The Widget Connector macro in Atlassian Confluence Server before version 6.6.12 (the fixed version for 6.6.x), from version 6.7.0 before 6.12.3 (the fixed version for 6.12.x), from version 6.13.0 before 6.13.3 (the fixed version for 6.13.x), and from version 6.14.0 before 6.14.2 (the fixed version for 6.14.x), allows remote attackers to achieve path traversal and remote code execution on a Confluence Server or Data Center instance via server-side template injection.

Confluence Server and Data Center had a path traversal vulnerability in the downloadallattachments resource. A remote attacker who has permission to add attachments to pages and / or blogs or to create a new space or a personal space or who has 'Admin' permissions for a space can exploit this path traversal vulnerability to write files to arbitrary locations which can lead to remote code execution on systems that run a vulnerable version of Confluence Server or Data Center. All versions of Confluence Server from 2.0.0 before 6.6.13 (the fixed version for 6.6.x), from 6.7.0 before 6.12.4 (the fixed version for 6.12.x), from 6.13.0 before 6.13.4 (the fixed version for 6.13.x), from 6.14.0 before 6.14.3 (the fixed version for 6.14.x), and from 6.15.0 before 6.15.2 are affected by this vulnerability.

The WebDAV endpoint in Atlassian Confluence Server and Data Center before version 6.6.7 (the fixed version for 6.6.x), from version 6.7.0 before 6.8.5 (the fixed version for 6.8.x), and from version 6.9.0 before 6.9.3 (the fixed version for 6.9.x) allows remote attackers to send arbitrary HTTP and WebDAV requests from a Confluence Server or Data Center instance via Server-Side Request Forgery.

There was a local file disclosure vulnerability in Confluence Server and Confluence Data Center via page exporting. An attacker with permission to editing a page is able to exploit this issue to read arbitrary file on the server under <install-directory>/confluence/WEB-INF directory, which may contain configuration files used for integrating with other services, which could potentially leak credentials or other sensitive information such as LDAP credentials. The LDAP credential will be potentially leaked only if the Confluence server is configured to use LDAP as user repository. All versions of Confluence Server from 6.1.0 before 6.6.16 (the fixed version for 6.6.x), from 6.7.0 before 6.13.7 (the fixed version for 6.13.x), and from 6.14.0 before 6.15.8 (the fixed version for 6.15.x) are affected by this vulnerability.
