Document information
Security AppScan Enterprise
News
Software version:
8.5, 8.6, 8.7.0.0, 8.7.0.1
Operating system(s):
Windows
Reference #:

Modified date:
2013-10-22
Abstract
Previous releases of IBM Security AppScan Enterprise are affected by multiple
vulnerabilities reported in 3rd party components bundled with the product as
well as in proprietary IBM code. These vulnerabilities include weak cipher
suites, invalid certificate warnings and URL spoofing.
Content
VULNERABILITY DETAILS:
CVE ID:
CVE-2013-4062
DESCRIPTION:
An invalid certificate warning is not displayed when secure http traffic is
intercepted. This may allow an attacker to successfully execute a
"man-in-the-middle" attack on the client.
The attack requires local network access, does not require authentication,
but a high degree of specialized knowledge and techniques are required. An
exploit would impact the confidentiality of information, the integrity of
data and the availability of the system could be compromised.
CVSS:
CVSS Base Score: 3.7
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/86586 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:H/Au:N/C:P/I:P/A:P)
AFFECTED PLATFORMS:
Running on Microsoft Windows:
- - Version 8.5 through 8.7 of Security AppScan Enterprise
REMEDIATION:
The recommended solution is to apply the fix for each named product as soon as
practical. Please see below for information about the fixes available.
Vendor Fix(es):
For version 8.5 to 8.7 of AppScan Enterprise
- - Upgrade to version 8.8
If you are unable to upgrade, contact IBM Technical Support.
If you are using your own certificate, makes sure that you add it the IBM
certificate trust store so that it will be accepted successfully.
Workaround(s):
Not applicable; upgrade to version 8.8 for AppScan Enterprise
Mitigation(s):
Vulnerability does not exist when AppScan Enterprise is configured to use
Windows Authentication.
CVE ID:
CVE-2013-4061
DESCRIPTION:
Unauthorized users have the ability able to update allowed hosts used for
authentication. This can be used to facilitate spoofing through URL
redirection.
The attack does not require local network access but does require single
authentication. A high degree of specialized knowledge and techniques are
required to exploit this issue. An exploit would not impact the availability
of the system or the integrity of data, but the confidentiality of information
could be compromised.
CVSS:
CVSS Base Score: 2.1
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/86585 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:S/C:P/I:N/A:N)
AFFECTED PLATFORMS:
Running on Microsoft Windows:
- - Version 8.5 through 8.7 of Security AppScan Enterprise
REMEDIATION:
The recommended solution is to apply the fix for each named product as soon
as practical. Please see below for information about the fixes available.
Vendor Fix(es):
For version 8.5 to 8.7 of AppScan Enterprise
- - Upgrade to version 8.8
If you are unable to upgrade, contact IBM Technical Support.
Workaround(s):
Not applicable; upgrade to version 8.8 of AppScan Enterprise
Mitigation(s):
Vulnerability does not exist when AppScan Enterprise is configured to use
Windows Authentication.
CVE ID:
CVE-2013-5430
DESCRIPTION:
It is possible to install the Jazz Team Server component and have it enabled
and configured with the default username and password. This could allow an
unauthorized user to obtain access to the Jazz Team server component.
The attack does not require specialized knowledge or techniques, nor does it
require authentication, and network access required. An exploit could impact
the confidentiality of information and the availability of the system, but
the integrity of data is not compromised.
CVSS:
CVSS Base Score: 5.5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/87562 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:S/C:P/I:P/A:N)

- - Upgrade to version 8.8
If you are unable to upgrade, contact IBM Technical Support.
Workaround(s):
Not applicable; upgrade to version 8.8 of AppScan Enterprise
Mitigation(s):
For previous versions, when configuring installation, login to the Jazz Team
Server component and either disable the admin account or change the default
password value.
CVE ID:
CVE-2013-3989
DESCRIPTION:
The password value for the AppScan Source database is sent in a response from
AppScan Enterprise in a non-encrypted format. This may allow an attacker to
successfully execute a "man-in-the-middle" attack on the client.
The attack requires some specialized knowledge or techniques, along with
single authentication and network access. An exploit could impact the
confidentiality of information, but the integrity of data and the
availability of the system are not compromised.
