This vulnerability could allow a remote authenticated user to move or access files belonging to other users on the same device. The vulnerability stems from a failure to properly validate file paths, potentially leading to path traversal. This issue allows an attacker with valid credentials to elevate their privileges and access sensitive information stored on the device outside of their designated file paths. Defenders need to ensure that Lenovo Personal Cloud Storage devices are properly secured and monitored for unauthorized file access attempts.

Attack Chain

1. The attacker gains valid credentials to a Lenovo Personal Cloud Storage device through existing account compromise.
2. The attacker authenticates to the Lenovo Personal Cloud Storage device via the web interface or API.
3. The attacker crafts a malicious request to move or access a file, including a path traversal sequence (e.g., “../”) in the file path parameter.
4. The Lenovo Personal Cloud Storage device improperly validates the file path, failing to restrict access to authorized directories.
5. The attacker successfully moves or accesses a file or directory outside of their authorized scope.
6. The attacker reads sensitive files belonging to other users, such as documents, photos, or configuration files.
7. The attacker modifies or deletes files belonging to other users, leading to data corruption or denial of service.
8. The attacker exfiltrates the stolen data.

Impact

Successful exploitation of CVE-2026-6282 could allow an attacker with valid user credentials to access and manipulate files belonging to other users on the affected Lenovo Personal Cloud Storage device. This could lead to unauthorized access to sensitive information, data breaches, data corruption, or denial of service. The CVSS v3.1 base score for this vulnerability is 8.1, indicating a high severity.

Recommendation

• Apply available patches or mitigations released by Lenovo to address CVE-2026-6282 on affected Personal Cloud Storage devices, as referenced in the Lenovo advisory URLs.
• Monitor web server logs for suspicious requests containing path traversal sequences (e.g., “../”) targeting file access endpoints using the Sigma rule provided below.
• Implement strict input validation and sanitization on file path parameters within the Lenovo Personal Cloud Storage application to prevent path traversal vulnerabilities (CWE-22).

This vulnerability could allow a remote authenticated user on the local network to execute arbitrary commands on the device. Successful exploitation of this vulnerability could allow an attacker to gain complete control over the affected device, potentially leading to data theft, modification, or denial of service. The vulnerability has a CVSS v3.1 base score of 8.8, indicating a high severity. Lenovo has provided references to advisories and end-of-life notices regarding these devices.

Attack Chain

1. Attacker gains initial access to the local network.
2. Attacker authenticates to the Lenovo Personal Cloud Storage device.
3. Attacker crafts a malicious request to exploit the OS command injection vulnerability (CWE-78).
4. The crafted request is sent to the vulnerable endpoint on the device.
5. The device fails to properly sanitize the input, leading to command execution.
6. The attacker executes arbitrary commands on the device’s operating system.
7. Attacker leverages the gained access to move laterally within the device, escalating privileges if necessary.
8. Attacker achieves the final objective, such as data exfiltration or deploying malicious software.

Impact

Successful exploitation of CVE-2026-6281 allows a remote, authenticated attacker on the local network to execute arbitrary commands on the affected Lenovo Personal Cloud Storage device. This can lead to complete compromise of the device, including data theft, modification, or denial of service. Since the device is intended for personal cloud storage, sensitive user data is at risk. The number of affected devices and users is currently unknown.

Recommendation

• Deploy the Sigma rule Detect CVE-2026-6281 Exploitation Attempt via Crafted HTTP Request to your SIEM and tune for your environment. This rule detects attempts to exploit the vulnerability via suspicious HTTP requests.
• Monitor network traffic for unusual command execution activity originating from Lenovo Personal Cloud Storage devices by enabling network connection logging to activate the rule Detect Suspicious Network Activity from Lenovo Storage Device.
• Refer to the Lenovo advisory at https://iknow.lenovo.com.cn/detail/440274 and https://pc.lenovo.com.cn/tips/Ann/t1_eol.html for specific remediation advice.
