CVE-2023-5257Public exploit

File disclosure via unchecked HTTP request paths

Published Sep 29, 2023 · Updated Aug 2, 2024

Path traversal in WhiteHSBG JNDIExploit 1.4 on Windows allows attackers to read files outside the HTTP service's data directory. The handleFileRequest function resolves attacker-controlled request paths without confining the result to the intended serving directory. The HTTP service must be reachable from an adjacent network; successful traversal discloses readable host files without altering them.
