Detailsinfo

A vulnerability was found in Cisco RV016, RV042, RV082, RV320 and RV325 (Router Operating System). It has been classified as critical. This affects an unknown functionality 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. The summary by CVE is:

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 published 06/18/2020 as cisco-sa-rv-routers-Rj5JRfF8 as confirmed advisory (Website). The advisory is shared at tools.cisco.com. This vulnerability is uniquely identified as CVE-2020-3276 since 12/12/2019. It is possible to initiate the attack remotely. The successful exploitation needs a authentication. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1202 for this issue.

Upgrading eliminates this vulnerability.
