Summary

Incorrect access control list (ACL) might occur in case of a network
retransmission, when Active Cloud Engine (ACE) is being used.

Vulnerability Details

CVEID: CVE-2014-0875
DESCRIPTION:
Active Cloud Engine (ACE) component of IBM V7000 Unified uses NFS client
operations for data transmission. ACE is used for caching data at remote
locations and providing access to data at remote sites as if it is available
locally. Where NFS packet re-transmissions occur in response to a noisy or
slow responding network, a rare condition can result in an incorrect access
control list (ACL) on a file or directory. This could further lead to an
unauthorized user having access to that file or directory. The exposure
occurs when the ACL is being managed with ACE in IBM Storwize V7000 Unified
release versions 1.3 and 1.4.
CVSS Base Score: 3.5
