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.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Cisco Small Business RV series routers contain multiple vulnerabilities in the web-based management interface allowing authenticated remote attackers to execute arbitrary code or cause a denial of service.
Vulnerability
Cisco Small Business RV110W, RV130, RV130W, and RV215W routers contain multiple vulnerabilities in the web-based management interface due to insufficient validation of user fields within incoming HTTP packets [1]. These issues affect all firmware versions of the listed devices. The web-based management interface is accessible via a LAN connection (cannot be disabled) or via WAN if remote management is enabled (disabled by default).
Exploitation
An attacker must have valid Administrator credentials for the device [1]. With those credentials, the attacker sends a crafted HTTP request to the web-based management interface, exploiting the insufficient validation to trigger arbitrary command execution or a device restart.
Impact
Successful exploitation allows an authenticated remote attacker to execute arbitrary commands on an affected device with root-level privileges, or to 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 there are no workarounds available [1]. These devices are end-of-life; no patches are expected.
