CVE-2026-6885Network attack vector

Unauthenticated code execution via web-shell upload

Published Apr 23, 2026 · Updated Apr 23, 2026

Arbitrary file upload in BorG SPM 2007 allows remote attackers to execute arbitrary code by uploading and invoking a web shell. TWCERT/CC identifies the affected behavior only as an unrestricted upload that accepts an executable web-shell file; no upload endpoint or validation failure has been published. No authentication or user interaction is required, and successful exploitation runs attacker-supplied code on the Windows-hosted server.
