CVE-2025-0287 is a medium-severity vulnerability identified in Paragon Software's product 'Migrate OS to SSD' version 4. The flaw is a NULL pointer dereference within the kernel-mode driver component biontdrv.sys. This vulnerability arises due to the absence of a valid MasterLrp structure in the input buffer processed by the driver. When the driver attempts to dereference this null pointer, it can lead to undefined behavior, including potential arbitrary code execution in kernel mode. Exploiting this vulnerability allows an attacker to escalate privileges by executing code with kernel-level permissions, which can compromise the entire system's integrity and security. The CVSS v3.1 base score is 5.1, reflecting a medium severity level. The attack vector is local (AV:L), meaning the attacker must have local access to the system. The attack complexity is low (AC:L), and no privileges or user interaction are required (PR:N, UI:N). The impact on confidentiality and integrity is low, with no impact on availability. No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability is categorized under CWE-476 (NULL Pointer Dereference), a common programming error that can lead to system crashes or code execution if exploited correctly.

For European organizations, this vulnerability poses a risk primarily in environments where Paragon's 'Migrate OS to SSD' version 4 is deployed, especially in IT infrastructure involving OS migration or disk management tasks. Successful exploitation could allow an attacker with local access—such as an insider threat or someone with limited user privileges—to escalate their privileges to kernel level, potentially leading to full system compromise. This could result in unauthorized access to sensitive data, disruption of critical services, or the establishment of persistent footholds within enterprise networks. Given the local attack vector, remote exploitation is not feasible, reducing the risk from external attackers but increasing the importance of internal security controls. Organizations with strict endpoint security and access controls will be better positioned to mitigate this threat. However, sectors with high reliance on disk migration tools, such as IT service providers, data centers, and enterprises undergoing hardware refresh cycles, may face higher exposure.

To mitigate this vulnerability effectively, European organizations should: 1) Immediately inventory and identify all systems running Paragon Software's 'Migrate OS to SSD' version 4. 2) Restrict local access to these systems to trusted personnel only, enforcing strict access controls and monitoring. 3) Employ application whitelisting and endpoint protection solutions capable of detecting anomalous behavior indicative of privilege escalation attempts. 4) Implement robust logging and alerting for kernel-level driver activities to detect exploitation attempts early. 5) Until an official patch is released, consider disabling or uninstalling the affected software on non-critical systems or using alternative disk migration tools with no known vulnerabilities. 6) Educate IT staff and users about the risks of local privilege escalation vulnerabilities and enforce the principle of least privilege to minimize potential attack surfaces. 7) Regularly review and update security policies to include monitoring for exploitation techniques related to kernel driver vulnerabilities.
