CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N

Attack Vector: Network
Attack Complexity: Low
Privileges Required: None
User Interaction: Required
Scope: Unchanged
Confidentiality: None
Integrity: Low
Availability: None

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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 16 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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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

1. Educate users to avoid clicking on suspicious or untrusted web content, especially when logged into the CHOCO TEI WATCHER mini device interface. 2. Implement network segmentation to isolate the device from general internet access, reducing exposure to malicious web pages. 3. Employ web content filtering and endpoint security solutions to block access to known malicious sites. 4. Monitor device logs and behavior for anomalies indicative of unintended operations. 5. Engage with the vendor to obtain timelines for patches or firmware updates addressing this vulnerability. 6. Consider deploying browser security features or extensions that prevent clickjacking or frame overlay attacks. 7. If feasible, restrict device UI access to dedicated terminals or secure environments to minimize exposure to malicious web content. 8. Maintain an incident response plan specific to device integrity issues to quickly address any exploitation attempts.

Description

CHOCO TEI WATCHER mini (IB-MCT001) contains an issue with improper restriction of rendered UI layers or frames. If a user clicks on content on a malicious web page while logged into the product, unintended operations may be performed on the product.

Impact

For European organizations, the primary impact is on the integrity of operations performed by the CHOCO TEI WATCHER mini device. If exploited, attackers could cause the device to perform unintended actions, potentially leading to incorrect monitoring data, erroneous control commands, or operational disruptions. While confidentiality and availability are not directly impacted, the integrity compromise could affect decision-making processes or automated systems relying on accurate device behavior. Sectors such as manufacturing, industrial automation, or utilities that deploy this device for monitoring or control could face operational risks. The requirement for user interaction limits large-scale automated exploitation but does not eliminate targeted attacks, especially in environments where users might be tricked into clicking malicious links. The absence of known exploits reduces immediate risk but underscores the need for vigilance. The lack of patches means organizations must rely on compensating controls until updates are available.
