Summary

Linksys WAG200G through 1.01.06 contains a stored cross-site scripting flaw (CWE-79). Input in the policy_name parameter of setup.cgi is stored without neutralization, so scripts run in the browser of an administrator who views the Status > Wireless page. An authenticated attacker can save a malicious policy name from the AccessRes.htm page to trigger this. A public exploit is linked in the references.
