SAP issues patches for NetWeaver deserialization RCE

🔒 SAP has released security updates addressing 13 vulnerabilities, including a maximum-severity insecure deserialization flaw in NetWeaver AS Java (CVE-2025-42944, CVSS 10.0) that can lead to arbitrary OS command execution via the RMI‑P4 module. The vendor's latest patch adds a JVM-wide serial filter (jdk.serialFilter) to block dangerous classes and packages — a list curated with the ORL and recommended by security firm Onapsis — and complements an earlier remediation issued last month. Other critical fixes include a directory traversal in SAP Print Service (CVE-2025-42937, 9.8) and an unrestricted file upload in SAP Supplier Relationship Management (CVE-2025-42910, 9.0); administrators are urged to apply patches and mitigations immediately.

ToolShell SharePoint Vulnerabilities and Ongoing Exploitation

🔔 Unit 42 reports active exploitation of multiple on‑premises SharePoint vulnerabilities collectively dubbed ToolShell, enabling unauthenticated remote code execution, authentication bypass, and path traversal. Activity observed from mid‑July 2025 includes web shell deployment, theft of ASP.NET MachineKeys and ViewState material, and delivery of the 4L4MD4R ransomware in at least one chain. Organizations with internet‑exposed SharePoint servers should assume potential compromise and follow containment, patching, cryptographic rotation, and incident response guidance immediately.
