📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, gain full control of the InfoSphere environment, and potentially access sensitive data or pivot to other systems.
Likely Case
Attackers could steal user session cookies or credentials, leading to unauthorized access to the InfoSphere platform and potential data exposure.
If Mitigated
With proper input validation and output encoding, the risk is reduced to minimal, though the vulnerability still exists in the codebase.
🎯 Exploit Status
XSS vulnerabilities are commonly exploited and require authenticated access to the web interface.
