CVE-2025-29557Network attack vector

Authenticated SMTP credential disclosure via MailConfiguration API

Published Jul 31, 2025 · Updated Jul 31, 2025

Improper access control in ExaGrid EX10 6.3 through 7.0.1.P08 allows remote authenticated users to read plaintext SMTP credentials. The MailConfiguration API accepts an operator-level HTTP GET request and returns its full SMTP configuration JSON, including usernames and passwords, without enforcing the intended privilege boundary. Operator-level access to the appliance management interface is required; exposure is limited to configured SMTP secrets, with no reported service interruption.
