CVE-2022-24989 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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.. EPSS estimates a 31.88% chance of exploitation in the next 30 days.
