CVE-2024-34687 — Sap Sap Basis security vulnerability

Critical CVSS 9

SAP NetWeaver Application Server for ABAP and ABAP Platform do not sufficiently encode user controlled inputs, resulting in Cross-Site Scripting (XSS) vulnerability. An attacker can control code that is executed within a user’s browser, which could result in modification, deletion of data, including accessing or deleting files, or stealing session cookies which an attacker could use to hijack a user’s session. Hence, this could have impact on Confidentiality, Integrity and Availability of the system.

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.
