Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Dell PowerScale OneFS versions 9.4.0.x through 9.7.0.x contains an UNIX symbolic link (symlink) following vulnerability. A local high privileged attacker could potentially exploit this vulnerability, leading to denial of service, information tampering.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Dell PowerScale OneFS versions 9.4.0.x through 9.7.0.x contains a symlink following vulnerability where the system improperly follows symbolic links without adequate validation. A local high-privileged attacker could exploit this to cause denial of service through file overwrite/denial, or manipulate information by redirecting file operations to unintended locations.

MitigationApply the vendor patch for CVE-2024-25953 when available. Until then, restrict local privileged access and monitor file system operations for suspicious symlink creation patterns.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed PowerScale OneFS version
    Run 'isi version' or 'isi status' command to retrieve the OneFS version number
    Affected if The version falls within 9.4.0.0-9.4.0.16, 9.5.0.0-9.5.0.7, or 9.6.1.0-9.7.0.1
  2. Check for high-privileged local users
    Review local user accounts with elevated privileges using 'isi auth' commands or check /var/db/root directory for unauthorized privileged accounts
    Affected if Untrusted or unauthorized users have been granted high-privileged access to the system
  3. Audit filesystem for suspicious symlinks
    Use 'find / -type l -ls' to list all symbolic links on the system, particularly in /ifs and config directories
    Affected if Symbolic links are found pointing to sensitive system files or directories outside expected paths
  4. Review symlink creation timestamps
    Check creation times of recent symlinks using 'ls -laR /ifs' focusing on unusual recent modifications
    Affected if Multiple symlinks were created recently in system directories by privileged users
  5. Inspect audit logs for symlink-related file operations
    Review OneFS audit logs (isi audit) for file operations that may have followed symlinks to unintended locations
    Affected if Logs show file operations unexpectedly targeting files outside the intended directory scope

A system is affected if it runs PowerScale OneFS version 9.4.0.0-9.4.0.16, 9.5.0.0-9.5.0.7, or 9.6.1.0-9.7.0.1 and has untrusted high-privileged local users or suspicious symlink activity present.

Upgrade available Upgrade to 9.5.0.8 / 9.7.0.2 or later
Fixed in 9.5.0.89.7.0.2
Interim mitigation

Apply the vendor patch for CVE-2024-25953 when available. Until then, restrict local privileged access and monitor file system operations for suspicious symlink creation patterns.

Recommended fix Moderate confidence

OneFS 9.7.0.2 or later (or 9.5.0.8+ for respective branches)

  1. Review the current PowerScale OneFS version using 'isi version' or through the web admin console
  2. Determine the current major version line (9.4.0.x, 9.5.0.x, or 9.6.1+/9.7.0.x)
  3. For versions 9.4.0 through 9.4.0.16: upgrade to OneFS 9.5.0.8 or later, or 9.7.0.2 or later
  4. For versions 9.5.0.0 through 9.5.0.7: upgrade to OneFS 9.5.0.8 or later
  5. For versions 9.6.1 through 9.7.0.1: upgrade to OneFS 9.7.0.2 or later
  6. Download the upgrade ISO from Dell support portal (support.dell.com)
  7. Follow standard OneFS upgrade procedure: run 'isi upgrade' or use SmartUpgrade via the web interface
  8. Verify the upgrade completed successfully with 'isi version'
