MEDIUM 4.8EPSS 0.62%

Does this matter?

Lower severity and a low EPSS score (0.62%). Track it; it rarely justifies an emergency change on its own.

Description

Dell EMC ECS versions prior to 3.4.0.1 contain an XSS vulnerability. A remote authenticated malicious user could exploit this vulnerability to store malicious HTML or JavaScript code in a trusted application data store. When victim users access the data store through their browsers, the malicious code gets executed by the web browser in the context of the vulnerable web application.
