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.
Multiple buffer overflow vulnerabilities in the web-based management interface of Cisco Small Business RV routers allow authenticated remote attackers to achieve root RCE or DoS.
Vulnerability
Multiple buffer overflow vulnerabilities exist in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers. The flaws are due to insufficient validation of user fields within incoming HTTP packets. Affected firmware versions have not been specified by Cisco; however all versions of the listed routers are presumed vulnerable until patched. The web-based management interface is accessible via LAN (cannot be disabled) or via WAN if remote management is enabled (disabled by default) [1].
Exploitation
An attacker must have valid Administrator credentials on the affected device. The attacker then sends a crafted HTTP request to the web-based management interface. The request contains malicious input in user fields that triggers a buffer overflow when processed by the device's firmware [1].
Impact
Successful exploitation allows the attacker to execute arbitrary commands with root-level privileges on the device, or to cause the device to restart unexpectedly, leading to a denial of service (DoS) condition. Full compromise of the router is possible under the RCE scenario [1].
Mitigation
Cisco has not released software updates that address these vulnerabilities, and there are no workarounds available. Users of affected devices should monitor Cisco's advisory for future fixes. As of the publication date (2022-07-21), these vulnerabilities are not listed in CISA's Known Exploited Vulnerabilities (KEV) catalog [1].
