Symphony - CVE Registry

CVE-2021-28667 - Unicode Payload Logging

Discovered Date: March 16, 2021

Severity: High

Attack Complexity: Low

Vulnerability: Composer v4.0 and earlier

Exploitation: Orchestral is not aware of any active malicious attempts to exploit the vulnerability

Resolution: Upgrade Composer to v4.1

Description:
This vulnerability was discovered in the underlying StackStorm v3.4.1 open-source software by StackStorm developers and affects Composer v4.0 and earlier.

The issue affects anyone who is running Composer under Python 3 and does not have a system locale / encoding which is used for StackStorm service processes (st2api, st2actionrunner, etc.) set to UTF-8. Under such conditions, if the system receives a payload with unicode characters which also results in the payload being logged, Composer process would go into an infinite-loop trying to decode that payload. This would cause the affected service to have a high CPU utilization and also service log file to grow either until the process is killed or all the available disk space is exhausted.

Frequently Asked Questions:

Q: When should I upgrade?

Q: My server has Python 2 installed, not Python 3. Am I affected by this?
A: No, this only impacts servers with Python 3.

Q: Are there exploits available for this vulnerability?
A: Orchestral is not aware of any active malicious attempts to exploit the vulnerability.
