CVE-2018-2363
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSAP NetWeaver, SAP BASIS from 7.00 to 7.02, from 7.10 to 7.11, 7.30, 7.31, 7.40, from 7.50 to 7.52, contains code that allows you to execute arbitrary program code of the user's choice. A malicious user can therefore control the behaviour of the system or can potentially escalate privileges by executing malicious code without legitimate credentials.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThis is an authenticated remote code execution vulnerability in SAP NetWeaver and SAP BASIS. The vulnerability allows a malicious user to execute arbitrary program code of their choice, potentially gaining full control of the system or escalating privileges without legitimate credentials.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm SAP NetWeaver installationIdentify whether SAP NetWeaver or SAP BASIS is installed on the system by checking for SAP-related processes, services, or installed components using system inventory tools or by reviewing SAP management interfaces.Affected if SAP NetWeaver or SAP BASIS is present on the system
-
Identify the SAP NetWeaver versionDetermine the exact version of SAP NetWeaver installed by querying the SAP system via transaction code SM51, using SAP MMC, or checking SAP installation logs and system information.Affected if The installed version matches any of these ranges: 7.00 through 7.02, 7.10 through 7.11, 7.30, 7.31, 7.40, or 7.50 through 7.52, or if it is any version of SAP NetWeaver (all versions affected)
-
Verify if remote authentication is enabledCheck SAP system configuration for enabled remote authentication methods (RFC, SAP Gateway, or HTTP services exposed to network) by reviewing SAP profile parameters and security settings in transaction code SU01 or SM37.Affected if Remote authentication or RFC access is enabled and exposed to network (required condition for authenticated RCE)
-
Review user account securityExamine SAP user accounts for any unauthorized or unexpected privileged accounts, and check audit logs (transaction code SM20 or RSAU_READ_LOG) for authentication attempts from unfamiliar sources.Affected if Unknown privileged accounts exist or suspicious authentication activity is found in logs
A user is affected if SAP NetWeaver of any version or SAP Business Application Software Integrated Solution within the listed version ranges is installed with remote authentication enabled, as this allows the authenticated RCE to be exploited.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply SAP security patches for CVE-2018-2363 immediately. Until patches are applied, restrict network access to SAP NetWeaver systems to trusted sources only and monitor for suspicious activity.
