## Technical details

IBM Netezza Software versions 11.3.0.3 through Interim Fix 002 do not properly validate TLS/SSL certificates during secure communications. The vulnerability allows an attacker with network-level access to perform man-in-the-middle (MITM) attacks by presenting an invalid or spoofed certificate that the application will accept. No authentication or user interaction is required; the flaw is exposed to any attacker with network access between the client and Netezza server. An attacker can intercept encrypted traffic and harvest sensitive information including credentials, configuration data, and query results. The vulnerability has been addressed in IBM Netezza Software version 11.3.1.3 or later.
