Older versions of SSL/TLS protocol like "SSLv3" have been proven to be insecure.
|
|
This rule raises an issue when an SSL/TLS context is created with an insecure protocol version, i.e. when one of the following constants is detected in the code:
|
|
|
|
* <code>OpenSSL.SSL.SSLv3_METHOD</code> (Use instead <code>OpenSSL.SSL.TLSv1_2_METHOD</code>)
|
|
* <code>ssl.PROTOCOL_SSLv3</code> (Use instead <code>ssl.PROTOCOL_TLSv1_2</code>)
|
|
|
|
Protocol versions different from TLSv1.2 and TLSv1.3 are considered insecure.

== Noncompliant Code Example
|
|
|
|
----
|
|
from OpenSSL import SSL
|
|
|
|
SSL.Context(SSL.SSLv3_METHOD) # Noncompliant
|
|
----
|
|
|
|
----
|
|
import ssl
|
|
|
|
ssl.SSLContext(ssl.PROTOCOL_SSLv3) # Noncompliant
|
|
----
|
|
|
|
== Compliant Solution
|
|
|
|
----
|
|
from OpenSSL import SSL
|
|
|
|
SSL.Context(SSL.TLSv1_2_METHOD) # Compliant
|
|
----
|
|
|
|
----
|
|
import ssl
|
|
|
|
ssl.SSLContext(ssl.PROTOCOL_TLSv1_2) # Compliant
