Horizon Alert
Summary of the vulnerability and why it matters
A critical vulnerability has been identified in Adobe ColdFusion that could allow unauthorized code execution without user interaction. This issue affects various versions of the ColdFusion software, which is used to build and deploy web applications and websites. The potential for arbitrary code execution on the server presents a significant risk if the software is exposed externally.
- Code can be run remotely on ColdFusion servers.
- Business risk is confirmed if ColdFusion is internet-facing.
- Confirm relevant systems and assess potential exposure.
Attack Path
How an attacker could exploit the issue
An attacker can exploit this vulnerability by sending specially crafted input over the network to a vulnerable Adobe ColdFusion server. This input targets an improper input validation flaw, allowing the attacker to execute arbitrary code in the context of the current user, even without requiring any interaction from the user. The scope of the vulnerability changes, potentially impacting a broader range of system functions.
- Entry Condition: Unauthenticated network access.
- Trigger Point: Sending crafted input to the server.
- Resulting Risk: Arbitrary code execution.
Live Threat
Current exploitation, exposure, and threat context
This Improper Input Validation vulnerability in Adobe ColdFusion could allow an unauthenticated attacker to execute arbitrary code on the server. This could occur when the system processes specific, malformed inputs, leading to a compromise of the server's current user context.
- Server-side code execution.
- Malicious input processed by the server.
- System control and data access.
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
Adobe ColdFusion is the affected technology, making application owners and infrastructure teams responsible for addressing this vulnerability. The first practical step is to identify all instances of ColdFusion, determine their exposure and criticality, and then locate the accountable owner to plan remediation.
- Application owners are responsible.
- Verify ColdFusion instance exposure and criticality.
- Plan remediation based on identified risk.
