CVE-2022-21279: Oracle MySQL Cluster Management API Stack-based Buffer Overflow Remote Code Execution Vulnerability
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Oracle MySQL Cluster. Authentication is not required to exploit this vulnerability. The specific flaw exists within the Management API. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the service account.
