iBiioST2 - CVE Registry
CVE-2021-28667 - Unicode Payload Logging
Discovered Date: March 16, 2021
Severity: High
Attack Complexity: Low
Vulnerability: iBiioST2 v4.0 and earlier
Exploitation: Orchestral is not aware of any active malicious attempts to exploit the vulnerability
Resolution: Upgrade iBiioST2 to v4.1
Description:
This vulnerability was discovered in the underlying StackStorm v3.4.1 open-source software by StackStorm developers and affects iBiioST2 v4.0 and earlier.
The issue affects anyone who is running iBiioST2 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, iBiioST2 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?
A: Customers should upgrade as soon as practical. iBiioST2 servers are not generally accessible by external malicious actors, so exposure may be limited. However, this could be exploited by a malicious actor that has direct access to the iBiioST2 server.
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.
