CVE-2020-3288

TITLE

plural Cisco Small Business RV Buffer error vulnerability in series routers

Trust: 0.8

sources: JVNDB: JVNDB-2020-006862

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. plural Cisco Small Business RV A buffer error vulnerability exists in series routers.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. Cisco Small Business RV016 Multi-WAN VPN is a VPN router from Cisco in the United States. The vulnerability stems from the program's failure to properly limit the user's input boundary
