Cisco Small Business RV160, RV160W, RV260, RV260P, and RV260W VPN Routers Remote Code Execution Vulnerabilities
Description
Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV160, RV160W, RV260, RV260P, and RV260W VPN Routers could allow an unauthenticated, remote attacker to execute arbitrary code as the root user on an affected device. These vulnerabilities exist because HTTP requests are not properly validated. An attacker could exploit these vulnerabilities by sending a crafted HTTP request to the web-based management interface of an affected device. A successful exploit could allow the attacker to remotely execute arbitrary code on the device.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Multiple unauthenticated remote code execution vulnerabilities in Cisco Small Business RV160, RV260 series VPN routers allow arbitrary code execution as root via crafted HTTP requests.
Vulnerability
The vulnerabilities reside in the web-based management interface of Cisco Small Business RV160 (RV160, RV160W), RV260 (RV260, RV260P, RV260W) VPN Routers. The root cause is improper validation of HTTP requests, allowing an unauthenticated, remote attacker to trigger arbitrary code execution. All firmware versions prior to the fixed releases are affected [1].
Exploitation
An attacker does not require authentication or prior access to the device. The exploitation vector is sending a specially crafted HTTP request to the web-based management interface of an affected router. No user interaction is needed [1].
Impact
Successful exploitation grants the attacker arbitrary code execution as the root user, resulting in complete compromise of the device's confidentiality, integrity, and availability. The attacker gains full administrative control [1].
Mitigation
Cisco has released free software updates to address these vulnerabilities. The fixed firmware versions are detailed in the Cisco Security Advisory [1]. Customers should upgrade to the latest available firmware. No workarounds are available; the only mitigation is applying the patch [1].
