Comprehensive Technical Analysis of CVE-2023-28437

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2023-28437 CVSS Score: 9.8

The vulnerability in Dataease, an open-source data visualization and analysis tool, involves an incomplete blacklist for SQL injection protection. This flaw allows attackers to bypass the existing SQL injection protections, potentially leading to unauthorized database access, data manipulation, or data exfiltration.

Severity Evaluation:

• CVSS Score: 9.8 (Critical)
• Impact: High
• Exploitability: High

The high CVSS score indicates that this vulnerability poses a significant risk. The lack of a complete blacklist for SQL injection protection can be easily exploited by attackers, making it a critical issue that requires immediate attention.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• SQL Injection: Attackers can craft malicious SQL queries that bypass the incomplete blacklist, allowing them to execute arbitrary SQL commands.
• Data Manipulation: Unauthorized SQL commands can alter, delete, or insert data into the database.
• Data Exfiltration: Attackers can extract sensitive information from the database.

Exploitation Methods:

• Manual Exploitation: Attackers can manually craft SQL injection payloads to exploit the vulnerability.
• Automated Tools: Use of automated SQL injection tools to identify and exploit the vulnerability.

3. Affected Systems and Software Versions

Affected Software:

• Dataease versions prior to 1.18.5

Affected Systems:

• Any system running Dataease versions prior to 1.18.5, including but not limited to:
  • Servers hosting Dataease
  • Cloud environments with Dataease deployments
