CVE-2022-28217 — Sap Netweaver security vulnerability

Medium CVSS 6.5

Some part of SAP NetWeaver (EP Web Page Composer) does not sufficiently validate an XML document accepted from an untrusted source, which allows an adversary to exploit unprotected XML parking at endpoints, and a possibility to conduct SSRF attacks that could compromise system�s Availability by causing system to crash.

Matched remediation archetype

Server-side request forgery and unintended proxying

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

Check exposure

  • Inventory server-side URL fetchers, webhooks, importers, previews, redirects, proxies, and protocol handlers reachable from untrusted input.
  • Map egress paths to internal services, metadata endpoints, loopback, private address space, and privileged control planes.
  • Review DNS resolution, redirect, proxy, credential-forwarding, and URL parsing behavior without requesting sensitive targets.

Remediate safely

  • Replace arbitrary destinations with named integrations or a strict allowlist of schemes, hosts, ports, and paths.
  • Resolve and validate every destination and redirect hop, then enforce egress policy independently of application checks.
  • Remove ambient credentials and sensitive headers from fetchers; apply response size, time, and content limits.
