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

CVE-2021-1186

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 code or cause DoS on Cisco RV110W, RV130, RV130W, RV215W routers via crafted HTTP requests due to improper input validation. No fix available.

Vulnerability

The vulnerability exists in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W routers. It is due to improper validation of user-supplied input in the web-based management interface. An authenticated remote attacker with valid administrator credentials can send crafted HTTP requests to trigger the issue. All firmware versions are affected, and Cisco has not released any software updates.

Exploitation

An attacker must have valid administrator credentials to access the web-based management interface. The attacker then sends specially crafted HTTP requests to the affected device. No user interaction is required beyond the initial authentication. The management interface is accessible via LAN, or via WAN if remote management is enabled (disabled by default).

Impact

Successful exploitation allows 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 condition. This grants full control over the device or disrupts its availability.

Mitigation

Cisco has not released software updates to address these vulnerabilities [1]. There are no workarounds available. Affected products are end-of-life? The advisory does not state EOL, but no fixes are coming. Users should consider migrating to supported devices if possible. These vulnerabilities are not on the CISA KEV list as of the publication date.
