Identity Management / Same Password Accepted in "Password Change" Functionality

Web and API

Description

Same password accepted in "password change" functionality is a web and API vulnerability that falls under identity management (CWE-822). This vulnerability occurs when an application allows the same password to be used for both new and old passwords when changing a user's password. This is a critical security flaw as it allows an attacker to use the same password to gain access to the application or system. By using the same password, an attacker can reset the password of a user and gain access to their account.

Risk

This vulnerability can lead to an attacker gaining access to a user's account, which could result in data breaches, unauthorized access to sensitive information, and other malicious activities. This vulnerability can also lead to users being locked out of their accounts, which can lead to significant disruption and loss of user trust.

Solution

Organizations should take steps to prevent this vulnerability from occurring. This includes ensuring that the application does not allow the same password to be used for both new and old passwords when changing a user's password. Additionally, organizations should require users to regularly change their passwords and use strong passwords.
