Attack Vector: Local
Attack Complexity: Low

User Interaction: None
Vulnerable system confidentiality: Low
Vulnerable system integrity: None
Vulnerable system availability: None
Subsequent system confidentiality: None
Subsequent system integrity: None
Subsequent system availability: None

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

Attack Vector: Local: The vulnerable system is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or through terminal emulation (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., using social engineering techniques to trick a legitimate user into opening a malicious document).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

Exploitation evidence

Disclosed: evidence found.
CVE published 12 Oct 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 26 Oct 2026.

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 or the CVSS exploit maturity 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.

What to do

AI-suggested

Restrict physical access to Furbo 360 and Furbo Mini devices to trusted personnel only, minimizing the risk of local exploitation.
Implement network segmentation to isolate IoT devices from critical business networks, reducing the chance of attackers gaining local access remotely.
Monitor device logs and network traffic for unusual access patterns that could indicate attempts to exploit local vulnerabilities.
If possible, disable debug logging features or restrict access to the debug log storage locations to prevent unauthorized data retrieval.
Regularly audit firmware versions and device configurations to identify affected devices and prepare for future patches.
Engage with Tomofun support channels persistently to request security updates or official patches.
Consider replacing vulnerable devices with alternatives that have stronger security postures if mitigation is not feasible.
Educate staff about the risks of local device access and enforce policies to prevent unauthorized physical or network access to IoT devices.

Description

A vulnerability has been found in Tomofun Furbo 360 and Furbo Mini. The impacted element is an unknown function of the file collect_logs.sh of the component Debug Log S3 Bucket Handler. The manipulation leads to insecure storage of sensitive information. An attack has to be approached locally. The firmware versions determined to be affected are Furbo 360 up to FB0035_FW_036 and Furbo Mini up to MC0020_FW_074. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations, the primary impact of this vulnerability lies in the potential exposure of sensitive information stored on Furbo 360 and Furbo Mini devices. These devices are commonly used in private homes but may also be present in office environments for pet monitoring. If an attacker gains local access—through physical access or compromised internal networks—they could retrieve sensitive debug logs containing private user data or device information. This could lead to privacy violations, data leakage, and potential further compromise if the logs contain credentials or network details. Although the vulnerability does not directly affect device availability or integrity, the confidentiality impact is significant, especially under GDPR regulations that mandate protection of personal data. Organizations using these devices should consider the risk of insider threats or unauthorized physical access. The lack of vendor response and patches increases the risk exposure duration. While the attack requires local access, environments with weak physical security or insufficient network segmentation may be vulnerable. The impact is thus more pronounced in settings where these devices are deployed in sensitive or regulated environments.
