EUVD-2025-6905

Comprehensive Technical Analysis of EUVD-2025-6905

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-6905 is a path traversal issue in the modelscope/agentscope application, specifically affecting the /delete-workflow endpoint. This vulnerability allows an attacker to delete arbitrary files from the filesystem due to improper input validation. The severity of this vulnerability is rated with a CVSS Base Score of 9.1, which is considered critical. The CVSS vector CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H indicates the following:

• Attack Vector (AV): Network (N) - The vulnerability is exploitable over the network.
• Attack Complexity (AC): Low (L) - The attack requires minimal skill or 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 change the security scope.
• Confidentiality (C): None (N) - There is no impact on confidentiality.
• Integrity (I): High (H) - There is a high impact on integrity.
• Availability (A): High (H) - There is a high impact on availability.

2. Potential Attack Vectors and Exploitation Methods

An attacker can exploit this vulnerability by crafting a malicious request to the /delete-workflow endpoint with a specially crafted file path. This path can traverse directories and target files outside the intended directory, leading to the deletion of critical system files, configuration files, or other sensitive data.

Example Exploitation Method:

• An attacker sends a request to /delete-workflow with a payload like ../../../../etc/passwd, which could delete the /etc/passwd file on a Unix-based system.

3. Affected Systems and Software Versions

The vulnerability affects all versions of the modelscope/agentscope application. The ENISA ID Product entry specifies that the product version is "unspecified ≤latest," indicating that all versions up to the latest release are vulnerable.

4. Recommended Mitigation Strategies

1. Immediate Patching: Apply the patch provided in the GitHub pull request (#459) and commit (7d285e862f86fa1d96ed04c4cd40a5f1b8f9189a) to fix the vulnerability.
2. Input Validation: Ensure that all input is properly validated and sanitized to prevent path traversal attacks.
3. Least Privilege Principle: Run the application with the least privileges necessary to minimize the impact of a successful attack.
4. File System Permissions: Restrict file system permissions to prevent unauthorized access to critical files.
5. Monitoring and Logging: Implement robust monitoring and logging to detect and respond to suspicious activities.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to organizations using the modelscope/agentscope application, particularly those in critical sectors such as finance, healthcare, and government. The potential for data loss and system disruption could lead to severe operational and financial impacts. Given the critical nature of the vulnerability, it is essential for European organizations to prioritize patching and implementing robust security measures to mitigate the risk.
