In Jboss Application Server as shipped with Red Hat Enterprise Application Platform 5.2, it was found that the doFilter method in the ReadOnlyAccessFilter of the HTTP Invoker does not restrict classes for which it performs deserialization and thus allowing an attacker to execute arbitrary code via crafted serialized data.

An Elevated Privileges issue exists in JBoss AS 7 Community Release due to the improper implementation in the security context propagation, A threat gets reused from the thread pool that still retains the security context from the process last used, which lets a local user obtain elevated privileges.

DISPUTED The Embedded Jopr component in JBoss Application Server includes the cleartext datasource password in unspecified HTML responses, which might allow (1) man-in-the-middle attackers to obtain sensitive information by leveraging failure to use SSL or (2) attackers to obtain sensitive information by reading the HTML source code. NOTE: the vendor says that this does not cross a trust boundary and that it is recommended best-practice that SSL is configured for the administrative console.

A DOM based cross-site scripting flaw was found in the JBoss Application Server 7 before 7.1.0 Beta 1 administration console. A remote attacker could provide a specially-crafted web page and trick the valid JBoss AS user, with the administrator privilege, to visit it, which would lead into the DOM environment modification and arbitrary HTML or web script execution.

We have received information from a third party regarding vulnerabilities in JBoss Application Server.

Input passed to the "monitorName", "objectName", "attribute", and "period" parameters in createSnapshot.jsp and to the "monitorName", "objectName", "attribute", "threshold", "period", and "enabled" parameters in createThresholdMonitor.jsp of the JBoss Web Console is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

The vulnerabilties are confirmed in version 5.1.0GA. Other versions may also be affected.

The preliminary disclosure date has been set to July 22th, 2009.

HTTPServerILServlet.java in JMS over HTTP Invocation Layer of the JbossMQ implementation (jbossmq-httpil.sar, which is enabled by default in Red Hat Jboss Applicatino Server <= Jboss 4.X) does not restrict the classes for which it performs deserialization, which allows remote attackers to execute arbitrary code via crafted serialized data.
