CVE-2021-46229Known exploitationNetwork attack vector

Arbitrary command execution via unsanitized name parameter

Published Feb 4, 2022 · Updated Aug 4, 2024

Command injection in D-Link DI-7200GV2 E1 firmware 21.04.09E1 and earlier allows remote attackers to execute arbitrary commands. The usb_paswd.asp handler incorporates the attacker-controlled name parameter into an executed command without neutralizing command syntax. The management interface must be reachable from the LAN, and successful exploitation permits commands that can read, alter, or interrupt device functions.
