Odyssey passes to client unencrypted bytes from man-in-the-middle When Odyssey storage is configured to use the PostgreSQL server using trust authentication with a clientcert requirement or to use cert authentication, a man-in-the-middle attacker can inject false responses to the clients first few queries. Despite the use of SSL certificate verification and encryption, Odyssey will pass these results to client as if they originated from valid server. This is similar to CVE-2021-23222 for PostgreSQL.

Weakness

The product does not validate, or incorrectly validates, a certificate.
