Affected versions of Atlassian Jira Server and Data Center allow remote attackers with administrator privileges to execute arbitrary code via a Remote Code Execution (RCE) vulnerability in the Email Templates feature. This issue bypasses the fix of https://jira.atlassian.com/browse/JSDSERVER-8665. The affected versions are before version 8.13.15, and from version 8.14.0 before 8.20.3.

According to its self-reported version number, the instance of Atlassian Jira hosted on the remote web server is prior to 8.13.15 or 8.14.x prior to 8.20.3. It is, therefore, affected by a vulnerability allowing remote attackers with administrator permissions to execute arbitrary code via Template Injection leading to Remote Code Execution (RCE) in the Email Templates feature.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

According to its self-reported version number, the instance of Atlassian Jira hosted on the remote web server is prior to 8.13.15 or 8.14.x prior to 8.20.3. It is, therefore, affected by multiple vulnerabilities:

 - A template injection leading to remote code execution in the Email Templates feature allowing remote attackers with administrator permissions to execute arbitrary code.

 - A reflected Cross-Site Scripting (XSS) vulnerability in the /rest/collectors/1.0/template/custom endpoint allowing remote attackers to inject arbitrary HTML or JavaScript.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

According to its self-reported version number, the instance of Atlassian Jira hosted on the remote web server is affected by a remote code execution vulnerability in its email template feature. An authenticated, remote attacker can exploit this to bypass authentication and execute arbitrary commands. 

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version   number.
