Content

VULNERABILITY DETAILS:
CVE ID:
CVE-2013-0531

DESCRIPTION:
The AppScan Enterprise server supports SSL cipher suites that use weak encryption algorithms. An attacker may therefore be able to decrypt the secure communication between the client and the server, or successfully execute a "man-in-the-middle" attack on the client, enabling them to view sensitive information and perform actions on behalf of the client.

The attack does not require local network access nor does it require authentication, but some degree of specialized knowledge and techniques are required. An exploit would not impact the confidentiality of information or the availability of the system, but the integrity of the data could be compromised.

CVE ID:
CVE-2013-2997

DESCRIPTION:
Logging out of the AppScan Enterprise application does not invalidate current session values. This could lead to other users employing those identifiers to impersonate that user and perform actions on their behalf.

The attack does not require specialized knowledge or techniques, but local network access and authentication are required. An exploit would not impact the availability of the system or the integrity of data, but the confidentiality of information could be compromised.
