Base: Exploitabilty Metrics

The Exploitability metrics reflect the characteristics of the thing that is vulnerable, which we refer to formally as the vulnerable component.

Attack Vector

This metric reflects the context by which vulnerability exploitation is possible.

Network

The vulnerable component 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).

Attack Complexity

This metric describes the conditions beyond the attacker’s control that must exist in order to exploit the vulnerability.

Low

Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success when attacking the vulnerable component.

Privileges Required

This metric describes the level of privileges an attacker must possess before successfully exploiting the vulnerability.

None

The attacker is unauthorized 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

This metric captures the requirement for a human user, other than the attacker, to participate in the successful compromise of the vulnerable component.

Required

Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited. For example, a successful exploit may only be possible during the installation of an application by a system administrator.

Base: Scope Metrics

The Scope metric captures whether a vulnerability in one vulnerable component impacts resources in components beyond its security scope.

Scope

Formally, a security authority is a mechanism (e.g., an application, an operating system, firmware, a sandbox environment) that defines and enforces access control in terms of how certain subjects/actors (e.g., human users, processes) can access certain restricted objects/resources (e.g., files, CPU, memory) in a controlled manner. All the subjects and objects under the jurisdiction of a single security authority are considered to be under one security scope. If a vulnerability in a vulnerable component can affect a component which is in a different security scope than the vulnerable component, a Scope change occurs. Intuitively, whenever the impact of a vulnerability breaches a security/trust boundary and impacts components outside the security scope in which vulnerable component resides, a Scope change occurs.

Unchanged

An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.

Base: Impact Metrics

The Impact metrics capture the effects of a successfully exploited vulnerability on the component that suffers the worst outcome that is most directly and predictably associated with the attack. Analysts should constrain impacts to a reasonable, final outcome which they are confident an attacker is able to achieve.

Confidentiality Impact

This metric measures the impact to the confidentiality of the information resources managed by a software component due to a successfully exploited vulnerability.

High

There is a total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server.

Integrity Impact

This metric measures the impact to integrity of a successfully exploited vulnerability. Integrity refers to the trustworthiness and veracity of information.

None

There is no loss of integrity within the impacted component.

Availability Impact

This metric measures the impact to the availability of the impacted component resulting from a successfully exploited vulnerability.

None

There is no impact to availability within the impacted component.

Temporal Metrics

The Temporal metrics measure the current state of exploit techniques or code availability, the existence of any patches or workarounds, or the confidence in the description of a vulnerability.

Environmental Metrics

These metrics enable the analyst to customize the CVSS score depending on the importance of the affected IT asset to a user’s organization, measured in terms of Confidentiality, Integrity, and Availability.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

HelpCenter Live! Multiple Vulnerabilities Vendor: Michael Bird Product: HelpCenter Live! Version: <= 1.2.7 Website: http://www.helpcenterlive.com/ BID: 13666 13667 CVE: CVE-2005-1672 CVE-2005-1673 CVE-2005-1674 OSVDB: 16651 16652 16653 16654 16655 16656 16657 16658 SECUNIA: 15401 PACKETSTORM: 39275 Description: Help Center Live is a `Live` help desk system written in PHP using a MySql database backend that features Live Support, Trouble Tickets and FAQ within one project. This is a very popular application, especially with webhosts and other services. Unfortunately Help Center Live is vulnerable to Sql injection, Script Injection, and Cross Site Scripting attacks, but the most serious of the vulnerabilities mentioned (The SQL Injection attacks) require magic_quotes_gpc to be set to off. Cross Site Scripting: Cross site scripting exists in Help Center Live. This vulnerability exists due to user supplied input not being checked properly. Below is an example. http://path/faq/index.php?find=blah[CODEGOESHERE]&search=Search This vulnerability could be used to steal cookie based authentication credentials within the scope of the current domain, or render hostile code in a victim's browser. This is the same vulnerability I had reported in my previous Help Center Live advisory, but it seems that the issue was never resolved properly. Script Injection Vulnerability: There are several script injection vulnerabilities in Help Center Live that allows an attacker to force a logged in operator to run malicious code in their browser. This can be accomplished by an attacker by entering malicious code into the name or message fields when requesting a chat, or by entering malicious script into the body of a message when opening a trouble ticket. Also, an attacker can use this to retrieve the md5 password of the operator (the md5 password is stored in the cookie), or can use this issue combined with the soon to be mentioned CSRF issue and force an admin to unknowingly or knowingly execute arbitrary commands. Cross Site Request Forgeries: Help Center Live uses the GET method for some admin actions, and the only check is if the admin is logged in. This makes it easy for an attacker to trick a logged in admin to perform arbitrary requests. http://www.example.com/support/cp/tt/view.php?attach=y&tid=2 http://www.example.com/support/cp/tt/view.php?tid=2&delete=1 The above url's will (a) cause an operator to allow attachments for a trouble ticket that is opened with the id of two (b) cause an operator to delete an attachment. There may be more instances of CSRF in Help Center Live, but I will leave that for someone else to mess with :) For more information on CSRF visit the following url: http://www.tux.org/~peterw/csrf.txt SQL Injection: There are a number of SQL Injection vulnerabilities in Help Center Live, as little/no sanitation is made on incoming variables passed to the SQL Query. In my opinion the only reason these issues have not been found already is because (a) everything is encapsulated in single quotes, so if magic quotes gpc is on then we cannot exploit the issues (b) Every single SQL Injection issue I am about to talk about is a somewhat blind SQL Injection issue. First we have a couple "run of the mill" SQL Injection issues in tt/view.php and faq/index.php respectively. I will not spend a lot of time on the technical details of these issues because they are nothing we have not seen a million times. Here is some vulnerable code snip though to give an understanding. $TICKET_tid = $_GET["tid"]; $result = DATABASE_query("SELECT * FROM ".$DB_prefix."tickets WHERE id='$TICKET_tid' AND username='$TICKETS_username'"); if ($get = DATABASE_fetch($result)) { As we can see from the above code $TICKET_tid is never sanitized and taken directly from the user supplied $_GET. We cannot exploit this issue, or any other issue in this advisory because the data is encapsulated in single quotes, and magic_quotes_gpc will not allow us to break the query. Below are example requests that will allow for us to grab an operators username and password hash by exploiting the above code, and also very similar code in /faq/index.php http://www.example.com/support/faq/index.php?x=f&id=-99'%20UNION%20SELECT%200, 0,operator,password%20FROM%20hcl_operators%20WHERE%201/* http://www.example.com/support/tt/view.php?tid=-99'%20UNION%20SELECT%200,0,0, operator,password,0,0,0,0,0%20FROM%20hcl_operators%20WHERE%201/* There are also a few more SQL Injection vulnerabilities in Help Center Live that are a bit more interesting, and these issues lie in lh/chat_download.php, lh/icon.php, and tt/download.php. I find these particular examples a bit more interesting because they are download scripts, and successful exploitation leads to things like the downloaded file having the desired password hash, the content type in the headers displaying the hash, or having a base64_decoded version of the hash that may look something like this (‡íÞ÷á¯=Ùî7}ÿ7�×uõíÛkN¹) but can be base64 encoded into the md5 hash. http://www.example.com/support/tt/download.php?fid=-99'%20UNION%20SELECT%200,0,0, password,0,operator,0,0%20FROM%20hcl_operators%20WHERE%20id='1 http://www.example.com/support/lh/icon.php?status=-99' UNION SELECT password, password FROM hcl_operators WHERE id=1/* http://www.example.com/support/lh/chat_download.php?fid=-99' UNION SELECT password, operator,password FROM hcl_operators WHERE id=1/* Again, exploitation of these issues requires magic_quotes_gpc set to off on the server hosting the Help Center Live installation. Solution: According to the develepor a patch has been available for some time now. Credits: James Bercegay of the GulfTech Security Research Team
