Description

An issue was discovered in Keyfactor SignServer before 7.6.0. The output file to which SignerStatusReportWorker logs the report can be set to any path, even one that points to a file that already exists. This gives a user (with admin access) the possibility to write files in arbitrary directories in the server filesystem and potentially overwrite files accessible by the local user JBoss.
