Overview
A high-severity vulnerability, identified as CVE-2025-64642, has been discovered in NMIS/BioDose versions V22.02 and earlier. This vulnerability stems from insecure default file permissions on the software’s installation directory paths. In specific deployment scenarios, this flaw could allow users on client workstations to modify the program’s executables and libraries, potentially leading to significant security breaches.
Technical Details
The vulnerability arises from overly permissive file permissions granted to the installation directories of NMIS/BioDose software. Specifically, client workstation users might inadvertently or maliciously gain write access to critical system files. This access can be exploited to replace legitimate program components with malicious ones, leading to arbitrary code execution, data corruption, or denial of service.
CVSS Analysis
This vulnerability has been assigned a CVSS score of 8.0 (High), indicating its significant potential for exploitation and impact. The high score reflects the ease of exploitation and the potential for widespread damage. A successful exploit could compromise the integrity and availability of the NMIS/BioDose system.
Possible Impact
The exploitation of CVE-2025-64642 could have severe consequences, including:
- Arbitrary Code Execution: Attackers could execute malicious code on the affected system.
- Data Corruption: Critical data managed by NMIS/BioDose could be altered or destroyed.
- Denial of Service: The system could be rendered unusable, disrupting critical healthcare operations.
- Privilege Escalation: An attacker could potentially gain elevated privileges on the affected workstation.
- Compromise of Sensitive Patient Data: If NMIS/BioDose handles patient data, this data could be at risk.
Mitigation or Patch Steps
To address this vulnerability, the following mitigation steps are recommended:
- Apply the Patch: Check with the vendor for an official patch or update for NMIS/BioDose to address CVE-2025-64642. This is the most effective solution.
- Restrict File Permissions: Carefully review and restrict file permissions on the NMIS/BioDose installation directories. Ensure that only authorized users and processes have write access. Implement the principle of least privilege.
- Network Segmentation: Isolate NMIS/BioDose systems on a separate network segment to limit the potential impact of a successful exploit.
- Endpoint Security: Ensure all client workstations accessing NMIS/BioDose have up-to-date antivirus software and endpoint detection and response (EDR) systems installed.
- Monitor System Logs: Regularly review system logs for suspicious activity that might indicate an attempted or successful exploit.
