Detailsinfo

A vulnerability was found in Cisco RV016, RV042, RV082, RV320 and RV325 (Router Operating System). It has been declared as critical. This vulnerability affects some unknown functionality of the component Web-based Management Interface. The manipulation as part of a Request leads to a command injection vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect 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 released 06/18/2020 as cisco-sa-rv-routers-Rj5JRfF8 as confirmed advisory (Website). The advisory is available at tools.cisco.com. This vulnerability was named CVE-2020-3277 since 12/12/2019. The attack can be initiated remotely. A single authentication is required for exploitation. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1202 by the MITRE ATT&CK project.
