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

Flashes (Alerts)


Abstract

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

Content

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.

CVEID: CVE-2013-0471
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/81215
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)
