This issue exists to document that a security improvement in the way that Jira Server and Data Center use velocity templates has been implemented. The way in which velocity templates were used in Atlassian Jira Server and Data Center in affected versions allowed remote attackers to achieve remote code execution via insecure deserialization, if they were able to exploit a server side template injection vulnerability. The affected versions are before version 7.13.0, from version 8.0.0 before 8.5.0, and from version 8.6.0 before version 8.8.1.

Affected versions of Atlassian Jira Server and Data Center allow remote attackers to execute arbitrary code via a DLL hijacking vulnerability in Tomcat. The affected versions are before version 8.5.5, and from version 8.6.0 before 8.7.2.

The /rest/jira-ril/1.0/jira-rest/applinks resource in the crucible-jira-ril plugin in Atlassian Fisheye and Crucible before version 4.8.1 allows remote attackers to get information about any configured Jira application links via an information disclosure vulnerability.

The review resource in Atlassian Fisheye and Crucible before version 4.8.1 allows remote attackers to inject arbitrary HTML or Javascript via a cross site scripting (XSS) vulnerability through the review objectives.

The /profile/deleteWatch.do resource in Atlassian Fisheye and Crucible before version 4.8.1 allows remote attackers to remove another user's watching settings for a repository via an improper authorization vulnerability.

The /json/fe/activeUserFinder.do resource in Altassian Fisheye and Crucible before version 4.8.1 allows remote attackers to view user user email addresses via a information disclosure vulnerability.

The file editing functionality in the Atlassian Companion App before version 1.0.0 allows local attackers to have the app run a different executable in place of the app's cmd.exe via a untrusted search path vulnerability.

The setup resources in Atlassian Fisheye and Crucible before version 4.8.1 allows remote attackers to complete the setup process via a cross-site request forgery (CSRF) vulnerability.

The /plugins/servlet/jira-blockers/ resource in the crucible-jira-ril plugin in Atlassian Fisheye and Crucible before version 4.8.1 allows remote attackers to get the ID of configured Jira application links via an information disclosure vulnerability.

The file downloading functionality in the Atlassian Companion App before version 1.0.0 allows remote attackers, who control a Confluence Server instance that the Companion App is connected to, execute arbitrary .exe files via a Protection Mechanism Failure.
