Subject: CVE-2021-38294: Apache Storm: Shell Command Injection
 Vulnerability in Nimbus Thrift Server 

Severity: high


A Command Injection vulnerability exists in the getTopologyHistory service of the Apache Storm 2.x prior to 2.2.1 and Apache Storm 1.x prior to 1.2.4. A specially crafted thrift request to the Nimbus server allows Remote Code Execution (RCE) prior to authentication. 


Apache Storm 2.2.x users should upgrade to version 2.2.1 or 2.3.0
Apache Storm 2.1.x users should upgrade to version 2.1.1
Apache Storm 1.x users should upgrade to version 1.2.4


Apache Storm would like to thank @pwntester Alvaro Muñoz of the GitHub Security Lab team for reporting this issue.
