This is a Vulnerability. To view all vulnerabilities, please see the Vulnerability Category page.
A hard-coded password vulnerability occurs when usernames and passwords are included in HTML comments. Because HTML comments are not displayed, it was often the mentality that normal users would not see them. It can also occur when a specific username (usually unique) does not require a password.
This example shows how usernames and passwords can be included within HTML comments:
<form name="login" action="login.php" method="post" onSubmit="return email_Submit();"> <b>Log in Address: </b> <input type="text" name="email" size="29" value=""> <b>Password: </b> <input type="password" name="password" size="29" value=""> <!-- Debugging credentials: email@example.com:abc123 --> </form>
