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.
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
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.

# Onapsis Security Advisory 2021-0011: Missing authorization check in
SolMan End-User Experience Monitoring
## Impact on Business
Any authenticated user of the Solution Manager is able to craft/upload
and execute EEM
scripts on the SMDAgents affecting its Integrity, Confidentiality and
Availability.
## Advisory Information
- Public Release Date: 06/14/2021
- Security Advisory ID: ONAPSIS-2021-0011
- Researchers: Gonzalo Roisman, Pablo Artuso
## Vulnerability Information
- Vendor: SAP
- Affected Components:
- SAP Solution Manager 7.2
(Check SAP Note #2983204 for detailed information on affected releases)
- Vulnerability Class: [CWE-862]: Missing Authorization
- CVSS v3 score: 7.6 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L)
- Risk Level: High
- Assigned CVE: CVE-2020-26830
- Vendor patch Information: SAP Security NOTE #2983204
## Affected Components Description
SAP SolMan 7.2 introduces a bunch of web services which run on top of
the SAP Java
NetWeaver stack. The affected versions have a vulnerable web service exposed.
Affected components:
* Solman 7.20
* Solman Java Stack NW 7.5
* LM-SERVICE: 1000.7.20.9.14.20200731160700
(Check SAP Note #2983204 for detailed information on affected releases)
## Vulnerability Details
The main objective of the End-user Enterprise Monitoring (EEM) app is
to upload scripts
which will mimic user actions in order to be able to automatically perform
different kinds of tests.
This process is intended to be carried out by SAP administrators who
want to monitor their
instances. However, due to a lack of authorization check, any valid
user from the Solution
Manager is able to fully utilize this application.
In other words, any valid user is able to craft its own script, upload
it and force its execution
by an SMD Agent. Some tasks that can be carried out are:
* Execution of arbitrary HTTP requests from the SMD Agent.
* Disclosure of sensitive content.
* Resource consumption of specific services.
## Solution
SAP has released SAP Note #2983204 which provide patched versions of the
affected components.
The patches can be downloaded
fromhttps://launchpad.support.sap.com/#/notes/2983204.
Onapsis strongly recommends SAP customers to download the related
security fixes and apply them to the affected components in order to
reduce business risks.
