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.

 

Vulnerable Versions: The following versions of Tableau Server and Tableau Desktop (including Tableau Desktop Public Edition and Tableau Reader) are vulnerable:

Tableau Server on Linux through 10.5.3
Tableau Server on Linux through 2018.1.0


Tableau Server on Windows through 9.2.23

Severity: Medium

 

Summary: Tableau Services Manager (TSM) passes a sensitive value via the command line during node initialization.

 

TSM is included with Tableau Server on Linux.  Tableau Server on Windows in not affected by this vulnerability.

 

Impact: Malicious users with access to the host and the ability to view the process list, could view process attributes, including the TSM administrator password.

 

Vulnerable Versions:  The following versions have this vulnerability:

Tableau Server on Linux 2018.1 (through 2018.1.0).

 

Resolution: The issue can be fixed by upgrading to the following version:

Tableau Server on Linux 2018.1.1

Severity: High

 

Summary: An authenticated remote attacker can send a specially crafted message that can result in the disclosure of information from Tableau Server. The scope of the disclosure of information is bound by access privileges of the Tableau Server service account. For more information about Tableau Server service account, see the online documentation (Windows | Linux).

 

Impact: Exploits of the authenticated API call can result in the disclosure of information for any local file that the Tableau Server service account can read.

 

Vulnerable Versions:  The following versions have this vulnerability:

Tableau Server: 9.2 through 9.2.23 

Tableau Server: 9.3 through 9.3.21

Tableau Server on Linux: 2018.1.1

Severity: High

 

Summary: The 'readonly' and 'tableau' users in the repository are intended to have limited access to the tables in the repository. See "Collect Data with the Tableau Server Repository" (Windows | Linux).

 

By default, these accounts have access to tables in the repository. This vulnerability exposes write-access to two tables in the repository that may contain workbook information.

 

Impact: Malicious users with access to the 'readonly' or 'tableau' repository accounts can access datasources that are embedded in published workbooks. Malicious users may also modify the contents of workbooks stored in the vulnerable tables.

 

Mitigation: Disable access to the repository for the 'readonly' and 'tableau' user accounts:
