This module exploits a vulnerability in Microsoft Office Word. The flaw is related in how Microsoft Word handles OleLink objects. It is possible to open a RTF file and execute arbitrary code in vulnerables installations of Microsoft Office Word. This vulnerability was originally seen being exploited in the wild starting in October 2016.
An unauthenticated remote code execution vulnerability allowed attackers to transfer a serialized Java object to the Jenkins CLI, making Jenkins connect to an attacker-controlled LDAP server, which in turn can send a serialized payload leading to code execution, bypassing existing protection mechanisms. This can be exploited by malicious local attackers to gain SYSTEM privileges on Windows targets.
