Description


Marc Schoenefeld has reported a weakness in JBoss, which can be exploited by malicious people to disclose system information.

The weakness is caused due to an error in the request handling for RMI code download in the "org.jboss.web.WebServer" class. This can be exploited to disclose the full path to the installation directory or the contents of certain configuration files (e.g. the security policy file) by sending a specially crafted HTTP request with a path starting with "%" to port 8083.

The weakness has been reported in versions 3.2.2 through 3.2.7 and 4.0.2. Other versions may also be affected.


Solution:
The vendor recommends restricting file downloads via the RMI Dynamic ClassLoading Service.
