CVE-2025-11193 identifies a vulnerability in Lenovo Tab M11 TB330FU and TB330XU tablets related to the plaintext storage of passwords on the device, classified under CWE-256. This vulnerability allows a local authenticated user or application to access sensitive device-specific information, including stored passwords, due to improper credential storage mechanisms. The vulnerability does not require user interaction or additional authentication beyond local access, making it easier for malicious insiders or compromised applications to exploit. The CVSS 4.0 vector indicates an attack vector of local (AV:L), low attack complexity (AC:L), no privileges required beyond local authentication (PR:L), no user interaction (UI:N), and a high impact on confidentiality (VC:H) with no impact on integrity or availability. This means that while the device’s confidentiality is at risk, its integrity and availability remain unaffected. The vulnerability was published on November 3, 2025, and no patches or known exploits are currently reported. The root cause is the insecure storage of passwords in plaintext, which can be extracted by an attacker with local access, potentially leading to credential theft and unauthorized access to device or network resources. This vulnerability is particularly concerning in environments where devices are shared or where local access controls are weak. Since the affected devices are Lenovo tablets, commonly used in both consumer and enterprise settings, the risk extends to organizations relying on these devices for business operations. The lack of available patches necessitates interim mitigations to reduce exposure until a vendor fix is released.

For European organizations, this vulnerability poses a significant confidentiality risk as attackers with local access can retrieve plaintext passwords, potentially leading to unauthorized access to sensitive information or lateral movement within corporate networks. The impact is heightened in environments where Lenovo Tab M11 tablets are used for business-critical applications or contain access credentials for enterprise systems. Compromise of these devices could lead to data breaches, loss of intellectual property, or unauthorized access to internal resources. The vulnerability does not affect device integrity or availability directly but undermines trust in device security. Organizations with shared device usage or insufficient physical security controls are particularly vulnerable. Additionally, the lack of user interaction or complex exploitation steps lowers the barrier for attackers with local access, increasing the likelihood of exploitation in insider threat scenarios or through malicious applications. The absence of known exploits in the wild currently limits immediate risk but does not preclude future exploitation. Overall, the vulnerability could facilitate targeted attacks against European enterprises, especially in sectors with high reliance on mobile computing and sensitive data handling.

To mitigate this vulnerability, European organizations should implement strict physical and logical access controls to prevent unauthorized local access to Lenovo Tab M11 devices. Employ device encryption and strong authentication mechanisms to protect stored data and credentials. Monitor and restrict installation of untrusted applications that could exploit local access to extract plaintext passwords. Until Lenovo releases an official patch, consider deploying Mobile Device Management (MDM) solutions to enforce security policies and remotely wipe compromised devices. Conduct regular audits of device security configurations and educate users on the risks of local device compromise. Additionally, isolate vulnerable devices from critical network segments to limit potential lateral movement. Organizations should maintain close communication with Lenovo for timely patch releases and apply updates promptly once available. Implementing endpoint detection and response (EDR) tools can help identify suspicious local activities indicative of exploitation attempts. Finally, consider alternative devices or platforms with stronger credential storage protections for high-risk environments.
