The Jetty ResourceHandler in Apache ActiveMQ 5.x before 5.3.2 and 5.4.x before 5.4.0 allows remote attackers to read JSP source code via a // (slash slash) initial substring in a URI for (1) admin/index.jsp, (2) admin/queues.jsp, or (3) admin/topics.jsp.

Apache ActiveMQ before 5.6.0 allows remote attackers to cause a denial of service (file-descriptor exhaustion and broker crash or hang) by sending many openwire failover:tcp:// connection requests.

Apache ActiveMQ is vulnerable to a denial of service, caused by the enablement of a sample web application by the default configuration. By sending specially-crafted HTTP requests, an attacker could exploit this vulnerability to consume broker resources and cause a denial of service.

Apache ActiveMQ is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by multiple vectors. A remote attacker could exploit this vulnerability using various parameters in a specially-crafted URL to execute script in a victim's Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.

Apache ActiveMQ is vulnerable to a denial of service, caused by the failure to require authentication, by the Web console. By sending specially-crafted HTTP requests, an attacker could exploit this vulnerability to obtain sensitive information or cause a denial of service.

Apache ActiveMQ is vulnerable to cross-site scripting, caused by improper validation of user-supplied input when handling cron jobs. A remote attacker could exploit this vulnerability using specific parameters to inject malicious script into a Web page which would be executed in a victim's Web browser within the security context of the hosting Web site, once the page is viewed. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.

Apache ActiveMQ is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the demo/portfolioPublish script. A remote attacker could exploit this vulnerability using the refresh parameter in a specially-crafted URL to execute script in a victim's Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.

Apache ActiveMQ is vulnerable to cross-site scripting, caused by improper validation of user-supplied input. A remote attacker could exploit this vulnerability using a specially-crafted URL to execute script in a victim's Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.

Apache ActiveMQ is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the web based administration console. A remote attacker could exploit this vulnerability using a specially-crafted URL to execute script in a victim's Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.

Apache ActiveMQ could allow a remote attacker to hijack the clicking action of the victim, caused by the failure to set the X-Frame-Options header in HTTP responses by the Administrative Web console. By persuading a victim to visit a malicious Web site, a remote attacker could exploit this vulnerability to hijack the victim's click actions.
