Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly addresses the insufficient validation of user-provided path information to prevent directory traversal and unauthorized file overwrites.

SI-2 Flaw Remediation good match

prevent

Mandates timely identification, reporting, and correction of flaws like this critical directory traversal vulnerability through patching as recommended in SAP security notes.

SI-7 Software, Firmware, and Information Integrity partial match

detect

Provides integrity monitoring to detect unauthorized overwrites of system files resulting from successful directory traversal exploitation.

Why these techniques?

The vulnerability is a path traversal in SAP Print Service allowing unauthenticated remote attackers to overwrite system files, directly enabling exploitation of a public-facing application.

Confidence: HIGH · MITRE ATT&CK Enterprise v19.0

NVD Description

SAP Print Service (SAPSprint) performs insufficient validation of path information provided by users. An unauthenticated attacker could traverse to the parent directory and over-write system files causing high impact on confidentiality integrity and availability of the application.

Deeper analysisAI

CVE-2025-42937 is a critical directory traversal vulnerability in SAP Print Service (SAPSprint), stemming from insufficient validation of user-provided path information (CWE-35). This flaw allows attackers to access parent directories and overwrite system files, with a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), highlighting its potential for high impact on confidentiality, integrity, and availability.

An unauthenticated attacker can exploit this vulnerability remotely over the network with low attack complexity and no user interaction or privileges required. By supplying specially crafted path data to SAPSprint, the attacker can traverse directories and overwrite critical system files, enabling full compromise of the affected application.

SAP has published mitigation details in security note 3630595 at https://me.sap.com/notes/3630595, as part of their SAP Security Patch Day resources at https://url.sap/sapsecuritypatchday. Security practitioners should review these advisories and apply the provided patches immediately to affected systems.
