📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers steal administrator credentials, gain full control of the B2B integration system, and potentially compromise connected business partner systems and data.
Likely Case
Attackers steal session cookies or credentials from authenticated users, enabling unauthorized access to the B2B integration platform.
If Mitigated
With proper input validation and output encoding, malicious scripts are neutralized before execution, preventing credential theft.
🎯 Exploit Status
XSS vulnerabilities typically have low exploitation complexity. No authentication is required to trigger the vulnerability.
