Description
The vulnerability allows a remote unauthenticated attacker to execute arbitrary code on the target system.

The weakness exists in the File Upload servlet due to improper input validation of the parameters in the HTTP request and a processing error in the role-based access control (RBAC) of URLs. A remote attacker can upload a specially crafted Java Server Pages (JSP) file to a specific folder using path traversal techniques and then execute that file remotely and execute arbitrary code with the privileges of the SYSTEM user.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation
Update to versions 11.0(0.238)S0, 10.3(1)S5, 10.3(1)R(0.21), 10.3(0.122)S0, 8.3(0)SK(0.62), 8.3(0)SK(0.32), 8.2(0.26)S0 or 8.2(0)SK(0.221).
