CVE-2021-32598Public exploitNetwork attack vector

HTTP response control via unsanitized filename parameter

Published Aug 5, 2021 · Updated Oct 25, 2024

HTTP response splitting in Fortinet FortiManager and FortiAnalyzer affected releases allows remote authenticated users to alter HTTP responses. The SOMAdomRevisionDiff CGI copies the user-controlled to parameter into a Content-Disposition filename without rejecting CR or LF characters. A valid GUI session is required; crafted GET or POST parameters let the requester control the remaining response headers and body.
