Mule Misconfiguration: Server Identity Verification Disabled

Universal

Abstract

The Mule configuration specifies a TLS connection without the server certificate validation check.

Explanation

Certification verification is essential to confirm the counterpart's identity for secure communication. A tls:context element defines a set of TLS connection configurations. Among the configurations, the tls:trust-store element specifies a file that contains certificates from trusted Certificate Authorities that a client uses to verify a certificate presented by a server. By default, the Mule runtime engine verifies the server certificate for every TLS connection.

However, if the value of the insecure attribute of the tls:trust-store element is true, server certificates are accepted without verification.

Example 1: The following Mule configuration sets the insecure attribute to true. As a result, the Mule runtime engine does not verify the server certificate of any connection with the TLS context named demoTlsContext. Such a connection is susceptible to a man-in-the-middle attack.


...
<tls:context name="demoTlsContext">
...
    <tls:trust-store ... insecure="true" ... />
...
<tls:context/>
...
