CVE-2020-3290Cisco Small Business RV Series Routers Stack Overflow Arbitrary Code Execution Vulnerabilities
High 7.2
In plain English
A high-severity memory corruption in Cisco Small Business RV Series Router Firmware from Cisco. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 3.2% (higher than 88% of all known vulnerabilities).
Official description
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.
