Comprehensive Technical Analysis of EUVD-2025-13297

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified as EUVD-2025-13297 in Agentflow from Flowring Technology is an Account Lockout Bypass vulnerability. This flaw allows unauthenticated remote attackers to perform password brute force attacks, potentially leading to unauthorized access to user accounts.

Severity Evaluation:

• Base Score: 9.8 (Critical)
• Base Score Version: 3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The CVSS score of 9.8 indicates a critical vulnerability. The vector string breaks down as follows:

• AV:N (Network): The vulnerability is exploitable over the network.
• AC:L (Low): The attack complexity is low, meaning it is relatively easy to exploit.
• PR:N (None): No privileges are required to exploit the vulnerability.
• UI:N (None): No user interaction is required.
• S:U (Unchanged): The scope of the vulnerability does not change.
• C:H (High): Confidentiality impact is high.
• I:H (High): Integrity impact is high.
• A:H (High): Availability impact is high.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: Attackers can exploit this vulnerability over the network without needing to be physically present or having any prior access.
• Brute Force Attacks: The primary exploitation method involves using automated tools to attempt multiple login attempts with different passwords until the correct one is found.

Exploitation Methods:

• Automated Scripts: Attackers can use scripts to automate the process of guessing passwords.
• Credential Stuffing: Using previously leaked credentials from other breaches to attempt logins.
• Dictionary Attacks: Using a predefined list of common passwords to attempt logins.

3. Affected Systems and Software Versions

Affected Systems:

• Product: Agentflow
• Vendor: Flowring Technology
• Version: 4.0

All systems running Agentflow version 4.0 are vulnerable to this exploit.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Patching: Apply the latest security patches provided by Flowring Technology.
• Account Lockout Policies: Implement stricter account lockout policies to limit the number of failed login attempts.
• Multi-Factor Authentication (MFA): Enforce MFA to add an additional layer of security.
• Monitoring: Increase monitoring for unusual login attempts and failed login attempts.

Long-Term Mitigation:

• Regular Audits: Conduct regular security audits to identify and mitigate similar vulnerabilities.
• User Education: Educate users on the importance of strong, unique passwords and the risks associated with password reuse.
• Intrusion Detection Systems (IDS): Deploy IDS to detect and respond to brute force attacks in real-time.
