Métriques

V3.1 5.3 MEDIUM CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/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.

None

There is no loss of confidentiality within the impacted component.

Integrity Impact

This metric measures the impact to integrity of a successfully exploited vulnerability. Integrity refers to the trustworthiness and veracity of information.

Low

Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on 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.

# Title: Adobe Connect 11.4.5 - Local File Disclosure # Author: h4shur # date:2021.01.16-2023.02.17 # CVE: CVE-2023-22232 # Vendor Homepage: https://www.adobe.com # Software Link: https://www.adobe.com/products/adobeconnect.html # Version: 11.4.5 and earlier, 12.1.5 and earlier # User interaction: None # Tested on: Windows 10 & Google Chrome, kali linux & firefox ### Summary: Adobe Connect versions 11.4.5 (and earlier), 12.1.5 (and earlier) are affected by an Improper Access Control vulnerability that could result in a Security feature bypass. An attacker could leverage this vulnerability to impact the integrity of a minor feature. Exploitation of this issue does not require user interaction. ### Description : There are many web applications in the world, each of which has vulnerabilities due to developer errors, and this is a problem for all of them, and even the best of them, like the "adobe connect" program, have vulnerabilities that occur every month. They are found and fixed by the team. * What is LFD bug? LFD bug stands for Local File Disclosure / Download, which generally allows the attacker to read and download files within the server, so it can be considered a very dangerous bug in the web world and programmers must be aware of it. Be careful and maintain security against this bug * Intruder access level with LFD bug The level of access using this bug can be even increased to the level of access to the website database in such a way that the hacker reads sensitive files inside the server that contain database entry information and enters the database and by extracting the information The admin will have a high level of access * Identify vulnerable sites To search for LFD bugs, you should check the site inputs. If there is no problem with receiving ./ characters, you can do the test to read the files inside the server if they are vulnerable. Enter it and see if it is read or not, or you can use files inside the server such as / etc / passwd / .. and step by step using ../ to return to the previous path to find the passwd file * And this time the "lfd" in "adobe connect" bug: To download and exploit files, you must type the file path in the "download-url" variable and the file name and extension in the "name" variable. You can download the file by writing the file path and file name and extension. When you have written the file path, file name and extension in the site address variables, a download page from Adobe Connect will open for you, with "Save to My Computer file name]" written in the download box and a file download link at the bottom of the download box, so you can download the file. * There are values inside the url that do not allow a file other than this file to be downloaded. * Values: sco_id and tickets But if these values are cleared, you will see that reloading is possible without any obstacles At another address, you can download multiple files as a zip file. We put the address of the files in front of the variable "ffn" and if we want to add the file, we add the variable "ffn" again and put the address of the file in front of it. The "download_type" variable is also used to specify the zip extension. ### POC : https://target.com/[folder]/download?download-url=[URL]&name=[file.type] https://target.com/[folder]/download?output=output&download_type=[Suffix]&ffn=[URL]&baseContentUrl=[base file folder] ### References: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-22232 https://nvd.nist.gov/vuln/detail/CVE-2023-22232 https://helpx.adobe.com/security/products/connect/apsb23-05.html
