⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, hijack user sessions, deface the interface, or redirect users to malicious sites, potentially leading to full system compromise.
Likely Case
Attackers inject malicious JavaScript to steal session cookies or credentials from authenticated users, enabling unauthorized access to the Logpoint system.
If Mitigated
With proper web application firewalls and input sanitization, the risk is reduced to minimal impact, though the vulnerability still exists.
🎯 Exploit Status
XSS vulnerabilities typically have low exploitation complexity once the injection points are identified.
