Cisco Small Business RV Series Routers Management Interface Command Injection Vulnerabilities

CVE-2021-1314

Description

Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV016, RV042, RV042G, RV082, RV320, and RV325 Routers could allow an authenticated, remote attacker to inject arbitrary commands that are executed with root privileges. These 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 a targeted device. A successful exploit could allow the attacker to execute arbitrary code as the root user on the underlying operating system. To exploit these vulnerabilities, an attacker would need to have valid administrator credentials on an affected device.

LLM-synthesized narrative grounded in this CVE's description and references.

Authenticated command injection in Cisco Small Business RV series routers allows root-level code execution via crafted HTTP requests.

Vulnerability

Multiple vulnerabilities exist in the web-based management interface of Cisco Small Business RV016, RV042, RV042G, RV082, RV320, and RV325 routers. The flaws are due to improper validation of user-supplied input in the web interface. An authenticated attacker can inject arbitrary commands that are executed with root privileges. All firmware versions prior to the fixed releases are affected [1].

Exploitation

An attacker must have valid administrator credentials on the targeted device. With these credentials, the attacker sends crafted HTTP requests to the web-based management interface. No additional user interaction is required. The attack is performed remotely over the network [1].

Impact

Successful exploitation allows the attacker to execute arbitrary commands as the root user on the underlying operating system. This results in full compromise of the device, including the ability to modify configuration, access sensitive data, and potentially pivot to other network segments [1].

Mitigation

Cisco has released free software updates that address these vulnerabilities. Customers should upgrade to the fixed firmware versions as specified in the Cisco Security Advisory [1]. No workarounds are available. The vulnerabilities are not listed on the CISA Known Exploited Vulnerabilities (KEV) catalog as of the publication date.
