HTTP: Apache Unomi Context.js Remote Code Execution
This signature detects attempts to exploit a known vulnerability against Apache Unomi. A successful attack can lead to arbitrary code execution.
Extended Description
It is possible to inject malicious OGNL or MVEL scripts into the /context.json public endpoint. This was partially fixed in 1.5.1 but a new attack vector was found. In Apache Unomi version 1.5.2 scripts are now completely filtered from the input. It is highly recommended to upgrade to the latest available version of the 1.5.x release to fix this problem.
