR services. 5. Verify fix by testing vulnerable endpoints.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with XSS protection rules to filter malicious inputs before they reach the application.
Input Validation at Proxy
linuxConfigure reverse proxy or load balancer to sanitize user inputs targeting C-MOR endpoints.
🧯 If You Can't Patch
- Implement strict Content Security Policy (CSP) headers to restrict script execution sources.
- Disable or restrict access to the web interface from untrusted networks.
🔍 How to Verify
Check if Vulnerable:
Test web interface endpoints with XSS payloads (e.g., <script>alert('XSS')</script>) in URL parameters; if script executes, system is vulnerable.Check Version:
Check C-MOR web interface login page or admin panel for version information, typically displayed in footer or about section.Verify Fix Applied:
Retest with same XSS payloads after patching; scripts should be encoded or blocked, not executed.📡 Detection & Monitoring
Log Indicators:
- Unusual long strings or script tags in web server access logs for C-MOR URLs
- Multiple failed login attempts followed by suspicious parameter values
Network Indicators:
- HTTP requests with encoded script tags or JavaScript in query parameters to C-MOR endpoints
- Traffic spikes from single IPs with crafted URLs
SIEM Query:
source="web_logs" AND url="*c-mor*" AND (url="*<script>*" OR url="*javascript:*")
