Risk Analysis

ASUSTOR Data Master (ADM) contains a stack-based buffer overflow vulnerability due to insufficient data size validation. This flaw allows remote, unauthenticated attackers to execute arbitrary code on the affected device.

No public exploit is currently known, and the vulnerability is not in the CISA KEV catalog.

Recommended Action

Upgrade to a version of ADM beyond 4.0.6.REG2, 4.1.0, or 4.2.0.RE71 to ensure proper data size validation.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2023-30770 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

From a weakness classification perspective (CWE-787): Out-of-bounds write vulnerabilities can lead to data corruption, crashes, or arbitrary code execution.
