Abstract
User/Group security vulnerability in uninstaller JRE for IBM WebSphere Message
Broker, MBX and SupportPacs IE02 and IS02 Content
VULNERABILITY DETAILS
CVE ID: CVE-2012-3317
DESCRIPTION:
When the WebSphere Message Broker, MBX, IE02 and IS02 uninstaller
IBM Java Runtime Environment (JRE) files are created, they are not owned by
the same user and group as the other product files. This ownership may not
resolve to a trusted user on every system, and gives that user the ability to
change program files which will later be run by the root user. The JRE files
should be owned by the same user as other installed WebSphere Message Broker,
MBX, IE02 and IS02 files.
CVSS:
CVSS base score: 6.9
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/77818 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:M/Au:N/C:C/I:C/A:C)
*The CVSS Environment Score is customer environment specific and will
ultimately impact the Overall CVSS Score. Customers can evaluate the impact of
