Jenkins 2.73.1 and earlier, 2.83 and earlier users with permission to create or configure agents in Jenkins could configure a launch method called 'Launch agent via execution of command on master'. This allowed them to run arbitrary shell commands on the master node whenever the agent was supposed to be launched. Configuration of this launch method now requires the Run Scripts permission typically only granted to administrators. Los usuarios de Jenkins 2.73.1 y anteriores y 2.83 y anteriores con permiso para crear o configurar agentes podrían configurar un método de inicio llamado "Launch agent via execution of command on master". Esto les permitía ejecutar comandos shell arbitrarios en el nodo del servidor maestro cada vez que se supone que se iba a iniciar el agente. • https://jenkins.io/security/advisory/2017-10-11 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

A race condition during Jenkins 2.94 and earlier; 2.89.1 and earlier startup could result in the wrong order of execution of commands during initialization. There is a very short window of time after startup during which Jenkins may no longer show the 'Please wait while Jenkins is getting ready to work' message but Cross-Site Request Forgery (CSRF) protection may not yet be effective. Una condición de carrera durante el inicio de Jenkins 2.94 y anteriores y 2.89.1 y anteriores podría desembocar en un orden incorrecto de ejecución de comandos durante el proceso de inicialización. Hay muy poco espacio de tiempo tras el inicio, durante el cual Jenkins podría no mostrar más el mensaje "Please wait while Jenkins is getting ready to work", pero la protección Cross-Site Request Forgery (CSRF) tal vez no sea efectiva todavía. • https://jenkins.io/security/advisory/2017-12-14 • CWE-352: Cross-Site Request Forgery (CSRF) •

Jenkins through 2.93 allows remote authenticated administrators to conduct XSS attacks via a crafted tool name in a job configuration form, as demonstrated by the JDK tool in Jenkins core and the Ant tool in the Ant plugin, aka SECURITY-624. Jenkins hasta la versión 2.93 permite que administradores remotos no autenticados lleven a cabo ataques de XSS mediante un nombre de herramienta manipulado en un formulario de configuración de trabajos, tal y como demuestra la herramienta JDK en Jenkins core y la herramienta Ant en el plugin Ant. Esto también se conoce como SECURITY-624. • http://vsintelli.com/portal/blog/23-security-advisory-2017-12-04 http://www.securityfocus.com/bid/102130 https://jenkins.io/security/advisory/2017-12-05 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

Jenkins before 1.586 does not set the HttpOnly flag in a Set-Cookie header for session cookies when run on Tomcat 7.0.41 or later, which makes it easier for remote attackers to obtain potentially sensitive information via script access to cookies. Jenkins en versiones anteriores a la 1.586 no establece el indicador "HttpOnly" en un encabezado Set-Cookie para cookies de sesión cuando se ejecuta en Tomcat 7.0.41 o siguientes, lo que facilita que los atacantes remotos obtengan información potencialmente sensible mediante el acceso del script a las cookies. • http://www.openwall.com/lists/oss-security/2015/01/22/3 http://www.securityfocus.com/bid/72054 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=769682 https://bugzilla.redhat.com/show_bug.cgi?id=1185151 https://github.com/jenkinsci/jenkins/commit/582128b9ac179a788d43c1478be8a5224dc19710 https://issues.jenkins-ci.org/browse/JENKINS-25019 https://jenkins.io/changelog-old • CWE-254: 7PK - Security Features •

Jenkins before 1.586 does not set the secure flag on session cookies when run on Tomcat 7.0.41 or later, which makes it easier for remote attackers to capture cookies by intercepting their transmission within an HTTP session. Jenkins en versiones anteriores a la 1.586 no establece el indicador "secure" cuando se ejecuta en Tomcat 7.0.41 o posterior, lo que facilita que los atacantes remotos capturen cookies interceptando su transmisión en una sesión HTML. • http://www.openwall.com/lists/oss-security/2015/01/22/3 http://www.securityfocus.com/bid/72054 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=769682 https://bugzilla.redhat.com/show_bug.cgi?id=1185148 https://github.com/jenkinsci/jenkins/commit/582128b9ac179a788d43c1478be8a5224dc19710 https://issues.jenkins-ci.org/browse/JENKINS-25019 https://jenkins.io/changelog-old • CWE-254: 7PK - Security Features •
