Background
Apache Thrift is an open-source software framework used for scalable cross-language services development. It allows efficient and reliable communication between different programming languages. The vulnerability affects the Apache Thrift Java client library versions 0.5.0 to 0.9.3-1 and 0.10.0 to 0.12.0. This vulnerability allows bypassing SASL negotiation isComplete validation in the org.apache.thrift.transport.TSaslTransport class. In production settings, an assert used to determine if the SASL handshake had successfully completed could be disabled, leading to incomplete validation.
