Opened: Nov 27, 2019
Severity: 3-Major

Symptoms

When a form is received in the response, TMM crashes when SSO identifies the form parameter, and logs the Form parameter value and type in SSOv2 form-based passthrough log.

Impact

TMM crash when Passthrough mode is enabled in SSO. Traffic disrupted while tmm restarts.

Conditions

-- When any of the form parameters that SSO receives in the response does not have a value. -- Passthrough mode is enabled in SSO.

Workaround

Do not use Passthrough mode with SSO.

Fix Information

TMM does not crash when Passthrough mode is enabled in SSO, and SSO receives any valid form in a response.
