Comprehensive Technical Analysis of EUVD-2025-17103

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-17103 pertains to a missing authentication mechanism for critical functions within the client application of the Soar Cloud HRD Human Resource Management System (HRM). This flaw allows remote attackers to bypass authentication and gain unauthorized access to critical application functions.

Severity Evaluation:

• CVSS Base Score: 9.3 (Critical)
• CVSS Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N

The high base score of 9.3 indicates a critical vulnerability. The CVSS vector breakdown shows that the vulnerability can be exploited remotely (AV:N) with low complexity (AC:L), does not require user interaction (UI:N), and has high impact on confidentiality, integrity, and availability (VC:H, VI:H, VA:H).

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: Attackers can exploit this vulnerability over the network without needing physical access to the system.
• Unauthenticated Access: The lack of authentication allows attackers to access critical functions without needing valid credentials.

Exploitation Methods:

• Network Scanning: Attackers can scan for vulnerable systems connected to the internet.
• Automated Scripts: Malicious actors can use automated scripts to exploit the vulnerability, potentially leading to widespread attacks.
• Data Exfiltration: Once access is gained, attackers can exfiltrate sensitive data, manipulate records, or disrupt services.

3. Affected Systems and Software Versions

Affected Systems:

• Soar Cloud HRD Human Resource Management System

Affected Software Versions:

• All versions up to and including 7.3.2025.0408

4. Recommended Mitigation Strategies

Immediate Actions:
