CVE-2019-0223: High severity Apache qpid vulnerability
Withdrawn Advisory This advisory has been withdrawn because the vulnerability only affects the Qpid Proton C library and not org.apache.qpid:proton-j. This link has been maintained to preserve external references.
Original Description
While investigating bug PROTON-2014, we discovered that under some circumstances Apache Qpid Proton versions 0.9 to 0.27.0 (C library and its language bindings) can connect to a peer anonymously using TLS even when configured to verify the peer certificate while used with OpenSSL versions before 1.1.0. This means that an undetected man in the middle attack could be constructed if an attacker can arrange to intercept TLS traffic.
Other sources
The TLS support in Apache Qpid Proton 0.9 - 0.27.0 when using OpenSSL prior to 1.1.0 can under some circumstances connect as a client to a TLS server that offers anonymous ciphers irrespective of whether the client was configured to verify the server's certificate or certificate against the hostname used to connect. This means that an undetected man in the middle attack could be constructed if an attacker can arrange to intercept TLS traffic. This includes the Qpid Proton C library, and all language binding libraries using it. This attack will not work if client certificate authentication is in use as anonymous ciphers cannot be used in this case.
