CVE-2024-22942Public exploitNetwork attack vector

Unauthenticated command execution via unsanitized hostName

Published Jan 11, 2024 · Updated Jun 3, 2025

OS command injection in TOTOLINK A3300R firmware 17.0.0cu.557_B20221024 allows remote attackers to execute arbitrary commands via hostName. The setWanCfg handler reads hostName from the request body and passes it without neutralization to doSystem, which invokes an operating-system command. Network access is sufficient without authentication or user interaction, and the published proof writes command output into the device's web root.
