Unauthenticated file disclosure via tampered download path
Published Jan 27, 2022 · Updated Aug 3, 2024
Authorization bypass in Synametrics SynaMan before 5.0 allows remote attackers to read unshared files through a crafted download URL. The file-download URL accepts the base64-encoded fn parameter as a file path and returns the named file without checking that it was shared. No account is required, but an existing public link and a guessed filename are needed; successful exploitation discloses files in the link owner's home folder.
