Security readout for executives and security teams
This CVE describes a legacy IBM AIX Navio NC configuration script that exports /tmp over NFS as world-readable and world-writable. That can expose temporary files and allow remote network users to write into a shared temporary directory. The issue matters mainly where old Navio NC-related software still exists. Exposure is likely limited to legacy IBM AIX systems that installed or retained netstation.navio-com.rte 1.1.0.1 for Navio NC. Modern environments are unlikely to be affected unless old AIX network computer support packages or inherited NFS exports remain in service. Prioritize this if legacy AIX systems are still operating in sensitive or flat networks. It is not currently evidenced as actively exploited, but world-writable NFS exposure can create avoidable data exposure and tampering risk. Mitigation focus: Inventory AIX hosts for netstation.navio-com.rte 1.1.0.1 or Navio NC remnants.; Review NFS exports and remove any broad /tmp export.; Restrict NFS access to explicitly required hosts and least-privilege permissions..
