Unauthenticated file disclosure via link path traversal
Published Aug 31, 2021 · Updated May 5, 2025
Path traversal in Digital Zoom Studio ZoomSounds 6.45 and earlier allows remote attackers to download arbitrary server files. The unauthenticated dzsap_download action treats the link parameter as a file path without constraining traversal outside the intended directory. No account or user interaction is required, and exposed files can include WordPress database credentials and authentication keys in wp-config.php.
