## Technical details

An OS command injection vulnerability exists in the 'rc' binary of Cisco RV110W, RV130, and RV130W routers. The root cause is the start_bonjour() function, which retrieves the 'wan_hostname' configuration parameter via nvram_get() and concatenates it into a system command string ('bonjour -N %s') without proper sanitization or escaping. This string is subsequently executed using the system() function. An authenticated remote attacker can exploit this by setting a malicious 'wan_hostname' containing shell metacharacters, leading to arbitrary code execution with root privileges. This affects firmware versions 1.0.3.55 for RV130/RV130W and 1.2.2.5/1.2.2.8 for RV110W.

## Affected products

- Cisco RV130 VPN Firewall 1.0.3.55
- Cisco RV130W Wireless-N VPN Firewall 1.0.3.55
