Ken Giusti created QPID-4918:
--------------------------------
Summary: Python client does not enforce SSL certificate validation
even if CAs configured
Key: QPID-4918
URL: https://issues.apache.org/jira/browse/QPID-4918
Project: Qpid
Issue Type: Bug
Components: Python Client
Affects Versions: 0.20
Reporter: Ken Giusti
Assignee: Ken Giusti
Priority: Blocker
Fix For: 0.22
With SSL, the Python client allows the application to specify the trusted CAs
that should be used to validate the remote broker's certificate.
However, there is a bug in the implementation that does not enforce the
validation. This bug allows the SSL connection to be established even if the
remote does not provide a valid certificate.
This bug is a security risk. The application has configured a CA to use to
validate the remote, but that CA is silently ignored and the remote is allowed
to connect without validation. To the application, it appears as if the remote
certificate has been verified and the remote has been authorized, when in fact
that hasn't happened.
A CVE has been created for this issue: CVE-2013-1909
