CVE-2025-2769 is a local privilege escalation vulnerability affecting Bdrive NetDrive 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 the product. Specifically, NetDrive loads its OpenSSL configuration from an insecure location that can be manipulated by a local attacker. This improper configuration allows an attacker who already has the ability to execute code with low privileges on the affected system to escalate their privileges to SYSTEM level. The vulnerability is classified under CWE-427, which pertains to uncontrolled search path elements that can lead to execution of malicious code. Exploitation requires the attacker to have initial local code execution capabilities, but no further authentication or user interaction is necessary once that foothold is obtained. Successful exploitation enables arbitrary code execution with the highest system privileges, potentially compromising the entire system's confidentiality, integrity, and availability. As of the publication date, no public exploits or active exploitation in the wild have been reported. The vulnerability was identified and reserved by the Zero Day Initiative (ZDI) under ZDI-CAN-25295. No patches have been released yet, increasing the urgency for affected organizations to implement mitigations. The vulnerability specifically targets the way NetDrive handles OpenSSL configuration files, which is a critical component for secure communications and cryptographic operations within the product. Improper handling of these files can lead to loading malicious configurations or libraries, facilitating privilege escalation.

For European organizations using Bdrive NetDrive 3.17.960, this vulnerability poses a significant risk. Since exploitation requires local code execution, the threat is particularly relevant in environments where users may run untrusted code or where endpoint security is weak. Once exploited, attackers can gain SYSTEM-level privileges, allowing them to bypass security controls, access sensitive data, install persistent malware, or disrupt critical services. This can lead to data breaches, operational downtime, and loss of trust. Organizations in sectors with high regulatory requirements such as finance, healthcare, and critical infrastructure could face severe compliance and reputational consequences. Additionally, because NetDrive is often used for network drive mapping and file access, compromise could facilitate lateral movement within corporate networks, amplifying the impact. The lack of a patch means that European enterprises must rely on compensating controls to mitigate risk. The vulnerability also undermines the security of cryptographic operations within NetDrive, potentially exposing encrypted communications or stored credentials to compromise if exploited.

1. Immediate mitigation should focus on restricting local code execution capabilities to trusted users only, minimizing the risk of initial foothold by attackers. 2. Implement strict file system permissions on directories where OpenSSL configuration files are stored to prevent unauthorized modification or replacement. 3. Employ application whitelisting to prevent execution of unauthorized binaries or scripts that could exploit this vulnerability. 4. Monitor and audit file changes in the OpenSSL configuration paths used by NetDrive to detect suspicious activity. 5. Use endpoint detection and response (EDR) solutions to identify and block privilege escalation attempts. 6. Network segmentation can limit the ability of an attacker to move laterally after exploitation. 7. Until an official patch is released, consider disabling or restricting the use of NetDrive on critical systems where possible. 8. Engage with Bdrive support or vendor communications to obtain updates on patch availability and apply them promptly once released. 9. Educate users about the risks of running untrusted code locally and enforce least privilege principles to reduce attack surface.
