Stored XSS via permissive hosting-plan validation
Published Oct 13, 2023 · Updated Sep 17, 2024
Stored XSS in Froxlor before 2.0.22 allows remote authenticated users to execute scripts in another user's browser via hosting-plan fields. HostingPlans.add and HostingPlans.update apply permissive validation to plan names and descriptions, allowing stored markup to reach rendered pages. Administrator access is required to write the fields, and exploitation requires another user to view the stored plan data; the script can read or alter data available to that browser session.
