Metrics

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 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.

On v7 the url has to be prepended with /event/. Affected versions: all versions from v7 to v9.9 build 9002. GET /hostdetails?slid=X&hostid=Y GET /hostdetails?slid=1&hostid=1 --> Windows / AS/400 hosts superuser username and password (XOR'ed with 0x30 and base64 encoded) A Metasploit exploit that abuses these two vulnerabilities to obtain the managed device superuser credentials has been released. >> Fix: UNFIXED - ManageEngine failed to take action after 70 days. Timeline of disclosure: 28/08/2014 - Requested contact to email via ManageEngine Security Response Center - Received email from support and sent details about the vulnerabilities above and a third vulnerability (remote code execution via file upload). 28/08/2014 - ManageEngine acknowledge the receipt and promise to keep me informed of the progress. 31/08/2014 - hong10 releases details about the remote code execution via file upload vulnerability which I had discovered. Apparently he discovered and communicated it to ManageEngine over a year ago and no action had been taken (see http://seclists.org/fulldisclosure/2014/Aug/86). - I ask ManageEngine why I hadn't been informed that one of my vulnerabilities had already been disclosed to them over a year ago. They respond with "We appreciate your efforts and will fix your vulnerabilities, please bear with us". - With hong10's support, I release an exploit for the remote code execution vulnerability (see http://seclists.org/fulldisclosure/2014/Aug/88). I also remove the vulnerability information from this report since it has already been discovered and disclosed by hong10. 11/09/2014 - Asked for an update on progress. Received a response a day after "the development team will include the fix in our next release". 13/10/2014 - Asked for an update on progress. No response. 17/10/2014 - Informed ManageEngine that will release details and an exploit the next day if no reply is received. 19/10/2014 - Attempted escalation via the project manager for Desktop Central. EventLog support team replies on the next day apologising for not responding and saying will get back to me as soon as possible. 05/11/2014 - Informed EventLog support that would release details and exploit today. Received reply stating "we are working on this but cannot commit to a date; the new version has a tentative release date of end of quarter". - Released advisory and exploit 70 days after initial contact (interesting fact: it's been 67 days since the release of my exploit for hong10's vulnerability and EventLog Analyzer is still vulnerable to remote code execution). ================ Agile Information Security Limited http://www.agileinfosec.co.uk/ >> Enabling secure digital business >>
