Authenticated service interruption via unbounded table generation
Published Nov 20, 2024 · Updated Dec 3, 2024
Resource-exhaustion DoS in eSoft Planner 3.24.08271-USA allows remote authenticated users to interrupt service via a crafted POST request. The Instructor Appointment Availability handler accepts a quoted date10_month value, falls back to 1970, and builds an hourly HTML table through the present without an effective output limit. A tenant access key is required, and instructor counts and appointment types control response size; interruption beyond the requesting user remains unconfirmed.
