EUVD-2024-27177

Comprehensive Technical Analysis of EUVD-2024-27177

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified in qdrant/qdrant (EUVD-2024-27177) is a path traversal and arbitrary file upload vulnerability. This vulnerability allows attackers to upload and overwrite any file on the filesystem, potentially leading to remote code execution (RCE). The severity of this vulnerability is rated with a CVSS Base Score of 9.8, which is considered critical. The CVSS vector CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/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 complexity.
• Privileges Required (PR): None (N) - No privileges are required 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): High (H) - The vulnerability has a high impact on confidentiality.
• Integrity (I): High (H) - The vulnerability has a high impact on integrity.
• Availability (A): High (H) - The vulnerability has a high impact on availability.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector involves exploiting the /collections/{COLLECTION}/snapshots/upload endpoint by manipulating the snapshot parameter. Attackers can perform the following actions:

• Path Traversal: By manipulating the file path in the snapshot parameter, attackers can traverse directories and access files outside the intended directory.
• Arbitrary File Upload: Attackers can upload malicious files to arbitrary locations on the filesystem.
• Remote Code Execution (RCE): By uploading executable files or scripts, attackers can execute arbitrary code on the server, leading to complete system compromise.

3. Affected Systems and Software Versions

The vulnerability affects qdrant/qdrant versions prior to 1.8.0. Specifically:

• Product: qdrant/qdrant
• Affected Versions: Unspecified versions <1.8.0

4. Recommended Mitigation Strategies

To mitigate this vulnerability, the following steps are recommended:

• Update Software: Upgrade to qdrant/qdrant version 1.8.0 or later, which includes the fix for this vulnerability.
• Input Validation: Implement strict input validation for the snapshot parameter to prevent path traversal attacks.
• Access Controls: Restrict access to the /collections/{COLLECTION}/snapshots/upload endpoint to authorized users only.
• File Upload Restrictions: Implement restrictions on the types of files that can be uploaded and the locations where they can be stored.
• Monitoring and Logging: Enhance monitoring and logging to detect and respond to suspicious activities related to file uploads and path traversal attempts.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to organizations using qdrant/qdrant, particularly those in critical sectors such as finance, healthcare, and government. The potential for RCE can lead to data breaches, unauthorized access, and system downtime, impacting the confidentiality, integrity, and availability of critical systems. The high EPSS score of 11 indicates a high likelihood of exploitation, making it a priority for immediate remediation.

6. Technical Details for Security Professionals
