Description:
Some vulnerabilities have been reported in two Asus ADSL routers (AAM6000EV and AAM6330BI), which can be exploited by malicious people to gain knowledge of sensitive information.

The vulnerabilities are caused due to an access control error when the integrated web server is enabled. Anyone from the LAN can access the resources "userdata" and "snmpinit", which may disclose a list of usernames and passwords in plain text as well as the SNMP community strings.

Examples:
http://[victim]/userdata
http://[victim]/snmpinit

Solution:
Disable the integrated web server or restrict access to it.
