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.
User Interaction
None
UI
The vulnerable system can be exploited without interaction from any human user, other than the attacker. Examples include: a remote attacker is able to send packets to a target system a locally authenticated attacker executes code to elevate privileges
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.

# Onapsis Security Advisory 2022-0005: Cross-Site Scripting (XSS)
vulnerability in SAP Fiori launchpad
## Impact on Business
Impact depends on the victim's privileges. In most cases, a successful
attack
allows an attacker to hijack a session, or force the victim to perform
undesired
requests in the SAP System (CSRF) as well as redirected to arbitrary web
site
(Open Redirect).

## Affected Components Description
SAP Fiori launchpad is the entry point to ABAP platform for SAP Fiori apps
on
mobile and desktop devices.
## Vulnerability Details
During the navigation in SAP Fiori Launchpad, it is possible to provide a
custom
theme name using the url parameter ```sap-theme```. This parameter has an
option to provide the path to a .css file, which it is used directly in the
page
generation. This optional input is not sufficiently sanitized, allowing an
attacker to
control and craft any kind of html payload in the page requested.
