CVE-2022-38794Public exploitNetwork attack vector

Sensitive file disclosure via directory traversal

Published Aug 27, 2022 · Updated Aug 3, 2024

Zaver through 2020-12-15 allows remote attackers to read sensitive files through crafted GET requests containing directory traversal sequences. The request path accepts a GET /.. substring and fails to confine file resolution to the intended directory, exposing files such as configuration and shell files. The endpoint is remotely reachable without authentication, and the demonstrated consequence is confidentiality loss without evidence of file modification or service interruption.
