Comprehensive Technical Analysis of EUVD-2025-27546

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability EUVD-2025-27546 pertains to the use of unmaintained third-party components (CWE-1104) in the NuGet dependency components within AxxonSoft Axxon One VMS versions 2.0.0 through 2.0.4 on Windows. This vulnerability allows a remote attacker to execute arbitrary code or bypass security features by exploiting vulnerable third-party packages such as Google.Protobuf, DynamicData, System.Runtime.CompilerServices.Unsafe, and others.

Severity Evaluation: The vulnerability has a CVSS base score of 9.8, which is classified as critical. The CVSS vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H indicates the following:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Scope (S): Unchanged (U)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): High (H)

This high severity score underscores the critical nature of the vulnerability, which can lead to significant impacts on confidentiality, integrity, and availability.
