Broken Authentication Vulnerability.
Broken Authentication vulnerability occurs when "StartTLSEnabled" property is set to "true" in the LDAP user store configuration.
This vulnerability allows anyone to login if a valid username is known. However, "StartTLSEnabled" is not set to "true" by default. Therefore, a deployment is not impacted unless that configuration is turned on explicitly.
If the latest version of the affected WSO2 product is not mentioned under the affected product list, you may migrate to the latest version to receive security fixes. Otherwise you may apply the relevant fixes to the product based on the public fix: https://github.com/wso2/carbon-kernel/pull/2835
