CVE-2024-7346

Summary

Host name validation for TLS certificates is bypassed when the installed OpenEdge default certificates are used to perform the TLS handshake for a networked connection.  This has been corrected so that default certificates are no longer capable of overriding host name validation and will need to be replaced where full TLS certificate validation is needed for network security.  The existing certificates should be replaced with CA-signed certificates from a recognized certificate authority that contain the necessary information to support host name validation.

Affected Software

Weaknesses

• CWE-297: CWE-297: Improper Validation of Certificate with Host Mismatch

Workarounds

Replace all use of default OpenEdge TLS certificates with a CA-signed certificate from a recognized certificate authority that contains the necessary information to support host name validation Use the "nohostverify" switch in development environments when clients need to bypass host name validation as a convenience prior to establishing valid certificates for production.
