CVE-2025-56267

Comprehensive Technical Analysis of CVE-2025-56267

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-56267 CVSS Score: 9.8

The CVSS score of 9.8 indicates that this vulnerability is critical. The high score is likely due to the potential for arbitrary code execution, which can lead to complete system compromise. The vulnerability involves a CSV injection in the /id_profiles endpoint of Avigilon ACM v7.10.0.20, allowing attackers to execute arbitrary code by supplying a crafted Excel file.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Phishing: An attacker could send a crafted Excel file to a user who has access to the Avigilon ACM system, enticing them to upload it to the /id_profiles endpoint.
• Internal Threats: An insider with access to the system could upload a malicious Excel file directly.
• Supply Chain Attacks: An attacker could compromise a legitimate Excel file used in the system and inject malicious code.

Exploitation Methods:

• CSV Injection: The attacker crafts an Excel file with malicious formulas or scripts that, when processed by the system, execute arbitrary code.
• Command Injection: If the system processes the CSV data and executes commands based on the input, an attacker could inject commands to gain control over the system.

3. Affected Systems and Software Versions

Affected Software:

• Avigilon ACM v7.10.0.20

Affected Systems:

• Any system running Avigilon ACM v7.10.0.20 with the /id_profiles endpoint exposed and accessible.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patch Management: Apply the latest patches and updates provided by Avigilon to mitigate the vulnerability.
• Input Validation: Implement strict input validation to ensure that only legitimate data is processed by the /id_profiles endpoint.
• Access Control: Restrict access to the /id_profiles endpoint to trusted users and systems only.

Long-Term Strategies:

• Security Awareness Training: Educate users on the risks of uploading untrusted files and the importance of verifying file sources.
• Regular Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate similar vulnerabilities.
• Network Segmentation: Segment the network to limit the impact of a potential compromise.

5. Impact on Cybersecurity Landscape

The discovery of CVE-2025-56267 highlights the ongoing risk of CSV injection vulnerabilities, particularly in systems that process user-supplied files. This vulnerability underscores the importance of robust input validation and secure coding practices. Organizations must remain vigilant in updating and patching their systems to protect against such critical vulnerabilities.

6. Technical Details for Security Professionals

Vulnerability Details:

• The vulnerability exists in the /id_profiles endpoint of Avigilon ACM v7.10.0.20.
• The endpoint processes Excel files without proper validation, allowing for CSV injection.
• An attacker can craft an Excel file with malicious formulas or scripts that execute arbitrary code when processed.

Exploitation Steps:

1. Crafting the Malicious File: Create an Excel file with embedded malicious formulas or scripts.
2. Uploading the File: Upload the crafted file to the /id_profiles endpoint.
3. Code Execution: The system processes the file, leading to arbitrary code execution.

Detection and Monitoring:

• Log Analysis: Monitor system logs for unusual activity related to the /id_profiles endpoint.
• File Integrity Monitoring: Implement file integrity monitoring to detect unauthorized changes to critical files.
• Intrusion Detection Systems (IDS): Deploy IDS to detect and alert on suspicious activities related to file uploads and processing.
