CVSS vector description

Metric	Value	Metric Description	Value Description
Attack vector	Network	AV	The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity	Low	AC	The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required	None	PR	The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction	None	UI	The vulnerable system can be exploited without interaction from any human user, other than the attacker. Examples include: a remote attacker is able to send packets to a target system a locally authenticated attacker executes code to elevate privileges
Scope	Unchanged	S	An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality	High	C	There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity	High	I	There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file on the target system.
Availability	High	A	There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.

|| || [ISR] || Infobyte Security Research || www.infobyte.com.ar || 09.27.2005 || .:: SUMMARY Novell GroupWise Client Integer Overflow Version: GroupWise 6.5.3, It is suspected that all previous versions of Groupwise Client are vulnerable. .:: BACKGROUND GroupWise Client is Novell's premier Intranet/Internet GroupWare solution for platform Windows. More info: http://www.novell.com .:: DESCRIPTION This issue is due to a failure of the application to securely parse the saved port number of the last authentication store in windows register. To reproduce this, we have to modify the default register key of HKEY_CURRENT_USERSoftwareNovellGroupWiseLogin ParametersTCP/IP Port For example, set the value (11111111111111111111111111111111). Then, when we open the application client and the client get the port information occur the integer overflow.
