MITRE ATT&CK
2 techniques across 1 tactic: Execution The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | No special conditions - remote unauthenticated exploitation against network-reachable Adobe ColdFusion 2023 and 2025 instances, per the CVSS vector AV:N/AC:L/PR:N/UI:N and the description's statement that exploitation does not require user interaction. The practical limiting factor is network reachability: the ColdFusion service (or the specific vulnerable endpoint) must be accessible to the attacker, so instances confined to trusted internal networks or behind strict access controls face materially lower risk than internet-exposed deployments. No non-default feature toggle or configuration setting is named in the available data as a prerequisite. |
| Impact | This is a top-priority vulnerability with essentially every risk signal maximized: the CVSS 3.1 vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H yields a perfect 10.0, indicating network-reachable, low-complexity, unauthenticated exploitation with full confidentiality, integrity, and availability impact and a scope change onto the host. No EPSS score, KEV listing, or SSVC decision data was supplied, so probabilistic and active-exploitation signals cannot be independently corroborated here - the urgency rests on the vector and product history rather than confirmed in-the-wild activity. Given ColdFusion's long track record of being rapidly weaponized after disclosure, even a mid-sized municipal IT team in bytom should treat this as urgent and patch before exploit code circulates. In short, this is a genuine emergency-patch item, not a high-CVSS-but-low-real-risk case, though defenders should verify EPSS and KEV status directly as those inputs were absent. |
| Exploit ScenarioDerived | An attacker locates an internet-exposed ColdFusion 2023 or 2025 instance and sends a crafted HTTP request containing shell metacharacters to the vulnerable endpoint, breaking out into an OS command that runs with the privileges of the ColdFusion service. Because no authentication or user interaction is required and complexity is low, the attacker can immediately execute commands to drop a web shell, harvest credentials, or pivot into the host. No public exploit identified at time of analysis, but the low-complexity, unauthenticated nature makes reliable exploitation straightforward once a payload is developed. |

Alert meAnalysisAIv1 – Aug 11, 2026
OS command injection in Adobe ColdFusion 2023 and 2025 enables remote, unauthenticated attackers to execute arbitrary operating-system commands in the context of the ColdFusion service account. Rated CVSS 10.0 with a scope change (S:C), this flaw stems from improper neutralization of special elements passed into an OS command and requires no user interaction. No public exploit identified at time of analysis, but ColdFusion's history as an attacker-favored target makes rapid patching essential.
RemediationAI
Apply the fixes described in Adobe security bulletin APSB26-90 (https://helpx.adobe.com/security/products/coldfusion/apsb26-90.html) for both ColdFusion 2023 and ColdFusion 2025; the input data does not specify an exact fixed build number, so consult the advisory for the precise patched version and install it promptly (Patch available per vendor advisory). Until patched, reduce exposure by restricting network access to the ColdFusion Administrator and any affected endpoints via firewall/IP allowlisting, placing the server behind a WAF with rules to block OS command metacharacters, running the ColdFusion service under a least-privileged account to limit the impact of the scope change, and applying Adobe's lockdown guide - noting that aggressive WAF rules or endpoint restrictions may break legitimate application functionality and should be tested before broad rollout.

Technical ContextAI · show details
Adobe ColdFusion is a commercial rapid web-application platform built on the JVM that renders CFML templates and exposes numerous administrative and runtime services. The root cause is classified as CWE-78 (Improper Neutralization of Special Elements used in an OS Command), meaning attacker-influenced input reaches a shell or process-execution call without adequate sanitization, allowing command metacharacters to break out of the intended argument and launch new OS processes. The CPE data pins the affected software to cpe:2.3:a:adobe:coldfusion_2025 and cpe:2.3:a:adobe:coldfusion_2023, and the scope-change (S:C) in the CVSS vector indicates the exploited component (the ColdFusion application) can affect resources beyond its own security authority, i.e. the underlying host OS.

DescriptionCVE.org
ColdFusion is affected by an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability that could result in arbitrary code execution in the context of the current user. An attacker could exploit this vulnerability to execute arbitrary code. Exploitation of this issue does not require user interaction. Scope is changed.
Executive ViewAI
Adobe ColdFusion 2023 and 2025 contain a critical remote command injection vulnerability (CVSS 10.0) allowing unauthenticated attackers to execute arbitrary operating-system commands within the ColdFusion service account, potentially compromising entire application servers and all dependent systems. Organizations running affected versions face immediate risk of complete infrastructure compromise with no available vendor patch. Given ColdFusion's history as a high-value target, this requires urgent mitigation and continuous monitoring for patch availability.
No vendor-released patch identified at time of analysis. Interim mitigations: (1) Network segmentation-restrict ColdFusion instance access to trusted internal networks and required dependencies only; (2) Web Application Firewall-deploy signatures to detect OS command injection payloads and shell metacharacters in requests; (3) Service account hardening-run ColdFusion under least-privilege account with no shell access or sudo permissions; (4) Enhanced monitoring-implement behavioral detection on ColdFusion process creation and system command execution, alerting on anomalies; (5) Access controls-require authentication/VPN for all ColdFusion access; consider temporary disabling of non-critical ColdFusion services pending patch release.

Attack Technique
OS command injection occurs when an application passes unsanitized user input directly into system shell commands.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
