IBM Tivoli Storage Manager traditional scheduler denial of service

tsm-scheduler-dos (81215) The risk level is classified as MediumMedium Risk


IBM Tivoli Storage Manager (TSM) is vulnerable to a denial of service. In the TSM client, a remote attacker could disable the traditional scheduler when it is in Prompted mode (SCHEDMODE=PROMPTED). Once disabled, no more schedules (such as scheduled backups) would be run and the TSM server log would show that schedules for that node are missed.
