An arbitrary file write was found in Keyfactor SignServer versions prior to 7.3.2. The properties ARCHIVETODISKFILENAME-PATTERN, ARCHIVETODISKPATHBASE, ARCHIVETODISKPATH_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.
