CVE-2021-29011Public exploitNetwork attack vector

Session-cookie theft via stored administrative-field scripts

Published Apr 2, 2021 · Updated Aug 3, 2024

Stored XSS in DMA Softlab Radius Manager 4.4.0 allows remote authenticated users to execute scripts in a privileged user's browser. The admin.php create and edit handlers store unneutralized script markup from manager, user, access-point, NAS, and service-plan fields and render it later. An account with sufficient create or edit privileges is required; a privileged viewer who opens the record can have a session cookie stolen.
