  • Probability of exploitation in the next 30 days: 0.76% (FIRST EPSS); higher than 54.8% of all records.
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Dell Wyse Management Suite (WMS) 2605.0.2.

Low priority for now. Upgrade to Dell Wyse Management Suite (WMS) 2605.0.2 or later.
