Browser script execution via active SWF upload

Published Mar 30, 2020 · Updated Aug 5, 2024

Stored XSS in Intland codeBeamer ALM 9.5 and earlier allows remote authenticated users to run scripts through uploaded SWF files. The Upload Flash File attachment path accepts a crafted SWF containing active script and later serves that active content without neutralizing it. Exploitation requires an authenticated uploader and a separate user to open the stored file, causing script execution in that user's browser context.
