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
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
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
Low
A
There is reduced performance or interruptions in resource availability. However, the attacker does not have the ability to completely prevent access to the resources or services; the impact is limited.

## Title: Senayan Library Management System v9.1.1 a.k.a SLIMS 9 XSS-Reflected - PHPSESSID Hijacking + inserting webp image
## Author: nu11secur1ty
## Date: 12.17.2022
## Vendor: https://slims.web.id/web/
## Software: https://github.com/slims/slims9_bulian/releases/tag/v9.1.1
## Reference: https://github.com/nu11secur1ty/CVE-nu11secur1ty/tree/main/vendors/slims.web.id/SLIMS-9.1.1
## Description:
The value of the `class` request parameter is copied into the HTML
document as plain text between tags.
The payload ytrrh<script>alert(1)</script>z3nj2 was submitted in the
class parameter. This input was echoed unmodified in the application's
response.
The attacker can trick some authenticated user to visit his page and
give to him very sensitive information about the system.
