An arbitrary file write was found in Keyfactor SignServer versions prior to 7.3.2. The properties ARCHIVETODISK_FILENAME-PATTERN, ARCHIVETODISK_PATH_BASE, ARCHIVETODISK_PATH_PATTERN can be set to any path, even ones that will point to files that already exist. This vulnerability gives a user with admin access the possibility to write files in arbitrary directories in the server file system and potentially overwrite files accessible by the local user JBoss.

Keyfactor SignServer before 7.3.1 has Incorrect Access Control, issue 2 of 3.
