Description:
Kristian Hermansen has reported a vulnerability in Linksys WET11, which can be exploited by malicious people to bypass certain security restrictions.
The vulnerability is caused due to an error where the device password can be changed without providing the old password. This can be exploited to set a blank password and gain access to the device.
Example:
http://[victim]/changepw.html?data=........................
NOTE: In version 1.5.4, successful exploitation requires that a user has logged in recently.
