Description

AI Translation Available

An error in the SignServer container startup logic was found in Keyfactor SignServer versions prior to 7.2. The Admin CLI command used to configure Certificate access to the initial startup of the container sets a property of 'allowany' to allow any user with a valid and trusted client auth certificate to connect. Admins can then set more restricted access to specific certificates. A logic error caused this admin CLI command to be run on each restart of the container instead of only the first startup as intended resetting the configuration to 'allowany'.
