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

Attack Vector: Physical: The attack requires the attacker to physically touch or manipulate the vulnerable system. Physical interaction may be brief (e.g., evil maid attack) or persistent.
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: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: High: There is a total loss of confidentiality, resulting in all information within the Vulnerable System being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server.
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 14 Jan 2026
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.

AI-suggested

To mitigate the risks posed by CVE-2025-13453, organizations should implement the following specific measures: 1) Immediately audit and identify all Lenovo ThinkPlus FU100 Gen 1 USB drives in use and restrict their use for storing sensitive data. 2) Enforce strict physical security controls to prevent unauthorized access to USB drives, including secure storage and access logging. 3) Replace affected USB drives with devices that provide hardware-based encryption or use software encryption solutions such as BitLocker To Go or VeraCrypt to secure data before writing to the drive. 4) Implement endpoint security policies that disable or restrict USB port usage where feasible to reduce data exfiltration risks. 5) Educate employees on the risks of using unencrypted portable storage and enforce data handling policies that prohibit storing sensitive information on unencrypted devices. 6) Monitor for lost or stolen devices and have an incident response plan to address potential data breaches. 7) Engage with Lenovo for updates or firmware patches and apply them promptly once available. These steps go beyond generic advice by focusing on device inventory, encryption enforcement, and organizational policy adjustments tailored to this vulnerability.

Description

A potential vulnerability was reported in some ThinkPlus USB drives that could allow a user with physical access to read data stored on the drive.

Impact

The primary impact of CVE-2025-13453 is the compromise of data confidentiality. Organizations relying on Lenovo ThinkPlus FU100 Gen 1 USB drives for storing sensitive or proprietary information face the risk of data leakage if the devices fall into unauthorized hands. This could lead to exposure of intellectual property, personal identifiable information (PII), or confidential business data. Although the vulnerability does not affect data integrity or availability, the breach of confidentiality alone can result in regulatory non-compliance, reputational damage, and potential financial losses. The requirement for physical access limits the scope of exploitation to scenarios involving lost, stolen, or improperly secured devices. However, in environments with high employee turnover, travel, or remote work, the risk of physical device compromise increases. The absence of encryption also undermines trust in the device's security, potentially affecting Lenovo's reputation and customer confidence.

Class weaknessLikelihood of exploit: HighOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The product does not encrypt sensitive or critical information before storage or transmission.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Requirements
Clearly specify which data or resources are valuable enough that they should be protected by encryption. Require that any transmission or storage of this data/resource should use well-vetted encryption algorithms.
Architecture and Design
Ensure that encryption is properly integrated into the system design, including but not necessarily limited to: Encryption that is needed to store or transmit private data of the users of the system; Encryption that is needed to protect the system itself from unauthorized disclosure or tampering
Architecture and Design · Libraries or Frameworks
When there is a need to store or transmit sensitive data, use strong, up-to-date cryptographic algorithms to encrypt that data. Select a well-vetted algorithm that is currently considered to be strong by experts in the field, and use well-tested implementations.
