CVE-2021-37131Network attack vector

Command execution via unneutralized CSV fields

Published Oct 27, 2021 · Updated Aug 4, 2024

CSV injection in Huawei ManageOne, iManager NetEco, and iManager NetEco 6000 allows remote authenticated users to create malicious CSV files. The products place insufficiently validated parameters into CSV fields that spreadsheet software can interpret as formulas or commands. High-privilege device access and user interaction with the generated file are required; opening it can expose data or execute commands.
