CVE-2014-X80X

The Code Review Patch challenges are designed to enhance your skills in identifying and understanding vulnerabilities within code. Each challenge provides you with the unpatched, vulnerable code as well as the corresponding patch. Your task is to first attempt to find the security issue on your own, without looking at the patch. This approach helps in developing a keen eye for spotting potential vulnerabilities.

If you struggle to identify the issue or want to verify your findings, you can then refer to the patch (the diff file) for guidance. In this specific lab, the code concerns an LDAP authenticator in the Apache CloudStack project. The patch introduces checks to ensure that neither the username nor the password is empty before proceeding with authentication. These checks are crucial in fortifying the authentication process against common vulnerabilities.
