What is CVE-2020-5893?

In certain versions of the BIG-IP Edge Client, users connecting to a VPN over an unsecure network may inadvertently expose authentication credentials. The client responds to authentication requests using HTTP rather than HTTPS, creating a significant risk of sensitive data interception. This occurs while the client is attempting to detect captive portals, thereby compromising secure communications.
