CVE-2022-35294Network attack vector

Authentication theft via stored file script execution

Published Sep 13, 2022 · Updated Aug 3, 2024

Stored XSS in SAP NetWeaver AS ABAP affected releases allows remote authenticated users to steal authentication data through a crafted file. The file upload path stores attacker-controlled active content without neutralizing it before another business user downloads and opens the file. Basic business-user privileges are required to upload the file, and a second user must download and view it before script execution can expose authentication data and enable impersonation.
