CVE-2022-4616Network attack vector

Unauthenticated file manipulation via diagnosis-page command injection

Published Jan 12, 2023 · Updated Jan 16, 2025

Command injection in Delta Electronics, Inc. 4G Router DX-3021 before 1.24 allows remote attackers to manipulate files via network diagnostics. The network diagnosis page fails to neutralize attacker-controlled diagnostic input before using it in a command; public records do not identify the parameter or handler. Unauthenticated network access is sufficient to add or delete files and change permissions, affecting integrity and availability.
