Scope: Changed
Confidentiality: None
Integrity: High
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Adjacent: The vulnerable component is bound to the network stack, but the attack is limited at the protocol level to a logically adjacent topology. This can mean an attack must be launched from the same shared physical (e.g., Bluetooth or IEEE 802.11) or logical (e.g., local IP subnet) network, or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN to an administrative network zone).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 9 Dec 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

European organizations should implement the following specific mitigations: 1) Immediately audit and restrict privileged access to ColdFusion servers to minimize the risk of attackers obtaining the required high privileges. 2) Employ strict input validation and sanitization controls at the application level to reduce the attack surface. 3) Monitor file system changes on ColdFusion servers using integrity monitoring tools to detect unauthorized file writes promptly. 4) Isolate ColdFusion servers within segmented network zones with limited access to reduce the adjacent network attack vector. 5) Regularly review and update ColdFusion versions and apply vendor patches as soon as they become available. 6) Implement robust logging and alerting mechanisms focused on suspicious file write activities and privilege escalations. 7) Conduct penetration testing and vulnerability assessments specifically targeting ColdFusion environments to identify and remediate weaknesses. 8) Educate system administrators on the risks of privilege misuse and enforce the principle of least privilege. These measures go beyond generic advice by focusing on privilege management, monitoring, and network segmentation tailored to the nature of this vulnerability.

Description

ColdFusion versions 2025.4, 2023.16, 2021.22 and earlier are affected by an Improper Input Validation vulnerability that could lead to arbitrary file system write. An attacker could exploit this vulnerability to write malicious files to arbitrary locations on the file system. Exploitation of this issue does not require user interaction and scope is changed.

Impact

For European organizations, this vulnerability poses a moderate risk primarily to the integrity of systems running Adobe ColdFusion. Successful exploitation could allow attackers to deploy malicious files, potentially leading to unauthorized code execution, backdoors, or persistence mechanisms. This is particularly concerning for enterprises relying on ColdFusion for critical web applications, as it could facilitate lateral movement or data manipulation. Although exploitation requires high privileges, environments with weak internal controls or compromised credentials are vulnerable. The lack of required user interaction increases the risk in automated or unattended systems. Disruption to business operations, reputational damage, and compliance issues could arise if attackers leverage this vulnerability. Sectors such as finance, government, and manufacturing, which often use ColdFusion for internal and external applications, may face heightened risks. The medium severity rating suggests that while immediate widespread exploitation is unlikely, targeted attacks against high-value assets could have significant consequences.

MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Attack Surface Reduction
Consider using language-theoretic security (LangSec) techniques that characterize inputs using a formal language and build "recognizers" for that language.

Use an input validation framework such as Struts or the OWASP ESAPI Validation API. Note that using a framework does not automatically address all input validation problems; be mindful of weaknesses that could arise from misusing the framework itself (CWE-1173).
