A vulnerability was found in OpenShift builds, versions 4.1 up to 4.3. Builds that extract source from a container image, bypass the TLS hostname verification. An attacker can take advantage of this flaw by launching a man-in-the-middle attack and injecting malicious content.

This example loads an external class from a local subdirectory.
Class loadedClass = Class.forName("loadMe", true, loader);new URL("file:subdir/")This code does not ensure that the class loaded is the intended one, for example by verifying the class's checksum. An attacker may be able to modify the class file to execute malicious code.
This code includes an external script to get database credentials, then authenticates a user against the database, allowing access to the application.
}//assume the password is already encrypted, avoiding CWE-312}//dbInfo.php makes $dbhost, $dbuser, $dbpass, $dbname availablereturn true;return false;This code does not verify that the external domain accessed is the intended one. An attacker may somehow cause the external domain name to resolve to an attack server, which would provide the information for a false database. The attacker may then steal the usernames and encrypted passwords from real user login attempts, or simply allow himself to access the application without a real user account.
This example is also vulnerable to a MITM (CWE-300) attack.
