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.

Authenticated remote code execution and DoS in Cisco Small Business RV routers due to insufficient input validation.
Vulnerability
Multiple vulnerabilities exist in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W routers (all versions without a patch) [1]. The issue stems from insufficient validation of user-supplied fields within incoming HTTP packets, allowing an authenticated attacker to send a crafted request that triggers a buffer overflow or other memory corruption [1].
Exploitation
To exploit these vulnerabilities, an attacker must have valid Administrator credentials on the affected device and be able to reach the web-based management interface via a LAN connection, or via WAN if remote management is enabled (disabled by default) [1]. The attacker sends a specially crafted HTTP request to the management interface; no additional user interaction is required [1].
Impact
A successful exploit can allow the attacker to execute arbitrary commands on the device with root-level privileges, leading to full compromise, or to cause the device to restart unexpectedly, resulting in a denial of service (DoS) condition [1].
Mitigation
As of the advisory date, Cisco has not released software updates that address these vulnerabilities, and there are no workarounds available [1]. Affected products have reached end-of-life status, and no fix is planned [1]. Users should consider migrating to a supported device.
