CVE-2025-29062Network attack vector

Unauthenticated code execution via unsanitized time parameters

Published Apr 2, 2025 · Updated Apr 3, 2025

Command injection in LB-Link BL-AC2100 firmware 1.0.4 and earlier allows remote attackers to execute arbitrary code via HTTP requests. The set_LimitClient_cfg handler in the GoAhead web service incorporates the time1 and time2 parameters into a command without neutralizing command syntax. No authentication or user interaction is required, and successful injection executes attacker-chosen commands with the web service's privileges.
