Trust: 0.8

sources: JVNDB: JVNDB-2021-002581

DESCRIPTION

Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers could allow an authenticated, remote attacker to execute arbitrary code or cause an affected device to restart unexpectedly. The 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 an affected device. A successful exploit could allow the attacker to execute arbitrary code as the root user on the underlying operating system or cause the device to reload, resulting in a denial of service (DoS) condition. To exploit these vulnerabilities, an attacker would need to have valid administrator credentials on the affected device. Cisco has not released software updates that address these vulnerabilities. plural Cisco Small Business RV Routers are vulnerable to out-of-bounds writesInformation is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. Cisco RV110W is a Wireless-N VPN firewall, Cisco RV130 is a multifunctional VPN router, Cisco RV130W is a Wireless-N multifunctional VPN router, and Cisco RV215W is a Wireless-N VPN router. Or cause the device to reload. Cisco RV110W, etc. The vulnerability exists in the following devices or models: Cisco Small Business RV110W, Cisco Small Business RV130, Cisco Small Business RV130W, Cisco Small Business RV215W
