Description

This module targets an authentication bypass vulnerability in the mini_http binary of several Netgear Routers
running firmware versions prior to 1.2.0.88, 1.0.1.80, 1.1.0.110, and 1.1.0.84. The vulnerability allows
unauthenticated attackers to reveal the password for the admin user that is used to log into the
router's administrative portal, in plaintext.

Once the password has been been obtained, the exploit enables telnet on the target router and then utiltizes
the auxiliary/scanner/telnet/telnet_login module to log into the router using the stolen credentials of the
admin user. This will result in the attacker obtaining a new telnet session as the "root" user.

This vulnerability was discovered and exploited by an independent security researcher who reported it to SSD.
