PatchTheCVECVE-2022-24989: TerraMaster NAS through 4.2.30 allows remote WAN attackers to execute arbitrary code as root via the raidtype
CVE-2022-24989 is a critical-severity flaw (CVSS 9.8) affecting terramaster operating system. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- Critical severity
- EPSS top 2%: very likely to be exploited
- Public exploit reference
- CISA SSVC: automatable with total technical impact
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
