EUVD-2024-50261

Comprehensive Technical Analysis of EUVD-2024-50261

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified in the AIM LINE Marketing Platform from Esi Technology (EUVD-2024-50261) is critical. The platform does not properly validate a specific query parameter, allowing unauthenticated remote attackers to inject arbitrary FetchXml commands. This can lead to reading, modifying, and deleting database content when the LINE Campaign Module is enabled.

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 high severity due to the following factors:

• Attack Vector (AV:N): Network-based attack.
• Attack Complexity (AC:L): Low complexity required to exploit.
• Privileges Required (PR:N): No privileges required.
• User Interaction (UI:N): No user interaction required.
• Scope (S:U): Unchanged.
• Confidentiality (C:H): High impact on confidentiality.
• Integrity (I:H): High impact on integrity.
• Availability (A:H): High impact on availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Remote Attack: Attackers can exploit this vulnerability without needing authentication, making it highly accessible.
• FetchXml Injection: By injecting malicious FetchXml commands, attackers can manipulate database queries to read, modify, or delete data.

Exploitation Methods:

• Direct Injection: Attackers can craft HTTP requests with malicious FetchXml commands to exploit the vulnerability.
• Automated Scripts: Attackers may use automated scripts to scan for vulnerable instances of the AIM LINE Marketing Platform and exploit them en masse.
