CVE-2025-13454 is a vulnerability identified in the Lenovo ThinkPlus FU100 Gen 1 device, specifically within its configuration software. The issue stems from the cleartext transmission of sensitive information, classified under CWE-319, which refers to the exposure of sensitive data during transmission without adequate encryption. This vulnerability allows a local authenticated user—someone with legitimate but limited access to the device—to intercept or access sensitive device information that should otherwise be protected. The CVSS 4.0 vector indicates the attack requires local access (AV:L), low attack complexity (AC:L), and privileges (PR:L), but no user interaction (UI:N). The vulnerability impacts confidentiality (VC:H) but does not affect integrity or availability. Since the transmission is cleartext, sensitive data such as configuration details, credentials, or device identifiers could be exposed to an attacker with local access. No known exploits have been reported in the wild, and no patches have been released at the time of this analysis. The vulnerability was reserved in November 2025 and published in January 2026, indicating recent discovery. The lack of network attack vector limits remote exploitation, but insider threats or compromised local accounts pose a risk. The absence of user interaction and the medium CVSS score reflect a moderate threat level, emphasizing the need for local access controls and encryption of sensitive data in future updates.

For European organizations, the primary impact of CVE-2025-13454 is the potential unauthorized disclosure of sensitive device information, which could lead to further targeted attacks or compromise of device integrity indirectly. Confidentiality breaches could expose configuration settings, device identifiers, or credentials that attackers might leverage for lateral movement or privilege escalation. Sectors with high reliance on Lenovo ThinkPlus FU100 devices, such as manufacturing, logistics, or enterprise IT environments, could face operational risks if sensitive information is leaked. The vulnerability does not directly affect system integrity or availability, so immediate disruption is unlikely. However, the exposure of sensitive information could facilitate subsequent attacks, increasing overall risk. European organizations with strict data protection regulations (e.g., GDPR) must consider the compliance implications of such data exposure. The local access requirement reduces the attack surface but raises concerns about insider threats or compromised endpoints within secure facilities. Overall, the vulnerability represents a moderate risk that should be addressed promptly to prevent escalation.

To mitigate CVE-2025-13454, European organizations should implement the following specific measures: 1) Restrict and monitor local access to Lenovo ThinkPlus FU100 devices, ensuring only authorized personnel can interact with the configuration software. 2) Employ endpoint security solutions to detect and prevent unauthorized local access or suspicious activities around these devices. 3) Use network segmentation and access controls to limit exposure of devices to only trusted users and systems. 4) Encrypt sensitive data at rest and in transit where possible, and advocate for Lenovo to release patches that enforce encrypted communication within the configuration software. 5) Conduct regular audits of device configurations and access logs to identify potential misuse or data leakage. 6) Train staff on the risks of insider threats and the importance of safeguarding device access credentials. 7) Prepare incident response plans that include scenarios involving local data exposure. 8) Engage with Lenovo support channels to obtain updates or workarounds and apply patches promptly once available. These steps go beyond generic advice by focusing on local access control, monitoring, and proactive engagement with the vendor.
