📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers steal administrator credentials, gain full control of the Poly Clariti Manager, and compromise all managed communication devices, potentially eavesdropping on sensitive communications.
Likely Case
Attackers steal session cookies to hijack administrator sessions, modify device configurations, or deploy malware to users accessing the compromised interface.
If Mitigated
With proper input validation and output encoding, malicious scripts are neutralized, preventing execution while maintaining legitimate functionality.
🎯 Exploit Status
Reflected XSS typically requires social engineering to trick users into clicking malicious links. No authentication required to trigger vulnerability.

🔍 How to Verify
Check if Vulnerable:
Test with harmless payload like <script>alert('test')</script> in URL parameters and observe if script executesCheck Version:
Login to Poly Clariti Manager web interface and check version in System Information/About sectionVerify Fix Applied:
After patching, test same XSS payloads - they should be properly encoded/sanitized in response📡 Detection & Monitoring
Log Indicators:
- Unusual long parameter values in web logs
- Requests containing script tags or JavaScript in URL parameters
- Multiple failed XSS attempts from same source
Network Indicators:
- HTTP requests with encoded script payloads in query strings
- Traffic patterns showing users being redirected to malicious sites
SIEM Query:
source="web_logs" AND (url="*<script>*" OR url="*javascript:*" OR url="*onload=*" OR parameter="*alert(*")
