Dell PowerScale OneFS versions 8.2.2.x through 9.8.0.1 contains a UNIX symbolic link (symlink) following vulnerability. A local high privileged attacker could potentially exploit this vulnerability, leading to denial of service, information tampering.

Weakness

The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

Affected Software

Name Vendor Start Version End Version
Powerscale_onefs Dell 8.2.2.0 (including) 9.7.1.2 (excluding)
Powerscale_onefs Dell 9.8.0.0 (including) 9.8.0.0 (including)

Potential Mitigations

  • Follow the principle of least privilege when assigning access rights to entities in a software system.
  • Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
