CVE-2014-3206: Seagate BlackArmor NAS improper input validation enables remote code execution

Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 20 September 2026. Confidence: high.

critical priorityCVSS score is 9.8 (critical), a public exploit exists, and EPSS probability is high, making immediate action necessary.

What it is

Seagate BlackArmor NAS devices fail to properly validate input passed to the session parameter in localhost/backupmgt/localJob.php and the auth_name parameter in localhost/backupmgmt/pre_connect_check.php. This allows remote attackers to execute arbitrary code on the device. The flaw is critical because it requires no authentication or user interaction and can lead to full compromise of the NAS.

Impact

An attacker can execute arbitrary code with the privileges of the web server, potentially gaining complete control of the NAS, accessing stored data, and using the device as a foothold into the network.

Attack surface

The vulnerability is reachable over the network via HTTP requests to the affected PHP scripts. No authentication or user interaction is required, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N).

Exploitation

A public exploit exists (Exploit-DB 33159), and EPSS estimates a 51% probability of exploitation in the next 30 days, though the CVE is not listed in CISA KEV.

What to do

• Apply the latest firmware update from Seagate if available; if no patch exists, isolate the device from untrusted networks.
• Restrict network access to the NAS management interface to trusted IP addresses only.
• Disable remote management and UPnP if not required.
• Monitor for and block exploit attempts targeting the affected PHP endpoints.
• Consider replacing end-of-life devices that no longer receive security updates.

Detection

• Inspect HTTP request logs for POST or GET parameters containing suspicious payloads in localJob.php or pre_connect_check.php.
• Monitor for unexpected outbound connections or processes spawned by the web server on the NAS.
• Use network intrusion detection signatures for known exploit patterns targeting Seagate BlackArmor NAS.
• Audit NAS device logs for unauthorized configuration changes or new user accounts.
