CVE-2025-30281: Adobe ColdFusion RCE Vulnerability

CVE-2025-30281 Overview

CVE-2025-30281 is an Improper Access Control vulnerability affecting Adobe ColdFusion, a widely-deployed web application server platform. The vulnerability allows high-privileged attackers to bypass authorization controls and achieve arbitrary code execution on affected systems. This flaw enables unauthorized access to or modification of sensitive data without requiring any user interaction, and critically, the scope of impact extends beyond the vulnerable component itself.

Critical Impact

This vulnerability enables arbitrary code execution through improper access control, allowing attackers with high privileges to access or modify sensitive data across security boundaries without user interaction.

Affected Products

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

Discovery Timeline

• April 8, 2025 - CVE-2025-30281 published to NVD
• July 15, 2025 - Last updated in NVD database

Technical Details for CVE-2025-30281

Vulnerability Analysis

This vulnerability is classified under CWE-284 (Improper Access Control), indicating a fundamental flaw in how ColdFusion validates and enforces access permissions. The improper access control mechanism allows authenticated users with elevated privileges to bypass security boundaries that should restrict their access.

The "scope changed" characteristic indicates that successful exploitation impacts resources beyond the vulnerable component's security scope. This means an attacker who compromises ColdFusion through this vulnerability could potentially affect other systems, services, or data stores that the ColdFusion server has access to, amplifying the overall impact significantly.

Root Cause

The root cause stems from inadequate authorization verification within ColdFusion's access control implementation. The application fails to properly validate whether privileged users are authorized to perform specific actions or access certain resources, allowing them to exceed their intended permissions. This type of flaw typically occurs when authorization checks are missing, incomplete, or can be circumvented through specific request patterns.

Attack Vector

The vulnerability is exploitable remotely over the network. An attacker with high-privilege access to the ColdFusion server can craft requests that bypass access control mechanisms. The attack does not require any user interaction, meaning it can be executed entirely through direct network requests to the vulnerable ColdFusion instance.

The exploitation path involves:

1. Authenticating to the ColdFusion server with a high-privileged account
2. Crafting requests that exploit the improper access control mechanism
3. Accessing or modifying resources that should be protected beyond the attacker's authorization level
4. Potentially achieving arbitrary code execution on the underlying system

Detection Methods for CVE-2025-30281

Indicators of Compromise

• Unusual administrative activity or access patterns on ColdFusion servers from privileged accounts
• Evidence of unauthorized file modifications or data access in ColdFusion application directories
• Anomalous outbound network connections originating from the ColdFusion server process
• Unexpected process execution spawned by the ColdFusion service

Detection Strategies

• Monitor ColdFusion access logs for suspicious API calls or administrative actions that exceed expected user behavior patterns
• Implement file integrity monitoring on ColdFusion installation directories and web roots to detect unauthorized modifications
• Deploy network-based intrusion detection rules to identify exploitation attempts targeting ColdFusion access control mechanisms
• Enable detailed audit logging for all administrative actions within ColdFusion Administrator

Monitoring Recommendations

• Configure centralized logging for all ColdFusion server instances and establish baseline behavioral patterns
• Implement real-time alerting for administrative changes, code deployments, or configuration modifications outside approved change windows
• Monitor for process creation events from coldfusion.exe or Java processes associated with ColdFusion that spawn unexpected child processes

How to Mitigate CVE-2025-30281

Immediate Actions Required

• Apply Adobe security updates immediately by upgrading to ColdFusion 2025.1, 2023 Update 13, or 2021 Update 19
• Audit all high-privileged ColdFusion accounts and remove unnecessary administrative access
• Review recent administrative activity logs for signs of exploitation
• Implement network segmentation to restrict access to ColdFusion administrative interfaces

Patch Information

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

• ColdFusion 2025: Update to version 2025.1 or later
• ColdFusion 2023: Apply Update 13 or later
• ColdFusion 2021: Apply Update 19 or later

Workarounds

• Restrict network access to ColdFusion servers using firewall rules, limiting exposure to trusted IP ranges only
• Disable or restrict ColdFusion Administrator access from external networks
• Implement additional authentication layers (VPN, multi-factor authentication) for administrative access to ColdFusion servers
• Apply principle of least privilege to all ColdFusion administrative accounts, reducing the number of high-privileged users

# Example: Restrict ColdFusion Administrator access via IP whitelist
# Add to web server configuration (Apache example)
<Location /CFIDE/administrator>
    Require ip 10.0.0.0/8
    Require ip 192.168.1.0/24
</Location>
