Service interruption via webserver resource exhaustion
Published Apr 21, 2022 · Updated Sep 16, 2024
Denial of service in Dell iDRAC8 before 2.83.83.83 allows remote attackers to exhaust webserver resources through unauthenticated requests. The webserver fails to validate attacker-controlled input before consuming resources without adequate bounds; Dell has not disclosed the affected request handler or input field. Network access to the management interface is sufficient, and successful exploitation interrupts management service without reported data exposure or modification.
