CVE-2023-50179Network attack vector

SDN traffic interception via missing certificate validation

Published Jul 9, 2024 · Updated Aug 2, 2024

Improper certificate validation in Fortinet FortiADC 7.0 through 7.4.0 allows remote attackers to intercept public SDN connector traffic. The connector's TLS client does not validate the peer certificate when establishing secure connections with public SDN services, enabling endpoint impersonation. Exploitation requires a network position between an enabled connector and its service and permits disclosure or alteration of data exchanged over that channel.
