Cisco Security Advisory: Cisco RV220 Management Authentication Bypass Vulnerability
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cisco RV220W Management Authentication Bypass Vulnerability Advisory ID: cisco-sa-20160127-rv220 Revision 1.0 For Public Release 2016 January 27 16:00 UTC (GMT) +--------------------------------------------------------------------- Summary ======= A vulnerability in the web-based management interface of Cisco RV220W Wireless Network Security Firewall devices could allow an unauthenticated, remote attacker to bypass authentication and gain administrative privileges on a targeted device. The vulnerability is due to insufficient input validation of HTTP request headers that are sent to the web-based management interface of an affected device. An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted HTTP request that contains malicious SQL statements to the management interface of a targeted device. Depending on whether remote management is configured for the device, the management interface may use the SQL code in the HTTP request header to determine user privileges for the device. A successful exploit could allow the attacker to bypass authentication on the management interface and gain administrative privileges on the device. Cisco released a firmware update that addresses this vulnerability. There are workarounds that mitigate this vulnerability.
