CVE-2025-8610
Published: 20 August 2025
Summary
CVE-2025-8610 is a critical-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Aomei Cyber Backup. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 16.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
AOMEI Cyber Backup contains a missing authentication vulnerability in its StorageNode service, which listens on TCP port 9075 by default. The flaw, tracked as CVE-2025-8610 and originally ZDI-CAN-26156, permits unauthenticated remote access to critical functionality and results in arbitrary code execution with SYSTEM privileges on affected installations. It carries a CVSS 3.0 score of 9.8 and is classified under CWE-306.
Remote attackers can exploit the issue over the network without credentials or user interaction to run arbitrary code on the target system. Successful exploitation grants full control in the context of the SYSTEM account, enabling complete compromise of the backup server.
The sole referenced advisory from the Zero Day Initiative at https://www.zerodayinitiative.com/advisories/ZDI-25-808/ addresses the issue but does not detail specific mitigation steps in the provided information.
EPSS for this CVE rose from a low initial value to a peak of 0.0466, indicating emerging exploitation interest after disclosure that warrants renewed attention from defenders.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requires established identification and authentication to unlock, mitigating missing authentication for continued system access.
Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements.
Authorizing mobile device connections to organizational systems ensures authentication is performed for this critical access function.
Guarantees critical functions are protected by mandatory invocation of the access control mechanism.
Auditing sessions makes it possible to detect access to critical functions without required authentication.
The assessment process confirms authentication is present and effective for critical functions, preventing exploitation from missing authentication.
Certification assesses that critical functions have required authentication controls in place.
Disabling non-essential functions and services eliminates the need to secure them, reducing exposure from missing authentication on unnecessary components.
