CVE-2025-2768 is a local privilege escalation vulnerability affecting Bdrive's NetDrive product, specifically version 3.17.960. The root cause of this vulnerability lies in an uncontrolled search path element related to the OpenSSL configuration file used by NetDrive. The product loads the OpenSSL configuration from an unsecured location, which can be manipulated by an attacker who already has the ability to execute low-privileged code on the target system. By placing a malicious OpenSSL configuration file in this insecure path, the attacker can escalate their privileges to SYSTEM level, thereby gaining full control over the affected machine. This vulnerability is categorized under CWE-427, which refers to uncontrolled search path elements that can lead to code execution or privilege escalation. Exploitation requires local access and the ability to run code with limited privileges, but does not require user interaction beyond that. There are no known exploits in the wild at the time of this report, and no patches have been released yet. The vulnerability was reserved and published in early 2025 and was identified by the Zero Day Initiative (ZDI) as ZDI-CAN-25041. The severity is currently rated as medium, reflecting the prerequisite of local code execution and the potential impact of full SYSTEM-level compromise.

For European organizations, the impact of this vulnerability can be significant, especially in environments where Bdrive NetDrive is used to map network drives or manage remote storage. Successful exploitation would allow an attacker with limited access to escalate privileges to SYSTEM, potentially leading to full system compromise, unauthorized data access, and lateral movement within the network. This could result in data breaches, disruption of business operations, and compromise of sensitive information. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and critical infrastructure, could face regulatory and reputational damage. Since the vulnerability requires local code execution, it is particularly concerning in environments where endpoint security is weak or where attackers can gain initial footholds through phishing or other means. The lack of a patch increases the risk window, and the uncontrolled loading of OpenSSL configuration files could be exploited by insiders or malware that gains limited access.

To mitigate this vulnerability, European organizations should take several specific actions beyond generic advice: 1) Immediately audit all systems running Bdrive NetDrive version 3.17.960 to identify affected installations. 2) Restrict write permissions on directories and paths where OpenSSL configuration files are loaded to prevent unauthorized modification or replacement. 3) Implement application whitelisting and endpoint protection solutions that can detect and block unauthorized file modifications and suspicious local code execution. 4) Employ strict access controls and least privilege principles to limit the ability of users and processes to write to system or application directories. 5) Monitor logs and file integrity for changes to OpenSSL configuration files or related directories. 6) Isolate systems running NetDrive in segmented network zones to reduce the risk of lateral movement if compromise occurs. 7) Engage with Bdrive support or vendors for updates or patches and apply them promptly once available. 8) Educate users and administrators about the risks of local code execution vulnerabilities and enforce strong endpoint security hygiene to reduce initial compromise vectors.
