EUVD-2025-7088

Comprehensive Technical Analysis of EUVD-2025-7088

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified in the EUVD entry EUVD-2025-7088 pertains to the eosphoros-ai/db-gpt software, specifically in version 0.6.0. The issue resides in the RAG-knowledge endpoint, which allows for arbitrary file write due to the improper handling of absolute paths in a call to os.path.join. This vulnerability can be exploited by setting the doc_file.filename to an absolute path, leading to potential overwriting of system files or the creation of new SSH-key entries.

Severity Evaluation:

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

The high base score indicates a critical vulnerability. The attack vector (AV:N) is network-based, requiring low attack complexity (AC:L) and no privileges (PR:N) or user interaction (UI:N). The impact on integrity (I:H) and availability (A:H) is high, while the confidentiality impact (C:N) is none. The scope (S:U) is unchanged.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Remote Exploitation: An attacker can send a specially crafted request to the RAG-knowledge endpoint with an absolute path in the doc_file.filename parameter.
2. File Overwrite: The attacker can overwrite critical system files, leading to system instability or unauthorized access.
3. SSH Key Injection: The attacker can create new SSH keys, allowing unauthorized access to the server.

Exploitation Methods:

• Payload Crafting: The attacker crafts a payload with an absolute path in the doc_file.filename parameter.
• Network Request: The attacker sends the crafted payload to the vulnerable endpoint via a network request.
• File Manipulation: The attacker manipulates files on the server, potentially overwriting system files or injecting malicious content.

3. Affected Systems and Software Versions

Affected Software:

• eosphoros-ai/db-gpt version 0.6.0

Affected Systems:

• Any server or system running the vulnerable version of eosphoros-ai/db-gpt.

4. Recommended Mitigation Strategies

1. Immediate Patching: Upgrade to a patched version of eosphoros-ai/db-gpt that addresses the vulnerability.
2. Input Validation: Implement strict input validation to ensure that only relative paths are accepted for file operations.
3. Access Controls: Restrict access to the RAG-knowledge endpoint to trusted users and systems.
4. Monitoring and Logging: Enhance monitoring and logging to detect and respond to suspicious activities related to the RAG-knowledge endpoint.
5. Regular Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate similar issues.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to organizations using eosphoros-ai/db-gpt, particularly those in critical sectors such as finance, healthcare, and government. The potential for unauthorized access and system compromise can lead to data breaches, financial loss, and disruption of services. The high severity of this vulnerability underscores the need for robust cybersecurity measures and continuous monitoring within the European cybersecurity landscape.
