What is CVE-2022-33915?

A vulnerability exists in versions of the AWS Apache Log4j hotpatch package prior to log4j-cve-2021-44228-hotpatch-1.3.5 due to a race condition. This issue allows local users to escalate privileges by executing a specific Java process that performs a command (exec()) on an SUID binary. The hotpatch script, which is intended as a temporary fix for other vulnerabilities, inadvertently provides a method for users to manipulate its execution context, granting unauthorized elevated permissions.
