CVE-2024-53298 is a critical security vulnerability identified in Dell PowerScale OneFS, specifically affecting versions 9.5.0.0 through 9.10.0.1. The flaw is categorized under CWE-862, indicating a missing authorization control in the NFS export mechanism. This means that the system fails to properly verify whether a remote request to access the filesystem via NFS is authorized. As a result, an unauthenticated attacker with network access to the affected system can exploit this vulnerability to bypass access controls and gain unauthorized filesystem access. The attacker can perform arbitrary file operations including reading sensitive data, modifying files, or deleting critical data, potentially leading to full system compromise. The vulnerability has a CVSS v3.1 base score of 9.8, reflecting its critical nature with network attack vector, low attack complexity, no privileges required, and no user interaction needed. The scope is unchanged, but the impact on confidentiality, integrity, and availability is high. Dell has acknowledged the issue and recommends upgrading to a fixed version, although no patch links are currently provided. No known exploits have been reported in the wild yet, but the vulnerability’s characteristics make it a prime target for attackers once exploit code becomes available. The affected component, PowerScale OneFS, is widely used in enterprise storage environments, especially where NFS exports are common, increasing the potential attack surface.

The impact of CVE-2024-53298 is severe for organizations worldwide using Dell PowerScale OneFS within their storage infrastructure. Successful exploitation allows attackers to bypass all authorization controls on NFS exports, leading to unauthorized access to sensitive files. This can result in data breaches, data tampering, or destruction of critical files, severely affecting confidentiality, integrity, and availability of enterprise data. Organizations relying on PowerScale OneFS for file storage, backup, or archival services face risks of operational disruption and potential compliance violations due to unauthorized data exposure or loss. The ability to modify or delete files can also facilitate ransomware or destructive attacks. Since no authentication is required, attackers can exploit this vulnerability remotely without user interaction, increasing the likelihood of automated attacks and rapid spread. The absence of known exploits currently provides a window for mitigation, but the critical severity demands immediate attention to prevent potential widespread exploitation.

To mitigate CVE-2024-53298, organizations should prioritize upgrading Dell PowerScale OneFS to the latest patched version as soon as it becomes available from Dell. Until a patch is applied, administrators should restrict network access to NFS exports by implementing strict firewall rules limiting access to trusted hosts only. Disable or limit NFS export services if not required or consider alternative secure file sharing protocols with proper authentication and authorization controls. Monitor network traffic and system logs for unusual access patterns or unauthorized file operations on NFS shares. Employ network segmentation to isolate storage systems from general user networks and untrusted zones. Additionally, implement robust backup and recovery procedures to mitigate potential data loss from exploitation. Engage with Dell support for any interim mitigation guidance and stay updated on advisories or patches. Regularly audit and review NFS export configurations to ensure minimal exposure and adherence to the principle of least privilege.
