CVE-2025-8611

Estado: AnalizadaCrítica (9.8)—

AOMEI Cyber Backup Missing Authentication for Critical Function Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of AOMEI Cyber Backup. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the DaoService service, which listens on TCP port 9074 by default. The issue results from the lack of authentication prior to allowing access to functionality. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-26158.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK
