Detailsinfo

A vulnerability was found in Cisco RV130 and RV110W (affected version not known). It has been declared as very critical. This vulnerability affects the function sub_34984 of the component IPv6 Configuration Handler. The manipulation of the argument lan_ipv6_prefixlen with an unknown input leads to a os command injection vulnerability. The CWE definition for the vulnerability is CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

An OS command injection vulnerability exists in the sub_34984() function of the "rc" binary in Cisco RV130/RV130W with firmware 1.0.3.55 and RV110W routers with firmware 1.2.2.5 / 1.2.2.8. The lan_ipv6_prefixlen configuration parameter is not properly sanitized, which could allow an authenticated remote attacker to execute arbitrary OS commands with root privileges.

The advisory is available at github.com. This vulnerability was named CVE-2026-24699 since 01/23/2026. The exploitation appears to be easy. The attack can be initiated remotely.
