Description Preview
Multiple vulnerabilities exist in the web-based management interface of Cisco Small Business RV016, RV042, RV042G, RV082, RV320, and RV325 Routers. These vulnerabilities stem from improper validation of user-supplied input in the management interface. An authenticated remote attacker with valid administrator credentials could exploit these vulnerabilities by sending crafted HTTP requests to an affected device. Successful exploitation could allow the attacker to execute arbitrary code with root privileges on the underlying operating system or cause the device to reload, resulting in a denial of service (DoS) condition.
Overview
The affected Cisco Small Business RV Series Routers contain critical vulnerabilities in their web-based management interfaces that could be exploited by authenticated attackers. The vulnerabilities are caused by insufficient input validation mechanisms, allowing specially crafted HTTP requests to trigger arbitrary code execution or device reboots. These vulnerabilities are particularly severe as successful exploitation provides root-level access to the device's operating system. Although authentication is required to exploit these vulnerabilities, administrators should consider this a high-risk issue requiring immediate attention, as compromised administrator credentials would give attackers complete control over the affected devices.
Remediation
To address these vulnerabilities, administrators should:
- Apply the latest firmware updates provided by Cisco for the affected devices as soon as possible.
- Implement strong password policies for administrator accounts to reduce the risk of credential compromise.
- Limit management interface access to trusted networks only.
- Consider implementing network segmentation to isolate the management interfaces from untrusted networks.
- Monitor for suspicious activities or unauthorized access attempts to the management interface.
- If patching is not immediately possible, consider temporarily disabling remote management functionality until updates can be applied.
