Severity: Medium

 

Summary: Tableau Prep does not properly validate filenames when opening a maliciously-crafted Packaged Tableau Flow File (.tflx). The resulting files can be written outside of the intended temporary location.

 

Impact: A Tableau Prep user who opens a maliciously-crafted Tableau Flow File can unknowingly write and overwrite files to any location the user has access to.

 

Vulnerable Versions:  The following versions have this vulnerability:

Tableau Prep: 2018.1 through 2018.1.2

 

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

Tableau Prep: 2018.2.1

Severity: Medium

 

Summary: Changing the log level to "debug" exposes datasource credentials in plaintext in the application logs. The log files are stored in an access-controlled location. On Tableau Desktop, access to Tableau application logs is limited to the current user. On Tableau Server, application logs are stored with permission that is restricted to the local administrator.

 

By default, the log level is set to "info".

 

Impact: An attacker with access to the application logs can learn the datasource credentials.

 

Vulnerable Versions:  The following versions have this vulnerability:

Tableau Desktop: 2018.1 through 2018.1.2

Tableau Server on Windows: 2018.1 through 2018.1.2

Tableau Server on Linux: 2018.1 through 2018.1.2

 

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

Tableau Desktop: 2018.1.3

Tableau Server on Windows: 2018.1.3

Tableau Server on Linux: 2018.1.3

Severity: Informational

 

Summary: When connecting to a datasource using Web Authoring in Tableau Server and Tableau Online, the “Require SSL” checkbox is not persisted when the workbook is saved. If the datasource has SSL and non-SSL connections enabled, the workbook will connect to the datasource without using SSL.

 

On Tableau Desktop, the “Require SSL” checkbox is persisted to the workbook and operates as intended when the workbook is opened in Desktop and when it is published to Tableau Server or Tableau Online.

 

Impact: Workbooks that are intended to connect to a datasource over SSL do not use SSL and instead connect over plaintext.

 

Vulnerable Versions:  The following versions have this vulnerability:

Tableau Server on Windows: 2018.1.1

Tableau Server on Linux: 2018.1.1

 

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

Tableau Server on Windows: 2018.1.2

Tableau Server on Linux: 2018.1.2

Severity: Medium

 

Summary: The tabcmd utility logs all commands and their parameters to a local log file. When sensitive parameters are given, such as the password parameter used to authenticate to Tableau Server the value is written to the log in plaintext.

 

Impact: Malicious users with access to the tabcmd logs can access passwords that are used for authenticating to Tableau Server.

More information: NIST CVE-2018-2783

Severity: Medium

 

Summary: Tableau Services Manager (TSM) CLI logs all commands and their parameters to a local log file. When sensitive parameters are given, such as the password parameter used to authenticate to TSM, the value is written to the log in plaintext.

The TSM CLI component is included Tableau Server on Linux.  Tableau Server on Windows is not affected by this vulnerability.

 

Impact: Malicious users with access to the TSM CLI logs can access passwords that are used for authenticating Tableau Server Manager.

 

Vulnerable Versions:  The following versions have this vulnerability:

Tableau Server for Linux 10.5 (through 10.5.4)

Tableau Server on Linux 2018.1 (through 2018.1.1)

 

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

Tableau Server on Linux 10.5.5

Tableau Server on Linux 2018.1.2

 

Acknowledgements: This issue was reported to Tableau by Paul Grimshaw (Totally Techy)

Severity: Medium

 

Summary: The authentication mechanism on the internal REST service that is used by Tableau Prep can be bypassed. The REST service runs only while Tableau Prep is being used. Since the REST service only listens on localhost, an attacker would have to have access to execute code on the host to exploit this vulnerability. In the remote case, a user would have to visit a malicious website that exploits the vulnerability.

 

Impact: An attacker that can make calls to the REST service can read data from the datasources that Tableau Prep is connected to.

 

Vulnerable Versions:  The following versions have this vulnerability:

Tableau Prep through 2018.1 through 2018.1.1

 

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

Tableau Prep 2018.1.2 or later

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
Tableau Server on Windows through 9.3.21

  • Tableau Server on Windows 10.4.x
  • Tableau Server on Windows 10.5.x
  • Tableau Server on Windows 2018.1

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:
