Official description
In WODESYS WD-R608U router (also known as WDR122B V2.0 and WDR28) admin password is stored in configuration file as plaintext and can be obtained by unauthorized user by direct references to the resource in question. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version WDR28081123OV1.01 was tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.

The underlying weakness: Plaintext Storage of a Password
The product stores a password in plaintext within resources such as memory or files.
How developers prevent this class of flaw
- Avoid storing passwords in easily accessible locations.
- Consider storing cryptographic hashes of passwords as an alternative to storing in plaintext.
- A programmer might attempt to remedy the password management problem by obscuring the password with an encoding function, such as base 64 encoding, but this effort does not adequately protect the password because the encoding can be detected and decoded easily.
