EUVD-2025-7076

Comprehensive Technical Analysis of EUVD-2025-7076

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2025-7076 affects the eosphoros-ai/db-gpt software, specifically version v0.6.0. The web API endpoint POST /api/v1/editor/sql/run allows the execution of arbitrary SQL queries without any access control. This vulnerability can be exploited to perform Arbitrary File Write using DuckDB SQL, potentially leading to Remote Code Execution (RCE).

Severity Evaluation:

• CVSS Base Score: 9.1
• CVSS Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H

The high base score of 9.1 indicates a critical vulnerability. The CVSS vector breakdown shows that the vulnerability can be exploited over the network (AV:N), requires low complexity (AC:L), does not require any privileges (PR:N) or user interaction (UI:N), and has a high impact on integrity (I:H) and availability (A:H).

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Unauthenticated Access: An attacker can send a crafted POST request to the /api/v1/editor/sql/run endpoint without needing any authentication.
2. SQL Injection: The attacker can inject malicious SQL queries to manipulate the database.
3. Arbitrary File Write: Using DuckDB SQL, the attacker can write arbitrary files to the victim's file system.
4. Remote Code Execution (RCE): By writing executable files or scripts, the attacker can achieve RCE, leading to full system compromise.

Exploitation Methods:

• SQL Injection: Crafting SQL queries to extract data, modify database contents, or execute administrative operations.
• File Write Operations: Using SQL commands to write files to critical system directories, such as writing a malicious script to /tmp and executing it.
• Chaining Exploits: Combining SQL injection with file write capabilities to achieve RCE.

3. Affected Systems and Software Versions

Affected Software:

• eosphoros-ai/db-gpt version v0.6.0

Potentially Affected Systems:

• Any system running the vulnerable version of eosphoros-ai/db-gpt.
• Systems with network access to the vulnerable API endpoint.

4. Recommended Mitigation Strategies

1. Immediate Patching: Upgrade to a patched version of eosphoros-ai/db-gpt as soon as it becomes available.
2. Access Control: Implement proper access control mechanisms to restrict access to the /api/v1/editor/sql/run endpoint.
3. Input Validation: Ensure that all inputs to the SQL query are properly validated and sanitized.
4. Network Segmentation: Isolate the vulnerable system from critical networks to limit the potential impact.
5. Monitoring and Logging: Enhance monitoring and logging to detect and respond to any suspicious activities related to the vulnerable endpoint.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to organizations using eosphoros-ai/db-gpt, particularly those in the European Union. The potential for RCE can lead to data breaches, system compromises, and disruptions in services. Given the critical nature of the vulnerability, it is essential for organizations to prioritize patching and implementing robust security measures to mitigate the risk.

6. Technical Details for Security Professionals

Vulnerability Details:

• Endpoint: POST /api/v1/editor/sql/run
• Exploit Type: Arbitrary SQL Execution leading to Arbitrary File Write and RCE
• Affected Component: SQL query execution mechanism in eosphoros-ai/db-gpt

Detection and Response:

• Detection: Implement Intrusion Detection Systems (IDS) to monitor for unusual SQL query patterns and file write operations.
• Response: Develop an incident response plan that includes isolating affected systems, applying patches, and conducting a thorough investigation to identify the extent of the compromise.

Preventive Measures:

• Code Review: Conduct a thorough code review to identify and fix similar vulnerabilities.
• Security Training: Educate developers and administrators on secure coding practices and the importance of access control.
