Vulnerability in Apache Nifi Minifi C\+\+

CVE-2023-41180

Incorrect certificate validation in InvokeHTTP on Apache NiFi MiNiFi C++ versions 0.13 to 0.14 allows an intermediary to present a forged certificate during TLS handshake negotation. The Disable Peer Verification property of InvokeHTTP was effectively flipped, disabling verification by default, when using HTTPS. Mitigation: Set the Disable Peer Verification property of InvokeHTTP to true when using MiNiFi C++ versions 0.13.0 or 0.14.0. Upgrading to MiNiFi C++ 0.15.0 corrects the default behavior.
