CVE-2021-37608Public exploitNetwork attack vector

Remote command execution via wrong upload validation

Published Aug 18, 2021 · Updated Aug 4, 2024

Unrestricted file upload in Apache OFBiz 17.12.07 and earlier allows remote attackers to execute commands through Image Management. The addMultipleuploadForProduct service writes an uploaded image to disk but passes a different fileToCheck path to SecuredUpload.isValidFile, leaving the written file unvalidated. No authentication or user interaction is required, and accepted executable content runs with the OFBiz service's privileges.
