Summary
Dell PowerProtect Data Domain with DD OS contains a cross-site scripting vulnerability. A high-privileged attacker with remote access could exploit it to inject scripts.
Risk Assessment
Potential execution of malicious script in a user's browser context, session or data theft, and follow-on attacks. Exploitation requires high attacker privileges.
Recommendation
Update DD OS to the Dell-recommended fixed release. Restrict administrative access to the interface and enforce security headers (CSP) and input validation.
