TITLE

TOTOLINK T10 comment parameter buffer overflow vulnerability

Trust: 0.6

sources: CNVD: CNVD-2023-64048

DESCRIPTION

TOTOLINK T10_v2 5.9c.5061_B20200511 has a stack-based buffer overflow in setStaticDhcpConfig in /lib/cste_modules/lan.so. Attackers can send crafted data in an MQTT packet, via the comment parameter, to control the return address and execute code. TOTOLINK T10 is a wireless network system router produced by China Zeon Electronics (TOTOLINK). The vulnerability originates from the fact that the comment parameter in setStaticDhcpConfig of /lib/cste_modules/lan.so fails to correctly verify the length of the input data. Remote attackers can exploit this vulnerability in the system execute arbitrary code or cause a denial of service attack
