Does your ColdFusion server face critical code injection risk?
A critical code injection flaw in Adobe ColdFusion allows attackers to run arbitrary code without user interaction across multiple versions.
Key points
- The vulnerability is rated CVSS 10.0 CRITICAL by the National Vulnerability Database.
- Exploitation does not require any user interaction, enabling direct attacks.
- Adobe ColdFusion 2023 and 2025 versions up to specific updates are affected.
Adobe ColdFusion contains a critical security flaw that permits arbitrary code execution. The issue stems from improper control over code generation, classified as CWE-94. Attackers can inject and execute arbitrary code within the context of the current user. This vulnerability affects widely used enterprise application servers, posing significant operational risks to organizations relying on these platforms.
Root cause
The National Vulnerability Database identifies the core issue as a code injection vulnerability. The system fails to properly control the generation of code, allowing malicious input to be processed as executable instructions. This weakness enables an attacker to bypass standard security boundaries. The flaw allows for arbitrary code execution, meaning the attacker can run commands the application user has permission to execute.
Attack path
Exploitation of this vulnerability does not require user interaction. An attacker can trigger the flaw by sending crafted requests to the vulnerable server. Because no user action is needed, the issue can be exploited directly. The scope change in the CVSS scoring reflects the severity of this access vector, allowing execution in the context of the current user.
Affected versions
- Adobe ColdFusion 2025 versions up to and including 2025.0.13
- Adobe ColdFusion 2023 versions up to and including 2023.0.25
Organizations running these specific versions are directly exposed. Any deployment using these builds requires immediate attention. Versions newer than those listed are not indicated as affected in the current advisory.
Mitigation
- Verify the exact version of Adobe ColdFusion installed on all servers.
- Compare installed versions against the affected list provided by Adobe.
- Apply vendor-provided updates immediately if a version is listed as affected.
- Monitor server logs for unusual activity or unauthorized code execution attempts.
What it means for organisations
IT leaders must immediately inventory all ColdFusion deployments to identify exposure. Security teams should assess whether these servers are accessible from untrusted networks. Procurement and vendor management groups need to confirm if third-party suppliers use affected versions. Internal communications should alert development teams to review integration points. Risk managers must evaluate the potential impact of arbitrary code execution on data integrity and availability. Prompt action is essential to prevent unauthorized access.
What to do and how to stay safe: Adobe
- Audit your network to locate all instances of Adobe ColdFusion.
- Check version numbers against the affected list in the NVD record.
- Restrict network access to ColdFusion servers to trusted IP addresses only.
- Wait for official vendor patches before applying unverified workarounds.
