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

CVE-2021-1191

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.

Authenticated remote command execution and DoS vulnerabilities in Cisco Small Business RV series routers due to improper input validation; no fix available.

Vulnerability

Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W routers allow authenticated remote attackers to execute arbitrary code or cause device reload. The issues stem from improper validation of user-supplied input in the web-based management interface. Affected versions include all firmware releases for these models, as no patches exist. [1]

Exploitation

An attacker must have valid administrator credentials for the affected device. The attacker can then send crafted HTTP requests to the web-based management interface. This interface is accessible via LAN and optionally via WAN if remote management is enabled. No user interaction is required beyond authentication. [1]

Impact

Successful exploitation allows the attacker to execute arbitrary code with root privileges on the underlying operating system, leading to full compromise of the device. Alternatively, the attacker can trigger a device reload, causing a denial of service condition. [1]

Mitigation

Cisco has not released software updates to address these vulnerabilities. No workarounds exist. Users are advised to disable remote management and restrict access to the management interface to trusted networks. The vulnerabilities are not listed in CISA's Known Exploited Vulnerabilities catalog. [1]
