Summary

CVE-2025-42950 is a critical-severity Code Injection (CWE-94) vulnerability in Sap (inferred from references). Its CVSS base score is 9.9 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 39.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

CVE-2025-42950 is a critical vulnerability in SAP Landscape Transformation (SLT), affecting a function module exposed via RFC. The flaw allows an attacker with user privileges to inject arbitrary ABAP code into the system, bypassing essential authorization checks. Rated at CVSS 9.9 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H) and mapped to CWE-94 (Code Injection), it effectively acts as a backdoor, posing risks to the confidentiality, integrity, and availability of the affected SAP system.

An attacker requires low-privilege user credentials with network access to the SLT component. Exploitation involves invoking the vulnerable RFC-exposed function module to inject and execute arbitrary ABAP code, enabling full system compromise without user interaction. Successful attacks can lead to unauthorized data access, modification, or deletion, as well as disruption of system services.

Mitigation details are provided in SAP Note 3633838 and the SAP Security Patch Day advisory at the referenced URLs, which outline patches and remediation steps for affected systems.
