CWE

CWE-620 – Unverified Password Change

Read Time:1 Minute, 0 Second

Description

When setting a new password for a user, the product does not require knowledge of the original password, or using another form of authentication.

This could be used by an attacker to change passwords for another user, thus gaining the privileges associated with that user.

Modes of Introduction:

– Architecture and Design

 

 

Related Weaknesses

CWE-287

 

Consequences

Access Control: Bypass Protection Mechanism, Gain Privileges or Assume Identity

 

Potential Mitigations

Phase: Architecture and Design

Description: 

When prompting for a password change, force the user to provide the original password in addition to the new password.

Phase: Architecture and Design

Description: 

Do not use “forgotten password” functionality. But if you must, ensure that you are only providing information to the actual user, e.g. by using an email address or challenge question that the legitimate user already provided in the past; do not allow the current user to change this identity information until the correct password has been provided.

CWE

CWE-522 – Insufficiently Protected Credentials

Read Time:58 Second

Description

The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.

Modes of Introduction:

– Architecture and Design

 

 

Related Weaknesses

CWE-287
CWE-287
CWE-668

 

Consequences

Access Control: Gain Privileges or Assume Identity

An attacker could gain access to user accounts and access sensitive data used by the user accounts.

 

Potential Mitigations

Phase: Architecture and Design

Description: 

Use an appropriate security mechanism to protect the credentials.

Phase: Architecture and Design

Description: 

Make appropriate use of cryptography to protect the credentials.

Phase: Implementation

Description: 

Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
