Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

TerraMaster NAS through 4.2.30 allows remote WAN attackers to execute arbitrary code as root via the raidtype and diskstring parameters for PHP Object Instantiation to the api.php?mobile/createRaid URI. (Shell metacharacters can be placed in raidtype because popen is used without any sanitization.) The credentials from CVE-2022-24990 exploitation can be used.
