Comprehensive Technical Analysis of EUVD-2025-198348

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2025-198348, also known as CVE-2025-10571, is an Authentication Bypass Using an Alternate Path or Channel vulnerability affecting ABB Ability Edgenius versions 3.2.0.0 and 3.2.1.1. The CVSS (Common Vulnerability Scoring System) base score of 9.4 indicates a critical severity level. The CVSS vector breakdown is as follows:

• AV:A (Adjacent Network): The attacker must be on the same network as the target.
• AC:L (Low Complexity): The attack requires low skill or resources.
• AT:N (No Authentication): No authentication is required to exploit the vulnerability.
• PR:N (No Privileges Required): No privileges are required to exploit the vulnerability.
• UI:N (No User Interaction): No user interaction is required.
• VC:H (High Confidentiality Impact): The vulnerability has a high impact on confidentiality.
• VI:H (High Integrity Impact): The vulnerability has a high impact on integrity.
• VA:H (High Availability Impact): The vulnerability has a high impact on availability.
• SC:H (High Scope Change): The vulnerability can affect other components beyond the initial target.
• SI:H (High Scope Integrity): The vulnerability can affect the integrity of other components.
• SA:H (High Scope Availability): The vulnerability can affect the availability of other components.

This high severity score underscores the critical nature of the vulnerability, necessitating immediate attention and mitigation.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector for this vulnerability is through an adjacent network, meaning an attacker must be on the same local network as the target system. Given the low complexity and lack of required authentication or user interaction, an attacker could exploit this vulnerability by:

• Network Scanning: Identifying the target system on the local network.
• Alternate Path Exploitation: Using an alternate path or channel to bypass the authentication mechanism.
• Automated Tools: Utilizing automated tools to scan for and exploit the vulnerability, given its low complexity.

3. Affected Systems and Software Versions

The affected systems are:

• ABB Ability Edgenius version 3.2.0.0
• ABB Ability Edgenius version 3.2.1.1
