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.
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	Low	C	There is some impact on confidentiality, but the attacker either does not gain control of any data, or the information obtained does not have a significant impact on the system or its operations.
Integrity	Low	I	Modification of data is possible, but the attacker does not have control over what can be modified, or the extent of what the attacker can affect is limited. The data modified does not have a direct, serious impact on the system.
Availability	None	A	There is no impact on the availability of the system; the attacker does not have the ability to disrupt access to or use of the system.

Mambo CMS 4.6.x (4.6.5) | Multiple Cross Site Scripting Vulnerabilities 1. OVERVIEW Mambo CMS 4.6.5 and lower versions are vulnerable to Cross Site Scripting. 2. BACKGROUND Mambo is a full-featured, award-winning content management system that can be used for everything from simple websites to complex corporate applications. It is used all over the world to power government portals, corporate intranets and extranets, ecommerce sites, nonprofit outreach, schools, church, and community sites. Mambo's "power in simplicity" also makes it the CMS of choice for many small businesses and personal sites. 3. VULNERABILITY DESCRIPTION Multiple parameters (task, menu, menutype, zorder, search, client, section) are not properly sanitized, which allows attacker to conduct Cross Site Scripting attack. This may allow an attacker to create a specially crafted URL that would execute arbitrary script code in a victim's browser. 4. VERSIONS AFFECTED Tested on Mambo CMS 4.6.5 (current as of 2011-06-27) 5.
