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
Low
PR
The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
Scope
Unchanged
S
An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
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.

Threat: Hades RAT - Web Panel
Vulnerability: Remote Persistent XSS
Family: Hades
Type: WebUI
MD5: c4cc1317aea42f7dd4a1b786c5278a24
MD5: d1d082cbb2a394c8974e734e2ad9f226 (index.php)
Vuln ID: MVID-2022-0514
Disclosure: 03/13/2022
Description: The Hades Rat web-panel listens on Port 80, it takes three HTTP Post parameters to write bot commands. Commands are written to three files: commande1.txt, commande2.txt and commande3.txt. The index.php file does not follow secure coding practices e.g. no sanitizing of input. Third-party attackers who can authenticate to the Hades server, can make HTTP Post requests writing arbitrary JS code into the commande1.txt file. The XSS payload will execute client side code in the security context of the currently logged on user anytime the WebUI is accessed. This can result in data modification, theft or GEO location disclosure of the user accessing the Hades Rat WebUI.
