Nextcloud Server before 9.0.52 & ownCloud Server before 9.0.4 are
vulnerable to a log pollution vulnerability potentially leading to a local
XSS. The download log functionality in the admin screen is delivering the
log in JSON format to the end-user. The file was delivered with an
attachment disposition forcing the browser to download the document.
However, Firefox running on Microsoft Windows would offer the user to open
the data in the browser as an HTML document. Thus any injected data in the
log would be executed.
