CVE-2020-26826
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 · uneditedProcess Integration Monitoring of SAP NetWeaver AS JAVA, versions - 7.31, 7.40, 7.50, allows an attacker to upload any file (including script files) without proper file format validation, leading to Unrestricted File Upload.
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 · moderate confidenceUnrestricted file upload vulnerability in SAP NetWeaver AS JAVA Process Integration Monitoring component allows attackers to upload arbitrary files including script files due to lack of proper file format validation. Successful exploitation could lead to remote code execution if uploaded scripts are placed in web-accessible directories.

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.
-
Identify SAP NetWeaver AS Java versionCheck the installed SAP NetWeaver AS Java version via SAP MII transaction, SAP MMC, or by inspecting the SAP system information (transaction SM51 or SAP LMF). Compare against affected versions 7.31, 7.40, and 7.50.Affected if The installed version matches exactly 7.31, 7.40, or 7.50.
-
Verify Process Integration Monitoring component is presentConfirm the Process Integration Monitoring (PIMon) component is installed and running on the SAP NetWeaver AS Java system. Check via SAP transaction SXMB_MONITOR or component listing in SAP System Landscape Directory.Affected if The Process Integration Monitoring component exists in the environment.
-
Locate file upload functionality in PIMonIdentify if the Process Integration Monitoring component exposes any file upload endpoints or interfaces. Inspect web services or HTTP handlers related to PIMon component in the SAP NetWeaver AS Java web container.Affected if File upload capability exists within the Process Integration Monitoring component.
-
Inspect upload directory configurationsReview the web application configuration files for the PIMon component to identify upload directories. Check if these directories are mapped under the web root (e.g., in the /webdynpro/ or similar paths).Affected if Upload directories are web-accessible or mapped under the SAP web context root.
-
Check script execution restrictionsExamine the configuration of upload directories and the SAP NetWeaver AS Java web container to determine if script execution is restricted or disabled in these paths.Affected if Script execution is not explicitly disabled in upload directories, or script file extensions are accepted without validation.
The environment is affected if SAP NetWeaver AS Java versions 7.31, 7.40, or 7.50 are running with the Process Integration Monitoring component enabled and its upload directories are web-accessible without script execution restrictions.

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 when available. Implement strict file format validation and disable script execution in upload directories within the Process Integration Monitoring component.
