Doc Text:
A flaw was found in Ceph. An attacker can allow Ceph to accept any certificate because no certificate context is passed via Pybind to the constructors imaplib.IMAP4_SSL or smtplib.SMTP_SSL. As a result, pybind pybind does not check the server's X.509 certificate, instead accepting any certificate. This enables an attacker to commit a Man In the Middle (MITM) attack, compromising mail server credentials or mail contents

Description OSIDB Bzimport 2025-08-20 20:51:12 UTC
Ceph uses Pybind in a way which does not implement proper certificate checking. This impacts confidentiality and integrity, as an attacker may exploit an unset SSL context to allow the use of any certificate.
