James E. King III updated THRIFT-3165:
--------------------------------------
Summary: Disable unsafe TLSv1.0 and TLSv1.1 by default (was: Remove
TSSLSocket::SSLProtocol and require subclass of SSLContext to control TLS
negotiation)
> Disable unsafe TLSv1.0 and TLSv1.1 by default
> ---------------------------------------------
>
> Key: THRIFT-3165
> URL: https://issues.apache.org/jira/browse/THRIFT-3165
> Project: Thrift
> Issue Type: Improvement
> Components: C++ - Library
> Affects Versions: 0.9.2
> Reporter: James E. King III
> Priority: Major
> Labels: SSL, SSLSocketFactory, Security, TLS
>
> Thrift provides an SSL implementation and implements some best practices (for
> example, SSLv2 and SSLv3 are disabled). The current mechanism in the C++
> library to control the protocol negotiation is unnecessarily complex.
> The current behavior is to use an enumeration to set the protocol level. The
> methods these call are deprecated in OpenSSL 1.1 and do not provide the
> desired control.
> The proposed new behavior is to:
> * Remove SSLProtocol
> * Require the consumer to subclass SSLContext and call SSL_CTX_set_option to
> disable certain behaviors, like negotiation protocol levels.
> For example the following SSLContext subclass will ensure connections are at
> TLSv1_2 or later:
> {noformat}
> class SSLContextOnlyTLSv12OrLater : public SSLContext
> {
> public:
> SSLContextOnlyTLSv12OrLater() : SSLContext()
> {
> // SSLContext already disables SSLv2 and SSLv3
> SSL_CTX_set_options(get(), SSL_OP_NO_TLSv1); // This is TLSv1_0
> SSL_CTX_set_options(get(), SSL_OP_NO_TLSv1_1);
> }
> };
> {noformat}
