CVE-2022-24147Network attack vector

Service interruption via WAN-setting stack overflow

Published Feb 4, 2022 · Updated Aug 3, 2024

Stack overflow in Tenda AX3 firmware 16.03.12.10_CN allows remote attackers to interrupt service via crafted WAN settings. The fromAdvSetMacMtuWan function processes wanMTU, wanSpeed, cloneType, mac, and serviceName without enforcing stack-buffer bounds. The network path requires no authentication or user interaction, and the published impact is limited to availability.
