Severity:  Critical

 

Summary: Some versions of Tableau Server contain a vulnerability that allows a malicious user with publishing privileges to publish a workbook that runs malicious code. The vulnerability allows the code to run with the security privileges of the Tableau Server service account ("Run As User" account on Windows and the "tableau" system user on Linux). Deployments that allow untrusted publishers or use sites to enforce security policies are at highest risk from this vulnerability.

 

Tableau Desktop is also vulnerable, which can be exploited when a user opens a maliciously crafted workbook. 

 

Tableau Online and the Tableau Public community platform are not affected by this vulnerability.

 

Impact:  Remote code execution that could impact the confidentiality, integrity, and availability of Tableau Server.  This vulnerability could allow a malicious user hosted on one site of a Tableau Server instance to compromise another site that is hosted on the same computer.

 

On Tableau Desktop, the vulnerability could result in the execution of malicious code that could impact confidentiality, integrity, and availability of the computer running Tableau Desktop. In the Desktop scenario, the code runs in the security context of the user who opens the compromised workbook.
