CVE-2024-34883Public exploitNetwork attack vector

Administrator credential disclosure via plaintext DAV setting

Published Nov 4, 2024 · Updated Jul 5, 2026

Credential exposure in DAV settings in Bitrix24 23.300.100 allows remote authenticated users with administrator access to read proxy passwords. The DAV module's Proxy settings page places the proxy_password value in page source returned by an HTTP GET request instead of withholding the stored secret. Administrator access and a configured proxy account are required, and the demonstrated consequence is disclosure of that account's password.
