CVE-2026-2068Public exploitNetwork attack vector

Authenticated crash via unchecked ServerIp copy

Published Feb 6, 2026 · Updated Feb 6, 2026

Buffer overflow in the UTT 进取 520W 1.7.7-180627 syslog handler allows remote authenticated users to crash the router. When SyslogEnable is on, /goform/formSyslogConf passes the attacker-controlled ServerIp value to strcpy without enforcing the destination buffer's size. Access requires a valid administrative Digest session, and the published proof of concept establishes a denial-of-service outcome rather than code execution.
