Analysis

AI-generated

Technical impact

ColdFusion is affected by an improper input validation flaw that can lead to arbitrary code execution in the context of the current user. The vulnerability is classified as CWE-20, and the scope change indicates that an attacker may gain privileges beyond the originally intended application scope, potentially accessing additional internal resources.

Affected Systems

Adobe ColdFusion 2023 and Adobe ColdFusion 2025 are listed as affected. The advisory does not enumerate specific sub‑versions or release candidates, so administrators should verify whether their deployed release is covered by the published fix.

Risk and Exploitability

The CVSS score of 9.6 places this vulnerability in the critical range, and the EPSS score of <1% indicates a very low likelihood of exploitation. The flaw is not listed in the CISA KEV catalog. While the exact attack vector is not specified in the description, it is inferred that a remote actor can trigger the flaw by sending malicious input to a vulnerable ColdFusion endpoint, especially since exploitation does not require user interaction. The combination of a drastic scope change and a lower exploitation probability still make this vulnerability a top priority for remediation.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the Adobe ColdFusion security update that addresses the improper input validation flaw as soon as it becomes available.
  • Restrict network exposure to ColdFusion services by implementing firewall rules or VPN isolation to limit access to trusted IP ranges.
  • Deploy a web application firewall or enforce strict input filtering on deployed CFML code to block malicious payloads until the patch is installed.
