Critical

Unauthorized NFS root export access in EMC Celerra NAS

IdentifiersCVE-2010-2860CWE-284

CVE-2010-2860 is an unauthorized access vulnerability in EMC Celerra Network Attached Storage and Unified Storage systems. The appliance accepts external network traffic addressed to IP ranges intended for its internal intranet network, and its NFS service exports the root filesystem. Access control relies on a factory-defined list of authorized internal IP addresses rather than effective network isolation. An attacker who can spoof one of those authorized internal addresses can mount the exported root filesystem remotely. Because the NFS export does not enforce root squashing, mounting as UID 0 yields root-level access to the exposed filesystem content. This allows unauthorized reading, creation, and modification of arbitrary files within the user data directory, including data exposed through related storage services.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows a remote attacker to bypass intended network trust boundaries and obtain unauthorized root-level access over NFS to exposed storage content. The attacker can read, create, modify, or overwrite arbitrary files in the user data directory and may affect data presented through CIFS shares and iSCSI-mounted storage. The primary impact is compromise of confidentiality and integrity of stored data, with potential secondary operational impact if critical files are altered or deleted.

Mitigation

If you can’t patch tonight, do this now.

Until the permanent fix is deployed, reduce exploitability by hiding the root export from enumeration, changing the default internal IP addresses used by the appliance, enforcing network-layer rules that reject traffic destined for internal Celerra network addresses, placing firewalls between Data Movers and NFS clients to block such traffic, and disabling IP reflect. These measures are intended to prevent attackers from reaching or successfully abusing the internal-address trust model used by the vulnerable NFS service.

Remediation

Patch, then assume compromise.

Apply the vendor's permanent code fix for CVE-2010-2860 when available for the affected EMC Celerra platform. In the interim, implement the vendor-recommended workaround measures to prevent external systems from reaching internal appliance IP addresses and to reduce exposure of the root NFS export. Validate that the appliance no longer accepts traffic destined for internal-only addresses and that NFS export behavior aligns with the corrected vendor guidance after patching.
