Comprehensive Technical Analysis of EUVD-2023-30377

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The EUVD entry EUVD-2023-30377 describes an unauthenticated SQL injection vulnerability in the GetExcursionDetails method of IDAttend’s IDWeb application, versions 3.1.052 and earlier. This vulnerability allows unauthenticated attackers to extract or modify all data within the application.

Severity Evaluation: The vulnerability has a CVSS (Common Vulnerability Scoring System) 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)
• 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): High (H)
• Availability (A): High (H)

This high score reflects the severe impact on confidentiality, integrity, and availability, combined with the ease of exploitation.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: The vulnerability can be exploited without any authentication, making it accessible to any attacker with network access.
• SQL Injection: The attacker can inject malicious SQL queries through the GetExcursionDetails method, leading to unauthorized data extraction or modification.

Exploitation Methods:

• Data Exfiltration: Attackers can craft SQL queries to extract sensitive information from the database.
• Data Manipulation: Attackers can modify database entries, leading to data integrity issues.
• Denial of Service (DoS): Attackers can execute SQL commands that disrupt the normal operation of the database, causing service outages.

3. Affected Systems and Software Versions

Affected Software:

• Product: IDWeb
• Vendor: IDAttend Pty Ltd
• Versions: 3.1.052 and earlier

All systems running the specified versions of IDWeb are vulnerable to this SQL injection attack.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Patching: Upgrade to a version of IDWeb that addresses this vulnerability. If a patch is not available, consider disabling the GetExcursionDetails method until a fix is released.
• Input Validation: Implement strict input validation and sanitization for all user inputs to prevent SQL injection.
• Web Application Firewall (WAF): Deploy a WAF to detect and block SQL injection attempts.
