CVE-2023-31059Known exploitationPublic exploitNetwork attack vector

Credential disclosure via encoded backslash path traversal

Published Apr 24, 2023 · Updated Feb 4, 2025

Path traversal in Repetier Server 1.4.10 and earlier allows remote attackers to read arbitrary files through crafted HTTP requests. The request path ending in connectionLost.php accepts URL-encoded backslash traversal segments and resolves them outside the intended views directory. No authentication is required, and exposed files include the user.sql database containing password hashes, API keys, and usernames.
