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.
