Technical details
An improper privilege management flaw in the VxWorks 7 command shell (CWE-269) permits authenticated users with restricted privileges to execute commands that should be blocked by privilege checks. The vulnerability arises when the OS is configured to enforce per-user command privileges; under specific shell operations, the privilege validation is bypassed. No special network access or user interaction is required beyond initial authentication; the attacker gains elevated execution capabilities on the device.
