SMTP credential disclosure via cleartext settings page

Published Nov 4, 2024 · Updated Jul 5, 2026

Credential exposure in SMTP settings in 1C-Bitrix Bitrix24 23.300.100 allows remote authenticated users to read SMTP passwords. The SMTP edit page returns the saved password in clear text within its HTML, allowing browser developer tools to expose the password field. Administrator privileges and a configured SMTP account are required, and the consequence is disclosure of that account credential.
