Edimax 7205APL
Vendor: Edimax
Type: 7205APL
Firmware: 2.40a-00
Kind of bug: Security
Description: Normally a user called addmin, has to create a password on the
Accesspoint.
When you create a back-up of the settings of your Accesspoint, it will result
in a config.bin file.
Opening the file in Notepad gave the next result:
ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ 71331234,À¨ÿÿÿ default.domainÀ¨À¨dÀ¨Èadmin
XXXXX guest
1234 WirelessXXXXXX, À¨?ÿyy À¨À¨À¨dÀ¨domain©üUoù Lg C´ ©üUoù
Lg C´é
You can see the password of the admin XXXXX (for security reasons, I have
changed the original one in XXXXX) and the password of a user called guest,
1234.
When you log in to the accesspoint with guest and 1234, you can make a backup.
With the same content like above of the admin.
It is not possible to remove the user, because it is inside the firmware. So
only a new one can solve this security problem.
