EUVD-2025-6194

Comprehensive Technical Analysis of EUVD-2025-6194

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-6194 pertains to GMOD Apollo, a web-based genome annotation tool. The issue arises when uploading organism or sequence data via the web interface. The software unzips and inspects the files without checking for path traversal in supported archive types. This oversight can lead to significant security risks.

Severity Evaluation:

• Base Score: 9.3
• Base Score Version: 4.0
• Base Score Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N

The high base score of 9.3 indicates a critical vulnerability. The CVSS vector breakdown reveals:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Authentication (AT): None (N)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Confidentiality Impact (VC): High (H)
• Integrity Impact (VI): High (H)
• Availability Impact (VA): High (H)
• Scope Change (SC): None (N)
• Scope Impact (SI): None (N)
• Scope Availability (SA): None (N)

This vulnerability can be exploited remotely with low complexity, requiring no authentication or user interaction, and can result in high impacts on confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Path Traversal: An attacker can craft a malicious archive file that, when unzipped, exploits the path traversal vulnerability to write files outside the intended directory.
• Arbitrary File Write: This can lead to arbitrary file writes, potentially overwriting critical system files or injecting malicious code.

Exploitation Methods:

• Malicious Archive Upload: An attacker can upload a specially crafted archive file containing path traversal sequences.
• Remote Code Execution: By placing malicious scripts or executables in strategic locations, an attacker can achieve remote code execution.
• Data Exfiltration: Sensitive data can be exfiltrated by overwriting configuration files or injecting scripts that send data to an attacker-controlled server.

3. Affected Systems and Software Versions

Affected Software:

• Product: GMOD Apollo
• Versions: All versions prior to 2.8.0

Affected Systems:

• Any system running the vulnerable versions of GMOD Apollo, particularly those with web interfaces exposed to the internet.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Upgrade: Upgrade to GMOD Apollo version 2.8.0 or later, which includes a fix for this vulnerability.
• Temporary Workaround: Disable the file upload feature until the system can be updated.

Long-Term Mitigation:

• Input Validation: Implement robust input validation and sanitization for uploaded files.
• Access Controls: Enforce strict access controls and authentication mechanisms for the web interface.
• Regular Audits: Conduct regular security audits and vulnerability assessments.
• Network Segmentation: Segment the network to limit the exposure of critical systems.

5. Impact on European Cybersecurity Landscape

The vulnerability in GMOD Apollo poses a significant risk to European organizations, particularly those in the biomedical and research sectors that rely on genome annotation tools. The potential for data breaches, unauthorized access, and system compromise can have far-reaching implications, including:

• Data Integrity: Compromise of sensitive genomic data.
• Operational Disruption: Disruption of research and operational activities.
• Reputation Damage: Loss of trust and reputation for affected organizations.

6. Technical Details for Security Professionals

Technical Overview:

• Vulnerability Type: Path Traversal
• Exploit Mechanism: Unzipping and inspecting files without proper path traversal checks.
• Impact: Arbitrary file writes, potential remote code execution, and data exfiltration.

Detection and Monitoring:

• Log Analysis: Monitor logs for unusual file upload activities and unauthorized file writes.
• Intrusion Detection Systems (IDS): Deploy IDS to detect and alert on suspicious network activities.
• File Integrity Monitoring: Implement file integrity monitoring to detect unauthorized changes to critical files.

Response and Recovery:

• Incident Response Plan: Develop and maintain an incident response plan tailored to handle path traversal vulnerabilities.
• Backup and Restore: Ensure regular backups and test restore procedures to recover from potential data loss or corruption.

Conclusion: The vulnerability in GMOD Apollo, as described in EUVD-2025-6194, is critical and requires immediate attention. Organizations should prioritize upgrading to the patched version and implementing robust security measures to mitigate the risk. Continuous monitoring and proactive security practices are essential to safeguard against such vulnerabilities in the future.
