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.
Conclusion & alert: CVE-2022-24989 is rated High Exploit Risk (90.5/100): CVSS Critical severity, with high exploitation likelihood (EPSS 83.68%, 99th percentile). Core evidence: 3 public exploit reference(s) are indexed (Exploit-DB). EPSS rose +1.57% over the last day, indicating growing attacker interest. Mandatory action: Public exploits are available—assess exposure, apply mitigations, and prioritize patching.
Risk is dynamic; we continuously reassess and refresh what is shown on this page as upstream context changes.
