Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers Management Interface Remote Command Execution and Denial of Service Vulnerabilities

CVE-2021-1204

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 or cause an affected device to restart unexpectedly. The vulnerabilities are due to improper validation of user-supplied input in the web-based management interface. An attacker could exploit these vulnerabilities by sending crafted HTTP requests to an affected device. A successful exploit could allow the attacker to execute arbitrary code as the root user on the underlying operating system or cause the device to reload, resulting in a denial of service (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.

Authenticated remote attackers can execute arbitrary code or cause DoS on Cisco Small Business RV110W, RV130, RV130W, and RV215W routers via crafted HTTP requests due to improper input validation.

Vulnerability

The vulnerability resides in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W routers [1]. Due to improper validation of user-supplied input, an authenticated remote attacker can send crafted HTTP requests to trigger arbitrary code execution or denial of service. All firmware versions prior to any fix are affected; Cisco has not released software updates.

Exploitation

An attacker must have valid administrator credentials for the device. The attacker sends specially crafted HTTP requests to the web-based management interface over a local LAN connection (which cannot be disabled) or over the WAN if remote management is enabled (disabled by default) [1]. No user interaction is required.

Impact

Successful exploitation allows the attacker to execute arbitrary code with root privileges on the underlying operating system or cause the device to reload, resulting in a denial of service condition [1].

Mitigation

Cisco has not released software updates that address these vulnerabilities [1]. No workarounds are available. The devices remain vulnerable as of the publication date. These CVEs are not listed in the Known Exploited Vulnerabilities catalog.
