EUVD-2024-19878

Comprehensive Technical Analysis of EUVD-2024-19878

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2024-19878 affects IBM App Connect Enterprise versions 11.0.0.1 through 11.0.0.24 and 12.0.1.0 through 12.0.11.0. The issue arises from improper restriction of excessive authentication attempts, which can lead to sensitive information disclosure or denial of service (DoS).

Severity Evaluation:

• Base Score: 9.1 (Critical)
• Base Score Version: CVSS 3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H

The CVSS score of 9.1 indicates a critical vulnerability. The vector string highlights 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): None (N)
• Availability (A): High (H)

This vulnerability is severe due to its potential for remote exploitation without requiring user interaction or special privileges.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: An attacker can exploit this vulnerability over the network.
• Authentication Attacks: The primary attack vector involves excessive authentication attempts, which can lead to brute-force attacks or account lockout mechanisms being bypassed.

Exploitation Methods:

• Brute-Force Attacks: Attackers can attempt multiple login attempts to guess valid credentials.
• Denial of Service (DoS): By flooding the authentication mechanism with excessive requests, attackers can cause the system to become unresponsive or crash.

3. Affected Systems and Software Versions

Affected Software:

• IBM App Connect Enterprise 11.0.0.1 through 11.0.0.24
• IBM App Connect Enterprise 12.0.1.0 through 12.0.11.0

Affected Systems:

• Any system running the specified versions of IBM App Connect Enterprise.
• Systems that rely on IBM App Connect Enterprise for integration and data exchange.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Patching: Apply the latest patches and updates provided by IBM.
• Rate Limiting: Implement rate limiting on authentication attempts to prevent brute-force attacks.
• Account Lockout: Enable account lockout mechanisms after a certain number of failed login attempts.

Long-Term Mitigation:

• Monitoring: Implement continuous monitoring for suspicious login activities.
• Multi-Factor Authentication (MFA): Enforce MFA to add an additional layer of security.
• Regular Audits: Conduct regular security audits and vulnerability assessments.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to organizations using IBM App Connect Enterprise within the European Union. Given the critical nature of the vulnerability, it could lead to:

• Data Breaches: Unauthorized access to sensitive information.
• Service Disruptions: DoS attacks leading to service outages.
• Compliance Issues: Potential violations of GDPR and other regulatory requirements.

Organizations must prioritize patching and implementing robust security measures to mitigate these risks.

6. Technical Details for Security Professionals

Technical Overview:

• Vulnerability Type: Improper restriction of excessive authentication attempts.
