Cisco RV016/RV042/RV082/RV320/RV325 Web-based Management Interface Request command injection

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability classified as critical has been found in Cisco RV016, RV042, RV082, RV320 and RV325 (Router Operating System). Affected is an unknown code of the component Web-based Management Interface. The manipulation as part of a Request leads to a command injection vulnerability. CWE is classifying the issue as CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV320 and RV325 Series Routers and Cisco Small Business RV016, RV042, and RV082 Routers could allow an authenticated, remote attacker with administrative privileges to execute arbitrary commands on an affected device. The vulnerabilities exist because the web-based management interface does not properly validate user-supplied input to scripts. An attacker with administrative privileges that are sufficient to log in to the web-based management interface could exploit each vulnerability by sending malicious requests to an affected device. A successful exploit could allow the attacker to execute arbitrary commands with root privileges on the underlying operating system.

The weakness was presented 06/18/2020 as cisco-sa-rv-routers-Rj5JRfF8 as confirmed advisory (Website). The advisory is shared for download at tools.cisco.com. This vulnerability is traded as CVE-2020-3279 since 12/12/2019. It is possible to launch the attack remotely. A authentication is needed for exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1202.

Upgrading eliminates this vulnerability.
