Note: Insert the exact CVE, SAP component (e.g., NetWeaver AS ABAP/Java, Web Dispatcher, ICM), and HotNews note once confirmed. This guide covers the typical unauthenticated/RCE/priv-esc kill chains seen in SAP internet-facing or partner-connected systems.
TL;DR (Exec Risk)
- What: A critical SAP vulnerability enables code execution and/or admin takeover potentially without valid credentials.
- Impact: ERP downtime, corrupted ledgers, theft of pricing/IP, vendor fraud, payroll diversion, and supply-chain stoppage.
- Action: Patch immediately, pull internet exposure behind WAF/VPN, and enforce emergency monitoring of SAP logs & connectors.
Who Is Exposed
- Internet-facing SAP endpoints (Web Dispatcher/ICM/HTTP/SOAP/REST) and any DMZ reverse proxies to SAP.
- Unsegmented internal landscapes where app and DB tiers share flat networks.
- High-priv integration users (RFC, CPI, PI/PO, SolMan, BW, S/4HANA) reused across systems.
Immediate Triage (First 2–6 Hours)
- Freeze change windows except emergency patching; snapshot/backup critical app servers.
- Perimeter: remove direct internet exposure where feasible; force access via VPN/ZTNA; enable WAF rules for suspicious SAP URIs.
- Accounts: rotate technical/RFC users; disable unused high-priv roles; enforce SSO/MFA on admin portals.
- Threat hunt for webshells, odd SM21, ST22 dumps, and unexpected SM19/SM20 audit entries.
Patch & Mitigation
- Apply SAP Security Note: {{SAP_NOTE_ID}} / CVE-{{CVE_ID}} to all affected components and dependent stacks.
- Web Dispatcher / ICM hardening: disable unused methods, enforce TLS modern ciphers, restrict admin ports, rate-limit uploads.
- Segmentation: isolate app, CI/CD (ChaRM/CTS+), and DB; firewall RFC/ICF to only approved peers.
- Rotate secrets: SECSTORE, STRUST, integration keys (CPI, PI/PO), and partner credentials.
Detection Ideas (High-Signal)
- Web access: unusual POSTs to
/sap/public/
,/sap/bc/
,/sap/opu/odata/
, or large multipart uploads. - Process creation on app hosts: shells, scripting engines, or unfamiliar child processes under
sapstartsrv
/disp+work
. - Audit: new SAP_ALL/SAP_NEW grants; role/profile changes outside CAB windows.
- Lateral: Kerberos/RFC storms from a single jump host; odd connections to HANA/DB ports.
