Security Bulletin: TSM Client Scheduler Denial Of Service Vulnerability (CVE-2013-0471)

Flash (Alert)


A Denial of Service vulnerability exists in the IBM Tivoli Storage Manager (TSM) client traditional scheduler


DESCRIPTION: A Denial of Service vulnerability in the TSM client traditional scheduler allows a remote attacker to disable the traditional scheduler when it is in Prompted mode (SCHEDMODE=PROMPTED). Once disabled, no more schedules (such as scheduled backups) will be run, and the TSM server log will show that schedules for that node are missed.

One of the following:
  • If using the traditional scheduler, set the SCHEDMODE option value to POLLING, which is the default value, in the client options file or on the command line
  • Configure the scheduler to be managed by Client Acceptor Daemon (CAD), by specifying 'MANAGEDSERVICES SCHEDULE' or 'MANAGEDSERVICES SCHEDULE WEBCLIENT' in the client options file
