Identity Management / No Password Change Functionality

Mobile AppWeb and APIInfrastructure

Description No password change functionality is a vulnerability in the identity management of IT infrastructure, mobile apps and web and API applications. It is classified as CWE-257, which is described as "Failure to Change a Password in a timely manner". According to OWASP Testing Guide, this type of vulnerability occurs when the user is not required to change the password after a predetermined amount of time. This can create a security risk since a malicious user can gain access to sensitive data if the same password is used for a long period of time.

Risk The risk of no password change functionality is high. If a malicious user is able to gain access to the system, they can view or modify sensitive data or even take control of the system. This can lead to data loss, financial loss, and even reputational damage.

Solution The solution to this vulnerability is to implement a system that requires users to change their password after a certain amount of time. This system should also enforce strong password policies with a combination of letters, numbers, and special characters. It should also enforce a lockout policy after a certain number of failed attempts.

Example The following example code enforces a password change policy of 30 days, a minimum password length of 10 characters, and a lockout policy of three failed attempts.

if (time_difference_in_seconds > 30 * 24 * 3600) 
  // prompt user to change password 
if (strlen(password) < 10) 
  // prompt user to create a longer password 
if (failed_attempts > 3) 
  // lock user out
