title: Potential CVE-2022-21587 Arbitrary File Upload Attempts via Oracle EBS Web Services
id: d8e9cf84-4a9a-4fe3-b270-7f00c7fba9c2
status: test
description: This rule flags HTTP POST requests whose URI query contains Oracle E-Business Suite (EBS) Bne* service endpoints with uueupload=TRUE. Such requests are consistent with attempted exploitation of CVE-2022-21587, an arbitrary file upload vulnerability that can enable unauthenticated remote code execution. It relies on webserver HTTP request telemetry capturing method and full query-string content, matching the specific OA_HTML/Bne* endpoints and parameter value.
