Read Application Data

Affected security scopes: Confidentiality

The data read may not be properly secured - it might be viewed by an attacker.
Bypass Protection MechanismGain Privileges or Assume Identity

Affected security scopes: Access Control

Trust afforded to the system in question may allow for spoofing or redirection attacks.
Gain Privileges or Assume Identity

Affected security scopes: Access Control

If the certificate is not checked, it may be possible for a redirection or spoofing attack to allow a malicious host with a valid certificate to provide data under the guise of a trusted host. While the attacker in question may have a valid certificate, it may simply be a valid certificate for a different site. This could allow an attacker to use an invalid certificate to claim to be a trusted host, use expired certificates, or conduct other attacks that could be detected if the certificate is properly validated. In order to ensure data integrity, we must check that the certificate is valid, and that it pertains to the site we wish to access.
