Comprehensive Technical Analysis of EUVD-2025-5588

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2025-5588, also known as CVE-2024-55160, is a SQL injection vulnerability affecting GFast versions between v2 and v3.2. The vulnerability is located in the OrderBy parameter at the /system/operLog/list endpoint. 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 is exploitable over the network.
• Attack Complexity (AC): Low (L) - The attack requires minimal skill and resources.
• Privileges Required (PR): None (N) - No special privileges are needed to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required.
• Scope (S): Unchanged (U) - The vulnerability does not affect other security scopes.
• Confidentiality (C): High (H) - There is a high impact on the confidentiality of the data.
• Integrity (I): High (H) - There is a high impact on the integrity of the data.
• Availability (A): High (H) - There is a high impact on the availability of the system.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector is through the OrderBy parameter in the /system/operLog/list endpoint. An attacker can inject malicious SQL code into this parameter to manipulate the database queries. Potential exploitation methods include:

• Data Exfiltration: Extracting sensitive information from the database.
• Data Manipulation: Altering database records to compromise data integrity.
• Denial of Service (DoS): Executing SQL commands that disrupt the normal operation of the database.
• Privilege Escalation: Gaining higher privileges within the database or application.

3. Affected Systems and Software Versions

The vulnerability affects GFast versions between v2 and v3.2. Specifically, the issue is present in the following files:

• api/v1/system/sys_oper_log.go at line 35
• internal/app/system/logic/sysOperLog/sys_oper_log.go at line 121

Users of GFast within this version range are at risk and should take immediate action to mitigate the vulnerability.

4. Recommended Mitigation Strategies

To mitigate the risk associated with this vulnerability, the following steps are recommended:

• Patch Management: Upgrade to a patched version of GFast that addresses this vulnerability.
• Input Validation: Implement robust input validation and sanitization for all user-supplied data, especially for parameters used in SQL queries.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection.
• Web Application Firewalls (WAF): Deploy WAFs to detect and block SQL injection attempts.
• Regular Audits: Conduct regular security audits and code reviews to identify and fix similar vulnerabilities.

5. Impact on European Cybersecurity Landscape

The high severity of this vulnerability poses a significant risk to organizations using GFast within the affected version range. Given the critical nature of the vulnerability, it could lead to widespread data breaches, financial losses, and reputational damage. European organizations must prioritize patching and implementing robust security measures to protect against such threats.
