Detailsinfo

A vulnerability classified as problematic was found in Keyfactor SignServer up to 7.5.x. Affected by this vulnerability is some unknown functionality of the component SignerStatusReportWorker. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

This vulnerability is known as CVE-2026-25825 since 02/06/2026. The exploitation appears to be easy. The attack can be launched remotely. The exploitation requires an enhanced level of successful authentication. Neither technical details nor an exploit are publicly available.
