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.

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 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 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 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 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 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 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 Axis 1.4 and earlier, as used in PayPal Payments Pro, PayPal Mass Pay, PayPal Transactional Information SOAP, the Java Message Service implementation in Apache ActiveMQ, and other products, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.
