CVE-2024-2391Public exploitNetwork attack vector

Stored XSS via unsanitized lab text labels

Published Mar 12, 2024 · Updated Aug 1, 2024

Stored cross-site scripting in the Lab Handler of EVE-NG 5.0.1-13 allows remote authenticated users to run script in another user's browser. The lab text-label editor stores unsanitized markup, and the Lab Handler renders the saved label so its script executes when another user opens the lab. An account able to create a lab and save a text label can alter page content in a viewing user's session; the public test covers Community Edition only.
