No Password Length Verification

Password Policy Vulnerability 

No Password Length Verification

  

"No Password Length Verification" refers to a scenario or condition where a system or application does not enforce a specific minimum or maximum length for passwords during the authentication process. In other words, users can set passwords of any length, including very short passwords or excessively long passwords, without encountering any restrictions or limitations imposed by the system.

Password length verification is commonly implemented by organizations and online platforms to ensure that users choose passwords that meet certain complexity requirements. These requirements may include minimum and maximum length, character diversity (such as a combination of uppercase and lowercase letters, numbers, and special characters), and avoidance of common or easily guessable passwords.

The Minimum password length policy setting determines the least number of characters that can make up a password for a user account. You can set a value of between 1 and 14 characters, or you can establish that no password is required by setting the number of characters to 0.

How To Find ?

 

STEP #1: First of all go to any site then click on its sign up now option.

STEP #2: After that fill all the options except the password option.

STEP #3: Then go to notepad and create a password of 100000 characters and copy it

STEP #4: Then paste that password in the password option of the site and sign up the Account.

STEP #5: and verify account then sign in 

STEP #6: Now you can see that the account has been sign in and the long password has been accepted.

Impact : 

 

Password length refers to the number of characters (letters, numbers, punctuation marks, etc.) in a password. Experts recommend using longer passwords when possible. The longer a password is, the more possible permutations it has, making it harder and harder for cybercriminals to crack.

As the response is seen, the server might not be able to handle such lengthy passwords coming from different machines simultaneously. The attacker can perform a DDOS attack by using this vulnerability


Mitigation : 

If you are dealing with a system or application that lacks password length verification, there are several mitigation strategies you can consider to enhance security:

1. Implement a Minimum Password Length: 

Introduce a minimum password length requirement to ensure that users select passwords of sufficient complexity. A recommended minimum length is generally around 8 to 10 characters, but you can adjust it based on your specific security needs.

2.Monitor and Detect Suspicious Activity: 

Implement robust monitoring systems that can detect unusual login patterns or suspicious activity, such as multiple failed login attempts. This can help identify and prevent unauthorized access to user accounts, even if weak passwords are used.

3.Regularly Update and Patch the System: 

Keep the system up to date with the latest security patches and updates to address any potential vulnerabilities. Regularly reviewing and updating the authentication process can help mitigate risks associated with weak passwords.

Remember, while these mitigation strategies can enhance security, it is still advisable to address the lack of password length verification at the system level to enforce consistent password policies and ensure stronger security overall.
