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: None: The vulnerable system can be exploited without any interaction from any user.
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: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

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. Network Segmentation: Isolate CHOCO TEI WATCHER mini devices on dedicated network segments with strict access controls to limit exposure to untrusted networks. 2. Access Control: Restrict access to the Video Download interface to trusted IP addresses only, using firewall rules or network ACLs. 3. Monitoring and Detection: Implement network monitoring to detect unusual or malformed requests targeting the Video Download interface, enabling early detection of exploitation attempts. 4. Vendor Coordination: Engage with Inaba Denki Sangyo Co., Ltd. to obtain patches or firmware updates addressing the vulnerability as soon as they become available. 5. Incident Response Preparation: Develop and test response plans for potential denial of service incidents involving these devices to minimize operational impact. 6. Device Hardening: Disable or restrict unused interfaces and services on the device to reduce the attack surface. 7. Regular Updates: Maintain an inventory of deployed devices and ensure timely application of security updates once released. 8. Alternative Solutions: Where feasible, consider deploying alternative devices with stronger security postures until patches are available.

Description

CHOCO TEI WATCHER mini (IB-MCT001) contains an issue with improper check for unusual or exceptional conditions. If a remote attacker sends a specially crafted request to the Video Download interface, the system may become unresponsive.

Impact

The primary impact of CVE-2025-61976 is on the availability of the CHOCO TEI WATCHER mini devices, leading to denial of service. For European organizations, particularly those relying on these devices for video surveillance, monitoring, or security operations, this could result in significant operational disruptions. Loss of video feed availability may impair physical security monitoring, incident response, and compliance with regulatory requirements for surveillance. Critical infrastructure sectors such as transportation, manufacturing, and public safety that deploy these devices could face increased risk exposure. Additionally, prolonged unavailability could lead to financial losses, reputational damage, and potential safety hazards. Since the vulnerability does not affect confidentiality or integrity, data breaches or manipulation are less likely. However, the ease of remote exploitation without authentication increases the risk of widespread disruption if attackers target these devices en masse. The absence of known exploits currently provides a window for mitigation, but the threat remains significant given the device’s role in security environments.
