CVE-2021-38484Network attack vector

Administrator code execution via unchecked file upload

Published Oct 19, 2021 · Updated Sep 16, 2024

Unrestricted file upload in InHand Networks InRouter615-S 2.3.0.r4724 and 2.3.0.r4870 allows remote authenticated users to execute code. The management portal accepts administrator-supplied files without checking their type or signature before storing them on the device. Administrator access is required; a crafted upload can execute code, inject script into portal content, or delete system files.
