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.

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.

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.
