Weaknesses

Improper Authentication

When an actor claims to have a given identity, the software does not prove or insufficiently proves that the claim is correct.

Insufficient Session Expiration

According to WASC, "Insufficient Session Expiration is when a web site permits an attacker to reuse old session credentials or session IDs for authorization."

Insufficiently Protected Credentials

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

Session Fixation

Authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal au...

Unprotected Storage of Credentials

Storing a password in plaintext may result in a system compromise.

Unprotected Transport of Credentials

Login pages do not use adequate measures to protect the user name and password while they are in transit from the client to the server.

Unverified Password Change

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

Use of Single-factor Authentication

The use of single-factor authentication can lead to unnecessary risk of compromise when compared with the benefits of a dual-factor authentication scheme.

Weak Password Recovery Mechanism for Forgotten Password

The software contains a mechanism for users to recover or change their passwords without knowing the original password, but the mechanism is weak.
