Informations du CVE

Faiblesses connexes

CWE-ID Nom de la faiblesse Source
CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

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.

Low

The attacker is authorized with (i.e. requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.

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.

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 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.

SEC Consult Vulnerability Lab Security Advisory < 20180813-0 > ======================================================================= title: SQL Injection, XSS & CSRF vulnerabilities product: Pimcore vulnerable version: 5.2.3 and below fixed version: 5.3.0 CVE number: CVE-2018-14057, CVE-2018-14058, CVE-2018-14059 impact: High homepage: https://pimcore.com/en found: 2018-06-11 by: T. Silpavarangkura (Office Bangkok) N. Rai-Ngoen (Office Bangkok) SEC Consult Vulnerability Lab An integrated part of SEC Consult Europe | Asia | North America https://www.sec-consult.com ======================================================================= Vendor description: ------------------- "Pimcore is an award-winning consolidated open source enterprise platform for master data management (PIM/MDM), user experience management (CMS/UX), digital asset management (DAM) and eCommerce." Source: https://pimcore.com/en Business recommendation: ------------------------ The vendor provides a patch for most identified issues, but XSS will not be fixed according to the vendor. An in-depth security analysis performed by security professionals is highly advised, as the software may be affected from further security issues. Vulnerability overview/description: ----------------------------------- 1. SQL Injection (CVE-2018-14058) Multiple SQL injection vulnerabilities have been identified in the REST web service API. An attacker who obtains a valid API key that is granted a necessary permission could successfully perform an attack to extract information from the database. 2. Stored Cross-site Scripting (CVE-2018-14059) Multiple stored cross-site scripting vulnerabilities have been identified across multiple functions in the application, which allows an authenticated attacker to insert arbitrary JavaScript code in virtually all text fields and data entries in the application. 3. Cross-site Request Forgery (CVE-2018-14057) Multiple functions in the application are not protected by the existing anti-CSRF token, which allows an attacker to perform a cross-site request forgery attack to at least add, update or delete entries, among other actions. Proof of concept: ----------------- 1. SQL Injection (CVE-2018-14058) The following URLs demonstrate the issue: http://<host>/webservice/rest/asset-count?apikey=[...]&condition=<SQL Injection> http://<host>/webservice/rest/asset-inquire?apikey=[...]&id=<SQL Injection> http://<host>/webservice/rest/asset-list?apikey=[...]&condition=<SQL Injection> http://<host>/webservice/rest/document-count?apikey=[...]&condition=<SQL Injection> http://<host>/webservice/rest/document-inquire?apikey=[...]&id=<SQL Injection> http://<host>/webservice/rest/document-list?apikey=[...]&condition=<SQL Injection> http://<host>/webservice/rest/object-count?apikey=[...]&condition=<SQL Injection> http://<host>/webservice/rest/object-inquire?apikey=[...]&id=<SQL Injection> http://<host>/webservice/rest/object-list?apikey=[...]&condition=<SQL Injection> Note that a valid API key that is granted at least either "Assets", "Documents" or "Objects" permission is required to perform an SQL injection attack against associated API endpoints successfully. 2. Stored Cross-site Scripting (CVE-2018-14059) Most of the text fields in pop-up dialogs and data entries in the application are vulnerable to the cross-site scripting vulnerability, which can be exploited by an authenticated attacker. For example, the attacker could insert an attack payload while performing at least the following actions: 1) Edit a user account's first name/last name/e-mail address. 2) Edit a Document Types/Predefined Properties/Predefined Asset Metadata/ Quantity Value/Static Routes entry value in the table. 3) Rename an Assets/Data Objects/Video Thumbnails/Image Thumbnails/ Field-Collections/Objectbrick/Classification Store item. The vendor stated that many identified XSS issues only affect administrative functions and hence the issues will not be fixed: "They are only affecting administrative functionalities (higher privileges required) - so this isn't used by non-trusted users - a check just adds additional overhead without any benefits for security." SEC Consult argued multiple times that XSS can still be exploited e.g. when a higher privileged user gets attacked and the issues should be fixed nevertheless. 3. Cross-site Request Forgery (CVE-2018-14057) The existing anti-CSRF token in the HTTP request header named "X-pimcore-csrf-token" was found to be validated only in the "Settings > Users / Roles" function. Therefore, an attacker could perform a cross-site request forgery attack against virtually all other functions in order to at least add, update and delete data without having to submit the anti-CSRF token. The non-exhaustive list of affected requests are listed below: POST /admin/asset/add-asset POST /admin/asset/add-asset-compatibility GET /admin/asset/delete GET /admin/asset/import-server GET /admin/asset/import-server-files GET /admin/asset/import-url POST /admin/asset/import-zip POST /admin/asset/update GET /admin/document/add GET /admin/document/delete POST /admin/document/doc-types POST /admin/email/blacklist POST /admin/email/email-logs POST /admin/email/save POST /admin/hardlink/save POST /admin/link/save POST /admin/newsletter/save GET /admin/object/add POST /admin/object/save GET /admin/object/delete POST /admin/page/save POST /admin/settings/metadata POST /admin/settings/properties POST /admin/settings/set-system POST /admin/settings/website-settings POST /admin/snippet/save Vulnerable / tested versions: ----------------------------- The vulnerabilities have been identified in Pimcore version 5.2.3 which was the most current version at the time of discovery. Vendor contact timeline: ------------------------ 2018-06-15: Contacting vendor through https://pimcorehq.wufoo.com/forms/pimcore-security-report 2018-06-18: Vendor provides the fixes of SQL injection and CSRF in the nightly build, but has a problem of reproducing the XSS. 2018-06-18: Contacting vendor to request for a secure channel to provide further details of the XSS. 2018-06-18: Sending the details of the XSS. 2018-06-19: Vendor fixes the SQL injection and only fixes the XSS partially. 2018-06-20: Notifying vendor, that SQL injection and XSS are not properly fixed 2018-06-20: Vendor inquires more details about the XSS. 2018-06-21: Explaining vendor the XSS issues and notifying vendor that the CSRF has been fixed. 2018-06-21: Vendor will discuss the open issues internally. 2018-07-11: Following up vendor regarding the fixes of the open issues. 2018-07-11: Vendor completely fixes the SQL injection, but decides not to fix the XSS in the administrative functions, patch release is planned within the next two weeks 2018-07-20: Vendor provides a patched version 2018-08-13: Public release of security advisory Solution: --------- The vendor has published a new release (version 5.3.0) which fixes most of the identified issues, but not the XSS issues that affect administrative functions: https://pimcore.com/en/download Workaround: ----------- None Advisory URL: ------------- https://www.sec-consult.com/en/vulnerability-lab/advisories/index.html ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ SEC Consult Vulnerability Lab SEC Consult Europe | Asia | North America About SEC Consult Vulnerability Lab The SEC Consult Vulnerability Lab is an integrated part of SEC Consult.
