⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of user sessions, credential theft, redirection to malicious sites, and potential lateral movement within the network.
Likely Case
Session hijacking, information disclosure from authenticated users, and limited impact due to the reflected nature requiring user interaction.
If Mitigated
Minimal impact with proper input validation, output encoding, and security controls in place.
🎯 Exploit Status
Reflected XSS typically requires user interaction (clicking malicious link) but is straightforward to exploit once the vulnerable parameter is identified.

🔍 How to Verify
Check if Vulnerable:
Check iView version in web interface or system properties. If version is below 5.7.05 build 7057, system is vulnerable.Check Version:
Check web interface login page or system information panel for version detailsVerify Fix Applied:
Verify version shows 5.7.05 build 7057 or higher. Test previously vulnerable parameters with XSS payloads to confirm they are now sanitized.📡 Detection & Monitoring
