Authenticated path traversal via downloadas cmd argument
Published Sep 22, 2025 · Updated Sep 22, 2025
Path traversal in /downloadas/ in JSC R7 R7-Office Document Server 20250820 allows remote authenticated users to escape an intended path via cmd. The handler processes attacker-controlled traversal elements in cmd without adequate pathname restriction; its function and code-level operation are undisclosed. Vendor testing consistently returned proper errors, so public evidence demonstrates no successful file read, write, deletion, or service interruption.
