Severity ?

9.8 (Critical) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

CWE

CWE-502 - Deserialization of Untrusted Data

Summary

This vulnerability allows remote attackers to execute arbitrary code on affected installations of VEEAM One Agent 9.5.4.4587. Authentication is not required to exploit this vulnerability. The specific flaw exists within the PerformHandshake method. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of the service account. Was ZDI-CAN-10400.
