CVE-2020-2300jenkins projectjenkins active directory plugin+2
EPSS score1.67%
Jenkins Active Directory Plugin 2.19 and earlier does not prohibit the use of an empty password in Windows/ADSI mode, which allows attackers to log in to Jenkins as any user depending on the configuration of the Active Directory server.CVE-2020-2299jenkins projectjenkins active directory plugin+2EPSS score1.34%
Jenkins Active Directory Plugin 2.19 and earlier allows attackers to log in as any user if a magic constant is used as the password.CVE-2020-2303jenkins projectjenkins active directory plugin+2EPSS score0.68%
A cross-site request forgery (CSRF) vulnerability in Jenkins Active Directory Plugin 2.19 and earlier allows attackers to perform connection tests, connecting to attacker-specified or previously configured Active Directory servers using attacker-specified credentials.CVE-2020-2302jenkins projectjenkins active directory plugin+2EPSS score0.68%
A missing permission check in Jenkins Active Directory Plugin 2.19 and earlier allows attackers with Overall/Read permission to access the domain health check diagnostic page.CVE-2020-2301jenkins projectjenkins active directory plugin+2EPSS score1.70%
Jenkins Active Directory Plugin 2.19 and earlier allows attackers to log in as any user with any password while a successful authentication of that user is still in the optional cache when using Windows/ADSI mode.CVE-2022-23105jenkins projectjenkins active directory plugin+2EPSS score0.45%
Jenkins Active Directory Plugin 2.25 and earlier does not encrypt the transmission of data between the Jenkins controller and Active Directory servers in most configurations.CVE-2017-2649jenkins projectactive directory jenkins plugin+2EPSS score0.95%
It was found that the Active Directory Plugin for Jenkins up to and including version 2.2 did not verify certificates of the Active Directory server, thereby enabling Man-in-the-Middle attacks.CVE-2019-1003009jenkins projectjenkins active directory plugin+2EPSS score0.78%
An improper certificate validation vulnerability exists in Jenkins Active Directory Plugin 2.10 and earlier in src/main/java/hudson/plugins/active_directory/ActiveDirectoryDomain.java, src/main/java/hudson/plugins/active_directory/ActiveDirectorySecurityRealm.java, src/main/java/hudson/plugins/active_directory/ActiveDirectoryUnixAuthenticationProvider.java that allows attackers to impersonate the Active Directory server Jenkins connects to for authentication if Jenkins is configured to use StartTLS.CVE-2026-48918jenkins projectjenkins active directory plugin+2EPSS score0.37%
Jenkins Active Directory Plugin 2.41 and earlier follows LDAP referrals by default.CVE-2026-48919jenkins projectjenkins active directory plugin+2EPSS score0.43%
Jenkins Active Directory Plugin 2.41 and earlier deserializes data from LDAP referrals without validation.CVE-2026-57288jenkins projectjenkins active directory plugin+2EPSS score0.33%
Jenkins Active Directory Plugin 2.41.1 and earlier does not escape the user name before building the LDAP search filter in the Windows native (ADSI) authentication path, allowing unauthenticated attackers to inject LDAP wildcard characters to enumerate directory entries and to authenticate as a matching user whose password they know without knowing their exact user name.CVE-2023-37943jenkins projectjenkins active directory plugin+2EPSS score0.46%
Jenkins Active Directory Plugin 2.30 and earlier ignores the "Require TLS" and "StartTls" options and always performs the connection test to Active directory unencrypted, allowing attackers able to capture network traffic between the Jenkins controller and Active Directory servers to obtain Active Directory credentials.
