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.

Weakness

The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files.

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.
