Unauthenticated attackers can achieve full system compromise via critical Adobe ColdFusion flaws
馃毃 Critical flaw in Adobe ColdFusion 2025 enables full system compromise. Attackers can execute arbitrary commands without any user interaction or authentication. Patch your ColdFusion instances immediately to prevent remote exploitation.
Summary
Adobe has released security updates to address a critical vulnerability in ColdFusion 2025. The flaw, tracked as CVE-2026-48362, is classified as an OS Command Injection vulnerability. This allows a remote attacker to execute arbitrary code within the context of the current user running the ColdFusion service.
The vulnerability stems from improper neutralization of special elements used in operating system commands. Because the exploit does not require any user interaction or valid credentials, it presents a high risk for unauthenticated remote attackers targeting exposed ColdFusion environments.
Technical details
The core issue lies in how ColdFusion 2025 processes specific inputs before passing them to the underlying operating system. An attacker can supply specially crafted input that bypasses existing filters, allowing them to inject their own commands into the execution flow.
According to the official advisory, this vulnerability results in a change of scope. This means an exploit targeting the ColdFusion application could potentially impact the broader underlying system or environment beyond the application itself.
The technical severity is reflected in its CVSS score of 10.0. The attack vector is network-based, requiring no local access or user involvement to trigger the malicious command execution.
Affected products and fixed versions
This vulnerability specifically impacts Adobe ColdsFusion 2025. Organizations running this version must prioritize updates to mitigate the risk of remote code execution.
| Product | Vulnerability | Severity | Status |
|---|---|---|---|
| Adobe ColdFusion 2025 | CVE-2026-48362 | Critical (10.0) | Patch Available |
Why this matters for defenders
Command injection vulnerabilities are high-priority targets because they provide a direct path to system takeover. In the case of ColdFusion, an attacker who successfully exploits this flaw gains the ability to run commands with the same privileges as the user running the ColdFusion service.
If the service is running with elevated or administrative privileges, the impact on the host machine and the wider network could be catastrophic. Attackers can use this access to install malware, exfiltrate sensitive data, or move laterally through the infrastructure.
Because no authentication is required to trigger the flaw, any internet-facing ColdFusion 2025 instance is a potential target for automated scanning and exploitation attempts.
Defender guidance
The primary defense against this vulnerability is applying the official Adobe security patches immediately. Ensure all ColdFusion 2025 installations are updated to the latest version provided by Adobe.
While waiting for patch deployment, defenders should:
- Monitor system logs for unusual child processes spawned by the ColdFusion service.
- Inspect incoming web requests for suspicious characters or command sequences often used in injection attacks (such as semicolons, pipes, or backticks).
- Implement strict network segmentation to limit the ability of a compromised application server to communicate with other internal assets.
