Directory Traversal in SAP Print Service (SAPSprint)

IdentifiersCVE-2025-42937CWE-35· Path Traversal: '.../...//'

CVE-2025-42937 is a critical path/directory traversal vulnerability in SAP Print Service (SAPSprint) caused by insufficient validation of user-supplied path information. By supplying crafted path values, a remote unauthenticated attacker can traverse to parent directories outside the intended path scope and overwrite files accessible to the SAPSprint process. Public reporting describes the flaw as affecting SAP Print Service deployments that process user-controlled path input without sufficient normalization or validation. The issue is associated with SAP Security Note 3630595. No specific vulnerable version range is provided in the available content.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can allow overwriting of system files reachable by the SAP Print Service process, with high impact to confidentiality, integrity, and availability. Likely consequences include application or host instability, service disruption, destruction or corruption of data, alteration of configuration or executable files, and potential broader system compromise depending on which files can be overwritten and the privileges under which SAPSprint runs.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, restrict network exposure to SAP Print Service so only trusted hosts can reach it, isolate the service from untrusted networks, and monitor for suspicious path patterns and unexpected file modifications. Run SAPSprint with the least privileges possible, limit write access to only required directories, and use host-based controls such as file integrity monitoring to detect attempted overwrite activity.

Remediation

Patch, then assume compromise.

Apply the SAP vendor fix referenced in SAP Security Note 3630595 and the relevant SAP Security Patch Day release. In addition, ensure SAPSprint performs strict canonicalization and validation of user-supplied path input, constrains file operations to an allowlisted directory, and prevents traversal outside intended print/spool paths. Review and reduce filesystem permissions of the SAPSprint service account so it cannot modify sensitive system files unnecessarily.
