Multiple cross-site scripting (XSS) vulnerabilities in the Web Console in the Application Server in Red Hat JBoss Enterprise Application Platform (aka JBoss EAP or JBEAP) 4.2.0 before 4.2.0.CP08, 4.2.2GA, 4.3 before 4.3.0.CP07, and 5.1.0GA allow remote attackers to inject arbitrary web script or HTML via the (1) monitorName, (2) objectName, (3) attribute, or (4) period parameter to createSnapshot.jsp, or the (5) monitorName, (6) objectName, (7) attribute, (8) threshold, (9) period, or (10) enabled parameter to createThresholdMonitor.jsp. NOTE: some of these details are obtained from third party information.

The default configuration of the JBossAs component in Red Hat JBoss Enterprise Application Platform (aka JBossEAP or EAP), possibly 4.2 before CP04 and 4.3 before CP02, when a production environment is enabled, sets the DownloadServerClasses property to true, which allows remote attackers to obtain sensitive information (non-EJB classes) via a download request, a different vulnerability than CVE-2008-3273.
