Weakness ID: 523 (Weakness Variant)Status: Incomplete
+ Description

Description Summary

Login pages not using adequate measures to protect the user name and password while they are in transit from the client to the server.
+ Time of Introduction
  • Architecture and Design
+ Potential Mitigations

Enforce SSL use for the login page or any page used to transmit user credentials or other sensitive information. Even if the entire site does not use SSL, it MUST use SSL for login. Additionally, to help prevent phishing attacks, make sure that SSL serves the login page. SSL allows the user to verify the identity of the server to which they are connecting. If the SSL serves login page, the user can be certain they are talking to the proper end system. A phishing attack would typically redirect a user to a site that does not have a valid trusted server certificate issued from an authorized supplier.

+ Background Details

SSL (Secure Socket Layer) provides data confidentiality and integrity to HTTP. By encrypting HTTP messages, SSL protects from attackers eavesdropping or altering message contents.

+ Other Notes

Login pages should always employ SSL to protect the user name and password while they are in transit from the client to the server. Lack of SSL use exposes the user credentials as clear text during transmission to the server and thus makes the credentials susceptible to eavesdropping.
