CVE-2021-27600 — Sap Manufacturing Execution security vulnerability

Medium CVSS 6.4

SAP Manufacturing Execution (System Rules), versions - 15.1, 15.2, 15.3, 15.4, allows an authorized attacker to embed malicious code into HTTP parameter and send it to the server because SAP Manufacturing Execution (System Rules) tab does not sufficiently encode some parameters, resulting in Stored Cross-Site Scripting (XSS) vulnerability. The malicious code can be used for different purposes. e.g., information can be read, modified, and sent to the attacker. However, availability of the server cannot be impacted.

Matched remediation archetype

Cross-site scripting and unsafe browser output

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

Check exposure

  • Trace reflected, stored, and DOM-derived untrusted values into HTML, attributes, URLs, styles, scripts, and client-side template sinks.
  • Identify affected origins, authenticated user roles, sensitive browser capabilities, and where content is shared across tenants.
  • Review framework escaping, rich-text sanitization, legacy templates, and client-side rendering paths.

Remediate safely

  • Use context-aware framework output encoding and safe DOM APIs; keep untrusted data out of executable contexts.
  • Sanitize intentionally supported markup with a maintained allowlist policy and validate URLs and attributes separately.
  • Update affected rendering components and add tests for every output context using inert sentinel markup.
