CVE-2024-4187Network attack vector

External-link warning bypass via stored XSS

Published Jul 31, 2024 · Updated Aug 12, 2024

Stored XSS in OpenText Filr 24.1.1 and 24.2 allows remote authenticated users to suppress warnings when users click external links. OpenText has not disclosed the affected input, storage locus, or output context that renders the persistent script. An authenticated user must store content and another user must interact with the rendered link; the documented consequence is loss of the external-site warning.
