Supported platform(s): Linux, Unix
Target service / protocol: -
Target network port(s): 6627
List of CVEs: CVE-2021-38294
This module exploits an unauthenticated command injection vulnerability within the Nimbus service component of Apache Storm. The getTopologyHistory RPC method method takes a single argument which is the name of a user which is concatenated into a string that is executed by bash. In order for the vulnerability to be exploitable, there must have been at least one topology submitted to the server. The topology may be active or inactive, but at least one must be present. Successful exploitation results in remote code execution as the user running Apache Storm. This vulnerability was patched in versions 2.1.1, 2.2.1 and 1.2.4. This exploit was tested on version 2.2.0 which is affected.
Module Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Reliability:
- repeatable-session: The module is expected to get a shell every time it runs.
Stability:
- crash-safe: Module should not crash the service.
Side Effects:
- ioc-in-logs: Module leaves signs of a compromise in a log file (Example: SQL injection data found in HTTP log).
- artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.

Vulnerable Application
This module exploits an unauthenticated command injection vulnerability within the Nimbus service
component of Apache Storm. The getTopologyHistory() RPC method method takes a single argument
which is the name of a user which is concatenated into a string that is executed by bash. In
order for the vulnerability to be exploitable, there must have been at least one topology
submitted to the server. The topology may be active or inactive, but at least one must be present.
Successful exploitation results in remote code execution as the user running Apache Storm.
This vulnerability was patched in versions 2.1.1, 2.2.1 and 1.2.4. This exploit was tested on version 2.2.0 which is affected.
Verification Steps
- Setup a minimal Storm cluster using the published docker images. The following steps were adapted from Docker
reference.
- The following steps can be executed to start up a minimal Storm cluster, but requires the Storm Starter jar
to exist in the current directory as
topology.jar. Follow the steps on the projects page to build it with Maven. Storm Starter v2.4.0 was used for testing.
- The following steps can be executed to start up a minimal Storm cluster, but requires the Storm Starter jar
to exist in the current directory as
# 1. Start a ZooKeeper server:
docker run -d --rm --name some-zookeeper zookeeper
# 2. Start a Nimbus server:
docker run -p 6627:6627 -d --rm --name some-nimbus --link some-zookeeper:zookeeper \
