ABSTRACT

Storing a password in plaintext could result in a system compromise.

EXPLANATION

Password management issues occur when a password is stored in plaintext in an application's configuration files or other data store.

Example: The following code reads a password from the registry and uses the password to connect to a database.


...
RegQueryValueEx(hkey,TEXT(.SQLPWD.),NULL,
NULL,(LPBYTE)pwd, &size);
rc = SQLConnect(*hdbc, server, SQL_NTS, uid,
SQL_NTS, pwd, SQL_NTS);
...


This code will run successfully, but anyone who has access to the registry key used to store the password can read the value of pwd. If a devious employee has access to this information, they can use it to break into the system.
