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
Low
C
There is some impact on confidentiality, but the attacker either does not gain control of any data, or the information obtained does not have a significant impact on the system or its operations.
Integrity
Low
I
Modification of data is possible, but the attacker does not have control over what can be modified, or the extent of what the attacker can affect is limited. The data modified does not have a direct, serious impact on the system.
Availability
None
A
There is no impact on the availability of the system; the attacker does not have the ability to disrupt access to or use of the system.

Technical Details & Description:
================================
A non-persistent cross site scripting vulnerability has been discovered in the official Tiny MySQL console web-application.
The vulnerability allows remote attackers to inject own malicious script codes with non-persistent attack vector to
compromise browser to web-application requests from the client-side.
The cross site scripting vulnerabilities are located in the `table` parameter of the `tinymy.php` file. The request method
to inject the malicious script code is GET and the attack vector of the vulnerability is non-persistent on client-side.
Successful exploitation of the vulnerability results in session hijacking, non-persistent phishing attacks, non-persistent external
redirects to malicious source and non-persistent manipulation of affected application modules.
Request Method(s):
[+] GET
Vulnerable Parameter(s):
[+] table
Proof of Concept (PoC):
=======================
The non-persistent web vulnerability can be exploited by remote attackers without user account with low user interaction.
For security demonstration or to reproduce the vulnerability follow the provided information and steps below to continue.
PoC: Example
https://localhost:8080/tinymy/tinymy.php?act=sel_table&table=<[NON-PERSISTENT CROSS SITE SCRIPTING!]>
PoC: Exploitation
