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.

Blue-Team Playbook Snippets

# WAF quick filter idea (pseudocode)
Block if URI matches /(sap\/public|sap\/bc|sap\/opu\/odata)/ and method in (POST,PUT) and content-length > 1MB

# Linux quick sweep for webshell-y files near SAP HTTP dirs
find /usr/sap -type f -regex '.*\.\(jsp\|js\|php\|sh\)' -mmin -120 -ls

# Windows: hunt for new files in SAP dir tree (PowerShell)
Get-ChildItem -Recurse "C:\usr\sap" -Include *.jsp,*.js,*.php,*.cmd,*.ps1 |
 Where-Object { $_.LastWriteTime -gt (Get-Date).AddHours(-2) } | Select FullName,LastWriteTime

Executive Communications (Template)

“We’ve removed direct exposure, applied SAP’s fixes, rotated keys, and deployed enhanced monitoring. No customer data loss confirmed at this time; we will update stakeholders within 24 hours.”
