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 TSMCLI 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.
