Highest overall severity: High

 

Summary:

Workbooks connected to published data sources that leverage user functions may not properly filter data the first time a view is loaded due to a caching issue.

 

Impact:

A user with access to a published workbook or data source can see unfiltered data for another user resulting in information disclosure within that same workbook. A malicious user cannot directly force this to happen.

 

Products and Versions: Tableau Server | Tableau Desktop | Tableau Bridge | Tableau Prep | Tableau Reader | Tableau Mobile | Tableau Public Desktop

Tableau Server

Severity: High CVSS3 Score: AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N/CR:H - 7.5 High

Product specific notes:

This vulnerability affects the user filter functionality of Tableau server.

 

If you have already installed Tableau Server 2019.1.0 and plan to upgrade to 2019.1.1, you will need to take the following steps before you upgrade to ensure your cache is properly cleared:

tsm stop

tsm maintenance cleanup -r

install the new version 2019.1.1 and initiate the upgrade script to complete the upgrade.

 

If you have already installed Tableau Server 2019.1.0 and do not plan to upgrade to 2019.1.1, you will need to take the following steps to ensure your cache is properly cleared and the logical query cache is disabled:

tsm stop

tsm maintenance cleanup -r

tsm configuration set -k features.LogicalQueryCache -v false

tsm pending-changes apply

tsm start

Summary: The ziplogs command (tsm maintenance ziplogs) is used by Tableau Server administrators to package configuration information and log files to send to Tableau Support. Unneeded, but sensitive information is contained in these zip archives.

 

Impact: Running the ziplogs command on a Tableau Server that is configured with external SSL will generate an archive file that includes the private key for the external SSL certificate.

Summary: A malicious workbook that has a refresh job scheduled on it can cause the Backgrounder service to crash and fail to process any subsequent jobs.

 

Impact: The Backgrounder service will repeatedly crash and no new jobs will be processed.

 

Vulnerable Versions:  The following versions have this vulnerability:

Tableau Server 2018.2.0 through 2018.2.3

Tableau Server 2018.3.0

Tableau Server on Linux 2018.2.0 through 2018.2.3

Tableau Server 2018.3.1

Tableau Server on Linux 2018.2.4

Tableau Server on Linux 2018.3.1

Severity: Medium

 

Summary: The cookie used to identify the Tableau Services Manager (TSM) Web UI session does not expire if a browser window to the web interface remains open.

 

Impact: This vulnerability increases the risk that an unattended computer where the TSM web UI is left open will host a valid session. The open valid session allows users to perform administrative actions on the Tableau Server installation.

 

Vulnerable Versions:  The following versions have this vulnerability:

Tableau Server 2018.2.0 through 2018.2.3

Tableau Server 2018.3.0

Tableau Server on Linux 2018.2.0 through 2018.2.3

Tableau Server 2018.2.4

Tableau Server 2018.3.1

Tableau Server on Linux 2018.2.4

Tableau Server on Linux 2018.3.1

Severity: High

 

Summary: This vulnerability requires that a malicious user embeds specific parameters in a Tableau workbook. The malicious user must also have rights to publish the workbook on Tableau Server. Alternatively, the malicious user must convince a victim to open the affected workbook in Tableau Desktop.

 

Impact: A memory corruption error can occur. This memory corruption might result in arbitrary code execution or a crash.

 

Vulnerable Versions:  The following versions have this vulnerability:

Tableau Server 2018.3.0

Tableau Server on Linux 2018.3.0

 

Tableau Desktop 2018.3.0

 

 

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

Tableau Server 2018.3.1

Tableau Server on Linux 2018.3.1

 

Tableau Desktop 2018.3.1

Severity: Medium

 

Summary: Tableau Server and Tableau Desktop may misinterpret part of a password as a delimiter and fail to remove the entire password when writing log statements. Tableau writes logs to access-controlled areas of the files system.

 

Impact: A password used to connect with an ODBC-based connector may result in partial password disclosure. If the password contains one or more certain special characters, Tableau will interpret the characters as delimiters. In this case, a portion of the password will be written in cleartext to the application logs. An attacker with access to these log files will have access to a portion of the password, thereby increasing the probability of a successful brute-force attack on the database.

Summary: This vulnerability requires that a malicious user embeds specific parameters in a Tableau workbook. The malicious user must also have rights to publish the workbook on Tableau Server. The malicious user must then construct a specially crafted URL to enable arbitrary javascript to run in the victim's browser at run time.

 

Impact: When users open the modified workbook via the specially crafted URL, arbitrary javascript can run in their browser session.

Summary: A Tableau Server configured with “External SSL” enabled that receives a specially crafted HTTP request on the non-SSL port will respond with a redirect to the HTTPS port. The redirect will specify the local IP address of the host rather than the hostname.

 

Impact: An internal IP address of the Tableau Server host will be exposed. For Tableau Server instances running on the internet, this vulnerability can expose details of the internal network topology to outside users.

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

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.
