CVE-2025-61811 Adobe ColdFusion vulnerability security critical severity Improper Access Control arbitrary code execution CVE database security advisory patch remediation

Summary

CVE-2025-61811 is a critical Improper Access Control vulnerability affecting Adobe ColdFusion versions 2025.4, 2023.16, 2021.22 and earlier. Successful exploitation could allow a high-privileged attacker to bypass security restrictions and execute arbitrary code within the context of the current user, potentially leading to complete system compromise.

Technical Details

CVE-2025-61811 stems from an Improper Access Control flaw within Adobe ColdFusion. The vulnerability allows a high-privileged attacker to circumvent intended security mechanisms designed to restrict access to sensitive functionalities and resources. This circumvention enables the attacker to execute arbitrary code on the affected system. The specific technical details of the vulnerability are not publicly disclosed to prevent further exploitation before patching. However, the nature of Improper Access Control suggests that the attacker is able to manipulate or bypass authentication or authorization checks within the ColdFusion application server. This could involve exploiting weaknesses in session management, privilege escalation pathways, or insecure direct object references. The lack of user interaction required for exploitation significantly increases the risk associated with this vulnerability.

Affected Products and Versions

The following Adobe ColdFusion versions are affected by CVE-2025-61811:

  • Adobe ColdFusion 2025.4
  • Adobe ColdFusion 2023.16
  • Adobe ColdFusion 2021.22 and earlier

Note: All versions prior to the listed versions are also considered vulnerable.

Impact Assessment

Successful exploitation of CVE-2025-61811 can have severe consequences for affected systems and organizations. The ability to execute arbitrary code allows an attacker to:

  • Gain complete control of the ColdFusion server: This includes access to all data, configuration files, and system resources.
  • Compromise sensitive data: Confidential information stored within the ColdFusion application or accessible through it can be stolen or modified.
  • Launch further attacks: The compromised server can be used as a launching point for attacks against other systems on the network.
  • Disrupt services: The attacker can disrupt or completely shut down the ColdFusion application, leading to business downtime and financial losses.
  • Install malware: The attacker can install malware, such as ransomware or keyloggers, on the compromised server.

Remediation

It is crucial to apply the necessary patches as soon as possible to mitigate the risk posed by CVE-2025-61811.

Immediate Actions

  • Apply the Security Patch: Adobe has released security patches to address this vulnerability. Immediately download and apply the appropriate patch for your ColdFusion version from the Adobe Security Bulletin (linked in the References section).
  • Verify Patch Installation: After applying the patch, verify that it has been installed correctly by checking the ColdFusion version number.
  • Monitor System Activity: Closely monitor your ColdFusion servers for any suspicious activity, such as unusual login attempts, unauthorized file access, or unexpected process execution.

Long-term Solutions

  • Keep ColdFusion Up-to-Date: Regularly update your ColdFusion installation with the latest security patches and updates to protect against future vulnerabilities.
  • Implement Strong Access Controls: Enforce strict access controls to limit user privileges and prevent unauthorized access to sensitive resources.
  • Regular Security Audits: Conduct regular security audits of your ColdFusion environment to identify and address potential vulnerabilities.
  • Web Application Firewall (WAF): Implement a Web Application Firewall (WAF) to detect and block malicious traffic targeting your ColdFusion application.
