Dell EMC Unity Operating Environment versions prior to 5.0.0.0.5.116, Dell EMC UnityVSA versions prior to 5.0.0.0.5.116 and Dell EMC VNXe320
Dell EMC Unity Operating Environment versions prior to 5.0.0.0.5.116, Dell EMC UnityVSA versions prior to 5.0.0.0.5.116 and Dell EMC VNXe3200 versions prior to 3.1.10.9946299 contain a reflected cross-site scripting vulnerability on the cas/logout page. A remote unauthenticated attacker could potentially exploit this vulnerability by tricking a victim application user to supply malicious HTML or Java Script code to Unisphere, which is then reflected back to the victim and executed by the web browser.

Remediation
Which version to upgrade to
Fix versions compiled from the vendor, package registries and Microsoft. Verify the vendor's note before upgrading.
No fix version is recorded for this entry. Check the references for vendor advisories.
Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).
Patch and commit links
Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
