IMPACT
The vendor has provided the following information regarding
the vulnerabilities:
"This Critical Patch Update contains 10 new security fixes
for Oracle Communications Applications. 8 of these
vulnerabilities may be remotely exploitable without
authentication, i.e., may be exploited over a network
without requiring user credentials." [1]
"CVE-2015-3253
9.8
AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
The supported version that is affected is 7.5. Easily
exploitable vulnerability allows unauthenticated attacker
with network access via HTTP to compromise Oracle

Communications Unified Inventory Management accessible
data." [2]
MITIGATION
Oracle states:
"Due to the threat posed by a successful attack, Oracle
strongly recommends that customers apply CPU fixes as soon
as possible. Until you apply the CPU fixes, it may be
possible to reduce the risk of successful attack by blocking
network protocols required by an attack. For attacks that
require certain privileges or access to certain packages,
removing the privileges or the ability to access the
packages from users that do not need the privileges may help
reduce the risk of successful attack. Both approaches may
break application functionality, so Oracle strongly
recommends that customers test changes on non-production
systems. Neither approach should be considered a long-term
solution as neither corrects the underlying problem." [1]
