Name of the Vulnerable Software and Affected Versions: Cisco RV110W versions not specified Cisco RV130 versions not specified Cisco RV130W versions not specified Cisco RV215W versions not specified

Description: The issue is related to insufficient protection of the web page structure in the web-based management interface of the affected routers. This could allow a remote attacker to conduct cross-site scripting (XSS) attacks. 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, potentially allowing the execution of arbitrary script code in the context of the affected interface or access to sensitive browser-based information.

Recommendations: For Cisco RV110W, update to a version that addresses the insufficient input validation issue. For Cisco RV130, update to a version that addresses the insufficient input validation issue. For Cisco RV130W, update to a version that addresses the insufficient input validation issue. For Cisco RV215W, update to a version that addresses the insufficient input validation issue. As a temporary workaround, consider restricting access to the web-based management interface to minimize the risk of exploitation.
