CVE-2021-1158 Information

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 conduct cross-site scripting (XSS) attacks against a user of the interface. The vulnerabilities are due to insufficient input validation by 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 script code in the context of the affected interface or access sensitive browser-based information. To exploit these vulnerabilities an attacker would need to have valid administrator credentials on the affected device.
