CVE-2026-24699Public exploitNetwork attack vector

Authenticated root command execution via unsanitized prefix length

Published Jul 8, 2026 · Updated Jul 8, 2026

OS command injection in Cisco RV130/RV130W 1.0.3.55 and RV110W 1.2.2.5 and 1.2.2.8 allows remote authenticated users to run root commands. The rc binary's sub_34984() function reads lan_ipv6_prefixlen from NVRAM, interpolates it with sprintf into an ifconfig command, and passes the result to system() without sanitizing shell metacharacters. Exploitation requires configuration access and lan_ip_mode to be absent or not equal to 1; injected commands run as root and can persist across network reinitialization.
