Detailed vulnerability description

The vulnerability allows a remote attacker to compromise the affected application.

The vulnerability exists due to a Polymorphic Typing issue when processing JSON requests  within the com.p6spy.engine.spy.P6DataSource component. A remote attacker can send specially crafted JSON data to an RMI service endpoint and execute arbitrary code on he system.

Successful exploitation of the vulnerability requires that Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint, the service has has the p6spy (3.8.6) jar in the classpath, and an attacker can find an RMI service endpoint to send requests to.
