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.
