Overview
This article details a directory traversal vulnerability identified as CVE-2025-63371 affecting Milos Paripovic’s OneCommander version 3.102.0.0. This vulnerability resides within the application’s ZIP file processing component, specifically the functionality responsible for extracting and handling the contents of ZIP archives. An attacker could potentially exploit this vulnerability to write files to arbitrary locations on the file system, potentially leading to code execution or data compromise.
Technical Details
The core issue lies in the insufficient validation of file paths embedded within ZIP archives processed by OneCommander. Specifically, when extracting files from a ZIP archive, OneCommander fails to properly sanitize or normalize the file paths. This allows an attacker to create a malicious ZIP archive containing entries with specially crafted paths (e.g., using “../” sequences) that, when extracted, will write files outside of the intended destination directory. By crafting a ZIP archive with such malicious pathnames, an attacker can overwrite critical system files, inject malicious code, or exfiltrate sensitive data.
CVSS Analysis
Currently, a CVSS score is not available for CVE-2025-63371. Further analysis is required to determine the base score, environmental score, and temporal score. However, given the nature of the vulnerability, which allows for directory traversal, it is likely to be rated as a high severity vulnerability if successfully exploited. A full CVSS analysis will consider factors such as attack vector, attack complexity, privileges required, user interaction, scope, confidentiality impact, integrity impact, and availability impact.
Possible Impact
The potential impact of this directory traversal vulnerability is significant. Successful exploitation could lead to:
- Arbitrary File Overwrite: Overwriting critical system files, potentially leading to system instability or denial of service.
- Remote Code Execution: Writing executable files to locations where they can be executed by the system, granting the attacker control over the affected machine.
- Data Exfiltration: Reading sensitive data from locations outside the intended destination directory.
- Privilege Escalation: Under certain circumstances, gaining elevated privileges on the system.
Mitigation or Patch Steps
The primary mitigation strategy is to update OneCommander to a patched version that addresses this vulnerability. Users should check the official OneCommander website for updates and install the latest version as soon as it becomes available. In the interim, consider the following:
- Avoid Opening Untrusted ZIP Archives: Exercise caution when opening ZIP archives from untrusted sources.
- Implement File Integrity Monitoring: Monitor critical system files for unauthorized modifications.
- Restrict User Permissions: Limit user permissions to prevent the writing of files to sensitive system directories.
