TITLE

plural Cisco Small Business RV Command injection vulnerability in router

Trust: 0.8

sources: JVNDB: JVNDB-2021-003109

DESCRIPTION

Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV016, RV042, RV042G, RV082, RV320, and RV325 Routers could allow an authenticated, remote attacker to inject arbitrary commands that are executed with root privileges. These vulnerabilities are due to improper validation of user-supplied input in the web-based management interface. An attacker could exploit these vulnerabilities by sending crafted HTTP requests to a targeted device. A successful exploit could allow the attacker to execute arbitrary code as the root user on the underlying operating system. To exploit these vulnerabilities, an attacker would need to have valid administrator credentials on an affected device. plural Cisco Small Business RV A command injection vulnerability exists in the router.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state
