Detailsinfo

A vulnerability was found in TerraMaster NAS up to 4.2.30 on PHP. It has been rated as critical. Affected by this issue is some unknown processing of the file api.php?mobile/createRaid of the component Shell Metacharacter Handler. The manipulation of the argument raidtype/diskstring with an unknown input leads to a os command injection vulnerability. Using CWE to declare the problem leads to CWE-78.

Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.
