CVE-2020-2300
Improper Authentication (empty password) in Jenkins Active Directory Plugin
Description
Jenkins Active Directory Plugin implements two separate modes: Integration with ADSI on Windows, and an OS agnostic LDAP-based mode. The Windows/ADSI mode does not specifically prohibit use of empty passwords in Active Directory Plugin prior to 2.20 and 2.16.1. If the Active Directory server allows the unauthenticated bind operation, this allows attackers to log in to Jenkins as any user by providing an empty password. Jenkins Active Directory Plugin 2.20 and 2.16.1 prohibits the use of an empty password to log in.
