Descriptions du CVE

The FailOverHelperServlet (aka FailServlet) servlet in ZOHO ManageEngine Applications Manager before 11.9 build 11912, OpManager 8 through 11.5 build 11400, and IT360 10.5 and earlier does not properly restrict access, which allows remote attackers and remote authenticated users to (1) read arbitrary files via the fileName parameter in a copyfile operation or (2) obtain sensitive information via a directory listing in a listdirectory operation to servlet/FailOverHelperServlet.

Métriques

V3.1 7.5 HIGH CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/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

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.

None

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

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 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.

Agentless monitoring of your business applications enables you high ROI and low TOC. With integrated network monitoring and bandwidth utilization, quickly troubleshoot any performance related issue with your network and assign issues automatically with ITIL based ServiceDesk integration." >> Technical details: The affected servlet is the "FailOverHelperServlet" (affectionately called FailServlet). There are definitely more vulnerabilities than the ones identified below - for example it is possible to hijack the failover operation completely. The ones listed below as the easy ones to find and exploit. #1 Vulnerability: Arbitrary file download CVE-2014-7863 Constraints: unauthenticated in OpManager and AppManager; authenticated in IT360 Affected versions: ManageEngine Applications Manager v? to v11.9 b11911; ManageEngine OpManager v8 - v11.5; IT360 v? to v10.5 POST /servlet/FailOverHelperServlet?operation=copyfile&fileName=C:\\boot.ini #2 Vulnerability: Information disclosure - list all files in a directory and its children CVE-2014-7863 (same as #1) Constraints: unauthenticated in OpManager and AppManager; authenticated in IT360 Affected versions: ManageEngine Applications Manager v? to v11.9 b11911; ManageEngine OpManager v8 - v11.5; IT360 v? to v10.5 POST /servlet/FailOverHelperServlet?operation=listdirectory&rootDirectory=C:\\ #3 Vulnerability: Blind SQL injection CVE-2014-7864 Affected versions: ManageEngine OpManager v8 - v11.5; IT360 v? to v10.5 Constraints: unauthenticated in OpManager; authenticated in IT360 POST /servlet/com.adventnet.me.opmanager.servlet.FailOverHelperServlet?operation=standbyUpdateInCentral&customerName=[SQLi_1]&serverRole=[SQLi_2] POST /servlet/com.adventnet.me.opmanager.servlet.FailOverHelperServlet?operation=standbyUpdateInCentral&customerName=a')%3b+create+table+bacas+(bodas+text)%3b--+&serverRole=a >> Fix: For Applications Manager, upgrade to version 11.9 b11912. For OpManager, install the patch for v11.4 and 11.5: https://support.zoho.com/portal/manageengine/helpcenter/articles/vulnerabilities-in-failoverhelperservlet Version 11.6 will be released with the patch. These vulnerabilities remain UNFIXED in IT360. ================ Agile Information Security Limited http://www.agileinfosec.co.uk/ >> Enabling secure digital business >>
