The (1) bin/invscoutClient_VPD_Survey and (2) sbin/invscout_lsvpd programs in invscout.rte before 2.2.0.19 on IBM AIX 7.1, 6.1, 5.3, and earlier allow local users to delete arbitrary files, or trigger inventory scout operations on arbitrary files, via a symlink attack on an unspecified file.

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.

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.
