ZyXEL Gateways Vulnerability Research: http://www.procheckup.com/Hacking_ZyXEL_Gateways.pdf
This paper is the result of various security assessments performed on
several ZyXEL Prestige devices in both, a controlled environment
(computer lab) and production environments during several penetration tests.
There are two types of attacks featured in this paper which we believe
might be potentially new:
- Persistent XSS via SNMP
- Remote wardriving over the Internet
Additionally, the paper is full of other goodies such as:
- Privilege escalation: it allows retrieving administrative settings
(i.e.: WEP key, ISP and dynamic DNS credentials) and also altering such
settings
- SNMP read and SNMP *write* access enabled by default: not only we
demonstrate how to change settings but we also show how to obtain the
credentials for the Dynamic DNS service in cleartext
- Poor session management allows hijacking of admin sessions
- Authentication vulnerable to replay and password cracking attacks
- Disclosure of credentials: several types of credentials travel in the
clear when being submitted by the user, and also when being returned
from the web interface back to the browser
