An improper input validation vulnerability exists in Jenkins versions 2.106 and earlier, and LTS 2.89.3 and earlier, that allows an attacker to access plugin resource files in the META-INF and WEB-INF directories that should not be accessible, if the Jenkins home directory is on a case-insensitive file system. En el servicio KeyStore, hay una omisión de permisos que permite el acceso a recursos protegidos. Esto podría llevar a un escalado de privilegios local sin necesitar privilegios de ejecución del sistema. No se necesita interacción del usuario para explotarlo.

Jenkins versions 2.56 and earlier as well as 2.46.1 LTS and earlier are vulnerable to an issue in the Jenkins user database authentication realm: create an account if signup is enabled; or create an account if the victim is an administrator, possibly deleting the existing default admin user in the process and allowing a wide variety of impacts. Jenkins, en versiones 2.56 y anteriores y 2.46.1 LTS y anteriores, es vulnerable a un problema en el realm de autenticación de la base de datos de usuarios de Jenkins. La vulnerabilidad permite crear una cuenta si signup está habilitado o crear una cuenta si la víctima es un administrador, lo que podría eliminar durante el proceso al administrador existente por defecto y permitir una gran variedad de impactos. • http://www.securityfocus.com/bid/98062 https://jenkins.io/security/advisory/2017-04-26 • CWE-352: Cross-Site Request Forgery (CSRF) •

Jenkins versions 2.56 and earlier as well as 2.46.1 LTS and earlier are vulnerable to a login command which allowed impersonating any Jenkins user. The `login` command available in the remoting-based CLI stored the encrypted user name of the successfully authenticated user in a cache file used to authenticate further commands. Users with sufficient permission to create secrets in Jenkins, and download their encrypted values (e.g. with Job/Configure permission), were able to impersonate any other Jenkins user on the same instance. Jenkins, en versiones 2.56 y anteriores y 2.46.1 LTS y anteriores, es vulnerable a un comando login que permitía suplantar a cualquier usuario de Jenkins. El comando "login" disponible en la interfaz de línea de comandos basada en remoto almacenaba el nombre de usuario cifrado del usuario autenticado de forma exitosa en un archivo de caché empleado para autenticar más comandos. • http://www.securityfocus.com/bid/98065 https://jenkins.io/security/advisory/2017-04-26 • CWE-287: Improper Authentication •

Jenkins versions 2.56 and earlier as well as 2.46.1 LTS and earlier are vulnerable to an XStream: Java crash when trying to instantiate void/Void. Jenkins, en versiones 2.56 y anteriores y 2.46.1 LTS y anteriores, es vulnerable al cierre inesperado de Java XStream: al intentar crear una instancia void/Void. • http://www.securityfocus.com/bid/98066 https://jenkins.io/security/advisory/2017-04-26 • CWE-502: Deserialization of Untrusted Data •

The Jenkins 2.73.1 and earlier, 2.83 and earlier remote API at /job/(job-name)/api contained information about upstream and downstream projects. This included information about tasks that the current user otherwise has no access to, e.g. due to lack of Item/Read permission. This has been fixed, and the API now only lists upstream and downstream projects that the current user has access to. La API remota de Jenkins 2.73.1 y anteriores y 2.83 y anteriores en /job/(job-name)/api contenía información sobre los proyectos de subida y bajada. Esto incluía información sobre tareas que, de otra forma, no son accesibles para el usuario actual, por ejemplo, debido a la falta de permisos Item/Read. • https://jenkins.io/security/advisory/2017-10-11 • CWE-862: Missing Authorization •
