EUVD-2023-41632

Comprehensive Technical Analysis of EUVD-2023-41632

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2023-41632 pertains to weak password requirements for Administrator account creation in I-doit pro 25 and below, as well as I-doit open 25 and below. This weakness allows attackers to easily guess users' passwords via brute-force attacks. The CVSS (Common Vulnerability Scoring System) base score of 9.8 indicates a critical severity level. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H breaks down as follows:

• Attack Vector (AV): Network (N) - The vulnerability can be exploited remotely over the network.
• Attack Complexity (AC): Low (L) - The attack requires minimal skill or resources.
• Privileges Required (PR): None (N) - No privileges are required to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required.
• Scope (S): Unchanged (U) - The vulnerability does not affect other systems or components.
• Confidentiality (C): High (H) - The vulnerability results in a high impact on confidentiality.
• Integrity (I): High (H) - The vulnerability results in a high impact on integrity.
• Availability (A): High (H) - The vulnerability results in a high impact on availability.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector is a brute-force attack targeting the Administrator account. Attackers can leverage automated tools to systematically guess weak passwords until they gain access. Once the Administrator account is compromised, attackers can:

• Upload Malicious Plugins: As indicated in the references, attackers can upload malicious plugins to gain further control over the system.
• Remote Code Execution (RCE): With Administrator access, attackers can execute arbitrary code on the server, leading to complete system compromise.
• Data Exfiltration: Attackers can exfiltrate sensitive data, including configuration files, user data, and other critical information.

3. Affected Systems and Software Versions

The vulnerability affects:

• I-doit pro 25 and below
• I-doit open 25 and below

Users of these versions are at risk and should prioritize updating to a patched version or implementing mitigation strategies.

4. Recommended Mitigation Strategies

To mitigate the risk associated with this vulnerability, organizations should:

• Update Software: Immediately update to the latest version of I-doit pro and I-doit open that addresses this vulnerability.
• Enforce Strong Password Policies: Implement strong password policies that require complex passwords and regular password changes.
• Enable Multi-Factor Authentication (MFA): Use MFA to add an additional layer of security for Administrator accounts.
• Monitor for Suspicious Activity: Implement monitoring and alerting for unusual login attempts or activities indicative of a brute-force attack.
• Limit Administrative Access: Restrict administrative access to only trusted and necessary personnel.
• Regular Security Audits: Conduct regular security audits to identify and remediate weak passwords and other vulnerabilities.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to organizations using I-doit pro and I-doit open within the European Union. Given the critical nature of the vulnerability, it could lead to widespread data breaches, loss of sensitive information, and disruption of services. The high CVSS score underscores the urgency for organizations to address this issue promptly to prevent potential cyber-attacks.
