A vulnerability has been found in Cisco RV016, RV042, RV082, RV320 and RV325 (Router Operating System) and classified as critical. This vulnerability affects an unknown functionality of the component Web-based Management Interface. The manipulation as part of a Request leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. 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 code on an affected device. The vulnerabilities are due to insufficient boundary restrictions on user-supplied input to scripts in the web-based management interface. An attacker with administrative privileges that are sufficient to log in to the web-based management interface could exploit each vulnerability by sending crafted requests that contain overly large values to an affected device, causing a stack overflow. A successful exploit could allow the attacker to cause the device to crash or allow the attacker to execute arbitrary code with root privileges on the underlying operating system.

The weakness was disclosed 06/18/2020 as cisco-sa-rv-routers-stack-vUxH as confirmed advisory (Website). The advisory is shared for download at tools.cisco.com. This vulnerability was named CVE-2020-3289 since 12/12/2019. The attack can be initiated remotely. The successful exploitation needs a single authentication. There are neither technical details nor an exploit publicly available.

Upgrading eliminates this vulnerability.

The entries 156889, 156890, 156891 and 156893 are pretty similar.
