EUVD-2024-32850

Comprehensive Technical Analysis of EUVD-2024-32850

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability in E-WEBInformationCo.'s FS-EZViewer(Web) allows a remote attacker to obtain the database configuration file path through the webpage source code without requiring authentication. This exposure enables the attacker to access the database credentials with the highest privilege and the database host IP address, leading to unauthorized database access and manipulation.

Severity Evaluation: The vulnerability has a CVSS Base Score of 9.8, which is classified as Critical. The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H indicates the following:

• Attack Vector (AV): Network (N) - The vulnerability is exploitable over the network.
• Attack Complexity (AC): Low (L) - The attack requires minimal skill and resources.
• Privileges Required (PR): None (N) - No authentication is required to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required.
• Scope (S): Unchanged (U) - The vulnerability does not change the security scope.
• 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

Attack Vectors:

• Unauthenticated Access: An attacker can access the webpage source code without logging in, exposing the database configuration file path.
• Database Configuration Exposure: The exposed path allows the attacker to retrieve the database credentials and host IP address.
• Database Manipulation: With the obtained credentials, the attacker can connect to the database and perform unauthorized actions such as adding, modifying, or deleting database contents.

Exploitation Methods:

• Source Code Analysis: The attacker analyzes the webpage source code to locate the database configuration file path.
• Path Traversal: The attacker uses the exposed path to access the configuration file.
• Database Connection: The attacker uses the retrieved credentials to connect to the database and execute SQL commands.

3. Affected Systems and Software Versions

Affected Systems:

• FS-EZViewer(Web) versions earlier than or equal to 10.4.0.x

Vendor:

• E-WEBInformationCo.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patch Management: Ensure that all instances of FS-EZViewer(Web) are updated to a version higher than 10.4.0.x.
• Access Controls: Implement strict access controls to restrict unauthorized access to the webpage source code.
• Monitoring: Enhance monitoring and logging to detect any unauthorized access attempts.

Long-Term Strategies:

• Code Review: Conduct thorough code reviews to identify and remediate similar vulnerabilities.
• Security Training: Provide security training for developers to prevent future exposure of sensitive information.
• Regular Audits: Perform regular security audits and vulnerability assessments.

5. Impact on European Cybersecurity Landscape
