- Abstraction:Variant
- Structure:Simple
- Status:Incomplete

Weakness Name
Missing Validation of OpenSSL Certificate
Description
The product uses OpenSSL and trusts or uses a certificate without using the SSL_get_verify_result() function to ensure that the certificate satisfies all necessary security requirements.
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.
Common Consequences
Scope: Confidentiality
Impact: Read Application Data
Notes: The data read may not be properly secured, it might be viewed by an attacker.
Scope: Access Control
Impact: Bypass Protection Mechanism, Gain Privileges or Assume Identity
Notes: Trust afforded to the system in question may allow for spoofing or redirection attacks.
Scope: Access Control
Impact: Gain Privileges or Assume Identity
Notes: 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. 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.
