Overview
A high-severity path traversal vulnerability, identified as CVE-2025-54160, has been discovered in Synology BeeDrive for desktop. This vulnerability allows local users to execute arbitrary code due to improper limitation of pathname to a restricted directory. Users of BeeDrive are strongly advised to update to the latest version to mitigate this risk.
Technical Details
The vulnerability resides in how BeeDrive handles file paths, specifically when processing user-supplied input for file operations. Due to insufficient validation, a local attacker can craft a malicious file path that traverses outside the intended restricted directory. This can lead to the execution of arbitrary code with the privileges of the BeeDrive application.
The attack vector involves manipulating file paths to include “..” sequences or absolute paths that point to sensitive system locations. This allows the attacker to bypass security checks and perform unauthorized actions on the system.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) assigns this vulnerability a score of 7.8, indicating a high severity. The detailed breakdown is as follows:
- CVSS Score: 7.8
- Vector: The specific CVSS vector string is not provided in the initial information. Typically it would include elements describing attack vector, complexity, privileges required etc.
Possible Impact
Successful exploitation of this vulnerability could have serious consequences:
- Arbitrary Code Execution: An attacker can execute arbitrary code on the affected system, potentially gaining complete control.
- Data Breach: Sensitive data stored on the system could be accessed and exfiltrated.
- System Compromise: The entire system could be compromised, leading to further malicious activities.
- Denial of Service: The BeeDrive application or even the entire system could be rendered unusable.
Mitigation or Patch Steps
Synology has released a patch to address this vulnerability. Users are strongly advised to take the following steps:
- Update BeeDrive: Upgrade to BeeDrive for desktop version 1.4.2-13960 or later. This update contains the necessary fix to properly validate file paths and prevent path traversal attacks.
- Verify Update: After updating, verify that the BeeDrive application is running the patched version.
- Monitor System: Monitor the system for any suspicious activity that may indicate exploitation of the vulnerability.
