CVE-2025-30282: Adobe ColdFusion RCE Vulnerability

CVE-2025-30282 Overview

CVE-2025-30282 is an Improper Authentication vulnerability affecting Adobe ColdFusion that could allow an attacker to bypass authentication mechanisms and execute arbitrary code in the context of the current user. This authentication bypass flaw enables a high-privileged attacker to execute malicious code without requiring user interaction, with the scope of the vulnerability extending beyond the vulnerable component itself.

Critical Impact

This vulnerability allows authentication bypass leading to arbitrary code execution, potentially compromising ColdFusion servers and underlying infrastructure. The changed scope indicates impacts beyond the vulnerable component.

Affected Products

• Adobe ColdFusion 2025.0 and earlier
• Adobe ColdFusion 2023.12 and earlier (including all Update 1 through Update 12)
• Adobe ColdFusion 2021.18 and earlier (including all Update 1 through Update 18)

Discovery Timeline

• April 8, 2025 - CVE-2025-30282 published to NVD

Technical Details for CVE-2025-30282

Vulnerability Analysis

This vulnerability is classified under CWE-287 (Improper Authentication), which occurs when software does not properly verify that a user has been authenticated or correctly identify the user. In the context of Adobe ColdFusion, this flaw allows attackers with high privileges to bypass authentication mechanisms that should prevent unauthorized code execution.

The vulnerability is network-accessible, meaning it can be exploited remotely without requiring physical access to the target system. Once authentication is bypassed, the attacker can execute arbitrary code within the security context of the current user, potentially leading to complete system compromise. The changed scope characteristic indicates that the vulnerability can affect resources beyond its security scope, meaning compromise of the ColdFusion application could impact the underlying operating system or other connected services.

Root Cause

The root cause of CVE-2025-30282 lies in improper authentication handling within Adobe ColdFusion. The application fails to adequately verify user credentials or authentication state before granting access to privileged functionality. This authentication bypass allows attackers to circumvent security controls designed to restrict access to sensitive operations, ultimately enabling code execution capabilities that should only be available to authenticated and authorized users.

Attack Vector

The attack vector for CVE-2025-30282 is network-based, requiring no user interaction for successful exploitation. An attacker with high-privileged access can leverage this vulnerability remotely to:

1. Send specially crafted requests to the ColdFusion server
2. Bypass authentication verification mechanisms
3. Execute arbitrary code in the context of the current user
4. Potentially escalate access to impact resources beyond the ColdFusion application

The exploitation does not require any form of user interaction such as clicking links or opening files, making it particularly dangerous in automated attack scenarios. Technical details for constructing exploit payloads should be referenced from the Adobe ColdFusion Security Advisory.

Detection Methods for CVE-2025-30282

Indicators of Compromise

• Unusual authentication attempts or unexpected session creation in ColdFusion logs
• Anomalous code execution or process spawning from the ColdFusion server process
• Unexpected network connections originating from the ColdFusion application server
• Modified or newly created files in ColdFusion installation directories

Detection Strategies

• Implement web application firewall (WAF) rules to detect suspicious requests targeting ColdFusion endpoints
• Monitor ColdFusion access logs for authentication anomalies and repeated failed or bypassed authentication events
• Deploy endpoint detection and response (EDR) solutions to identify unexpected code execution from ColdFusion processes
• Utilize network intrusion detection systems (NIDS) to monitor for exploitation traffic patterns

Monitoring Recommendations

• Enable verbose logging in ColdFusion Administrator for authentication events
• Configure alerts for any code execution or command spawning from ColdFusion service accounts
• Monitor file integrity for ColdFusion configuration and application files
• Implement real-time log analysis to correlate authentication events with subsequent system activities

How to Mitigate CVE-2025-30282

Immediate Actions Required

• Apply the latest Adobe ColdFusion security updates as specified in Adobe Security Bulletin APSB25-15
• Restrict network access to ColdFusion administrative interfaces to trusted IP ranges only
• Review and audit high-privileged accounts with access to ColdFusion administration
• Implement additional authentication controls such as multi-factor authentication where possible

Patch Information

Adobe has released security updates to address this vulnerability as detailed in Adobe Security Bulletin APSB25-15. Organizations should update to the following versions:

• ColdFusion 2025: Update to a version newer than 2025.0
• ColdFusion 2023: Update to a version newer than Update 12
• ColdFusion 2021: Update to a version newer than Update 18

Administrators should consult the Adobe security advisory for specific patch version numbers and installation instructions.

Workarounds

• Restrict access to ColdFusion Administrator and other sensitive endpoints using firewall rules or network segmentation
• Implement strong network-level access controls to limit exposure of ColdFusion services
• Consider disabling non-essential ColdFusion features and endpoints until patches can be applied
• Deploy a web application firewall with rules specifically designed to detect authentication bypass attempts

# Example: Restrict ColdFusion Admin access via iptables
iptables -A INPUT -p tcp --dport 8500 -s 192.168.1.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 8500 -j DROP

# Example: Verify ColdFusion version
cat /opt/coldfusion/cfusion/lib/version.properties
