Knowledge Base
Description
Oracle Weblogic Server v10.3.6.0, v12.1.3.0, v12.2.1.2, and v12.2.1.3 are vulnerable to a deserialization vulnerable, which can be used to execute code on vulnerable systems. An unauthenticated user with network access via T3 could exploit the vulnerability. This module has been tested against Oracle Weblogic Server v10.3.6.0 running on Windows10 x64 using JDK v7u17.
Vulnerable Application
Oracle Weblogic Server v10.3.6.0, v12.1.3.0, v12.2.1.2, and v12.2.1.3.
