A new exploit has emerged that leverages two critical, now-patched vulnerabilities in SAP NetWeaver, putting organizations at significant risk of system compromise and data theft. This exploit chains CVE-2025-31324 and CVE-2025-42999 to bypass authentication and enable remote code execution, according to SAP security firm Onapsis.
- CVE-2025-31324 (CVSS score: 10.0) – Lacks authorization checks in SAP NetWeaver’s Visual Composer development server
- CVE-2025-42999 (CVSS score: 9.1) – Vulnerability due to insecure deserialization in the same server
These vulnerabilities were patched by SAP in April and May 2025, but not before they were exploited as zero-days by threat actors as early as March. Multiple ransomware and data extortion groups, including Qilin, BianLian, and RansomExx, have been seen exploiting these flaws, along with several espionage groups linked to China targeting critical infrastructures.
