CVE-2024-49782Network attack vector

Notification disclosure via mail server impersonation

Published Feb 20, 2025 · Updated Aug 15, 2025

Improper certificate validation in IBM OpenPages 8.3 and 9.0 allows remote authenticated users to spoof an SSL/TLS mail server. The outbound email notification client accepts a mail server certificate whose identity does not match the configured hostname; IBM has not disclosed the responsible function or validation call. Exploitation requires control of the presented mail-server identity and can expose notification contents or interrupt their delivery.
