ASA-2019-00459 – Atlassian Crowd: pdkinstall development plugin incorrectly enabled

Atlassian Crowd and Crowd Data Center had the pdkinstall development plugin incorrectly enabled in release builds. Attackers who can send unauthenticated or authenticated requests to a Crowd or Crowd Data Center instance can exploit this vulnerability to install arbitrary plugins, which permits remote code execution on systems running a vulnerable version of Crowd or Crowd Data Center

ASA-2019-00426 – Atlassian Jira: Template injection in various resources

There was a server-side template injection vulnerability in Jira Server and Data Center, in the ContactAdministrators and the SendBulkMail actions. For this issue to be exploitable at least one of the following conditions must be met: an SMTP server has been configured in Jira and the Contact Administrators Form is enabled; or an SMTP server has been configured in Jira and an attacker has "JIRA Administrators" access. In the first case, where the Contact Administrators Form is enabled, attackers are able to exploit this issue without authentication. In the second case, attackers with "JIRA Administrators" access can exploit this issue. In either case, successful exploitation of this issue allows an attacker to remotely execute code on systems that run a vulnerable version of Jira Server or Data Center.

ASA-2019-00307 – BitBucket: Path traversal in the migration tool that leads to Remote Code Execution (RCE)

Bitbucket Data Center had a path traversal vulnerability in the Data Center migration tool. A remote attacker with authenticated user with admin permissions 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 Bitbucket Data Center. Bitbucket Server versions without a Data Center license are not vulnerable to this vulnerability.

ASA-2019-00238 – Confluence: Path traversal in the downloadallattachments resource

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 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.
