An Information Disclosure vulnerability exists in the my config file in NEtGEAR WGR614 v7 and v9, which could let a malicious user recover all previously used passwords on the device, for both the control panel and WEP/WPA/WPA2, in plaintext. This is a different issue than CVE-2012-6340.
Netgear WGR614 has a hardcoded credential for serial programming on an EEPROM. It also keeps several copies of configuration files with your credentials stored in the clear.
