Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers Remote Command Execution and Denial of Service Vulnerabilities
Description
Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers could allow an authenticated, remote attacker to execute arbitrary code on an affected device or cause the device to restart unexpectedly, resulting in a denial of service (DoS) condition. These vulnerabilities are due to insufficient validation of user fields within incoming HTTP packets. An attacker could exploit these vulnerabilities by sending a crafted request to the web-based management interface. A successful exploit could allow the attacker to execute arbitrary commands on an affected device with root-level privileges or to cause the device to restart unexpectedly, resulting in a DoS condition. To exploit these vulnerabilities, an attacker would need to have valid Administrator credentials on the affected device. Cisco has not released software updates that address these vulnerabilities.

Multiple vulnerabilities in Cisco Small Business RV series routers allow authenticated remote code execution or DoS due to insufficient input validation; no patch available.
Vulnerability
Multiple vulnerabilities exist in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers [1]. These vulnerabilities are due to insufficient validation of user fields within incoming HTTP packets. An attacker with valid Administrator credentials can send a crafted request to exploit this flaw.
Exploitation
To exploit, an attacker must have valid Administrator credentials for the affected device. The attacker then sends a specially crafted HTTP request to the web-based management interface. The interface is accessible via LAN connection (cannot be disabled) or WAN if remote management is enabled (disabled by default) [1].
Impact
Successful exploitation allows an attacker to execute arbitrary commands on the device with root-level privileges or cause the device to restart unexpectedly, resulting in a denial of service (DoS) condition [1].
Mitigation
Cisco has not released software updates that address these vulnerabilities, and no workarounds exist [1]. Users should consider restricting access to the management interface and disabling remote management if not required.
