Overview
CVE-2025-58484 is a medium severity vulnerability affecting Samsung Cloud Assistant versions prior to 8.0.03.8. The vulnerability stems from incorrect default permissions, which can allow a local attacker to gain access to partial data stored within the application’s sandbox environment. This can potentially lead to unauthorized access to sensitive information managed by the Cloud Assistant.
Technical Details
The vulnerability lies in the insufficient access controls applied to the sandbox directory and its contents by Samsung Cloud Assistant. Due to the overly permissive default permissions, another application running locally on the same device, with appropriate permissions (e.g., file system access), can bypass the intended isolation and read files stored within the Cloud Assistant’s sandbox. This access is limited to a portion of the data but is still considered a security risk.
CVSS Analysis
- CVSS Score: 4.0
- Severity: MEDIUM
This CVSS score reflects the vulnerability’s limited attack vector (local access only), the partial confidentiality impact, and the need for specific pre-conditions (another application with file system access). The score indicates a moderate level of risk.
Possible Impact
Successful exploitation of CVE-2025-58484 could allow a malicious application to:
- Read configuration files or temporary data stored in the sandbox.
- Potentially extract user-specific information, depending on the data stored.
- Gain insights into the Cloud Assistant’s internal workings, which could be used to discover further vulnerabilities.
While the attacker’s access is limited, the exposed data could be used for reconnaissance or as part of a more complex attack chain.
Mitigation or Patch Steps
The vulnerability is addressed in Samsung Cloud Assistant version 8.0.03.8 and later. Users are strongly advised to update their Samsung Cloud Assistant to the latest version available through the Galaxy Store or their device’s software update mechanism.
- Update Samsung Cloud Assistant: Ensure your device has the latest version of the app installed.
- Regularly Check for Updates: Keep your device and all installed applications up to date.
