TITLE

Cisco Small Business RV Unreliable Data Deserialization Vulnerability in Series Router

Trust: 0.8

sources: JVNDB: JVNDB-2019-012823

DESCRIPTION

A vulnerability in the web-based management interface of certain Cisco Small Business RV Series Routers could allow an authenticated, remote attacker to execute arbitrary commands with root privileges. The attacker must have either a valid credential or an active session token. The vulnerability is due to lack of input validation of the HTTP payload. An attacker could exploit this vulnerability by sending a malicious HTTP request to the web-based management interface of the targeted device. A successful exploit could allow the attacker to execute commands with root privileges. Cisco Small Business RV A series router contains an unreliable data deserialization vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. The Cisco RV016 Multi-WAN VPN Router is a VPN (Virtual Private Network) router from Cisco (Cisco)
