CVE-2020-26838 — Sap Business Warehouse security vulnerability

Critical CVSS 9.1

SAP Business Warehouse, versions - 700, 701, 702, 731, 740, 750, 751, 752, 753, 754, 755, 782, and SAP BW4HANA, versions - 100, 200 allows an attacker authenticated with (high) developer privileges to submit a crafted request to generate and execute code without requiring any user interaction. It is possible to craft a request which will result in the execution of Operating System commands leading to Code Injection vulnerability which could completely compromise the confidentiality, integrity and availability of the server and any data or other applications running on it.

Matched remediation archetype

Command, code, expression, and template injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
