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.
A remote attacker with admin credentials can execute arbitrary commands or cause a DoS on multiple Cisco Small Business RV routers via insufficient HTTP input validation.
Vulnerability
Multiple vulnerabilities exist in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers [1]. These flaws are due to insufficient validation of user fields within incoming HTTP packets. The affected devices run firmware versions that have not been patched. The web management interface is accessible via LAN (cannot be disabled) or via WAN if remote management is enabled (disabled by default).
Exploitation
An attacker must have valid Administrator credentials on the affected device to exploit these vulnerabilities [1]. The exploitation steps are not detailed in the references, but the advisory states that an attacker can send a crafted HTTP request to the web-based management interface to trigger the vulnerability.
Impact
A successful exploit allows the attacker to execute arbitrary commands on the affected 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
Cisco has not released software updates that address these vulnerabilities, and there are no workarounds (no patch is available) [1]. These products are end-of-life, and Cisco has stated they will not release fixes. Users should consider migrating to a supported product.
