1	Notice on the Apache Log4j2 remote code execution vulnerability (CVE-2021-44228)	Apache Log4j2 has a remote code execution vulnerability (CVE-2021-44228). When Apache Log4j2 processes user input during log processing, attackers can construct special requests to trigger remote code execution. Apache Log4j2 is used in Fabric_SDK_Gateway_Java and Fabric_SDK_Java provided by BCS (for encryption using Chinese cryptographic algorithms) and those provided by Hyperledger Fabric. It is also used in the corresponding demos App_Gateway_Java_Demo, App_Java_Src_Demo, and App_Java_Jar_Demo. The vulnerability in these components has been fixed in the CN North-Beijing4 region. If you use these components, go to the BCS console, switch to the CN North-Beijing4 region, obtain the latest version from Interactive Walkthroughs, and perform an upgrade as soon as possible. Before fixing the vulnerability in your blockchain application, ensure that the input source of your blockchain application is trusted.
