Those FileIDs may later be used for unauthorized access the corresponding file using vulnerability CVE-2015-7675 (https://profundis-labs.com/advisories/CVE-2015-7675.txt). To exploit this vulnerability, the following information is needed: - A valid user account (user session) PoC code(s): ============ POST /MOVEitISAPI/MOVEitISAPI.dll?action=download HTTP/1.1 Host: <DNSNAME> ... X-siLock-FileID: <FileID> The response from server can be evaluated as followed: - FileID exists but user is not permitted, error message: "Sie sind nicht zum Lesen dieser Datei berechtigt" (Error message is in German, it may differ in setups with other languages) - FileID does not exist, error message: No such file ID "<FileID>" (this error message is always in English) Remark: Values in Brakets are placeholders.
