TITLE

Linksys BEFSX41 EtherFast Router Log View Remote Denial of Service Vulnerability

Trust: 1.2

sources: CNVD: CNVD-2003-3132 // CNNVD: CNNVD-200312-245

DESCRIPTION

Buffer overflow in the system log viewer of Linksys BEFSX41 1.44.3 allows remote attackers to cause a denial of service via an HTTP request with a long Log_Page_Num variable. Linksys BEFSX41 is a broadband router that includes a web-based management interface. Linksys BEFSX41 lacks sufficient filtering when processing user-submitted input. Remote attackers can use this vulnerability to conduct denial-of-service attacks on routers. Linksys BEFSX41 general default address (http://192.168.1.1) contains a WEB-based management interface, which can be accessed using "get" mode. Due to lack of sufficient filtering of the "Log_Page_Num" parameter, when a long string is sent to the system log Viewer "Log_Page_Num" parameter can cause router to crash. Linksys BEFSX41 EtherFast Routers are prone to a denial of service. This issue is exposed via the log viewer in the web administrative interface. By submitting an invalid value for the "Log_Page_Num" parameter, it is possible to trigger this condition, causing the router to be unresponsive. While exploitation does require a logged in administrative user to submit a request to the log viewer with malformed parameters, it is possible that the admin could be tricked into visiting a specially crafted URI that contains the IP address of the router and malformed URI parameters
