SAP FRUN Simple Diagnostics Agent 1.0 Missing Authentication

`# Onapsis Security Advisory 2022-0004: Missing Authentication check in SAP  
Focused Run (Simple Diagnostics Agent 1.0)  
  
  
## Impact on Business  
  
Because the Simple Diagnostic Agent (SDA) handles several important  
configuration and critical credential information, a successful attack  
could lead to the control of the SDA, and therefore affect:  
* Integrity, by modifying the configuration.  
* Availability, by stopping the service.  
* Confidentiality and Scope changing, by decrypting all stored  
credentials. Then  
accessing the SAP Focused Run system as well as the SAP system managed by  
the  
SDA.

## Vulnerability Details  
  
Vulnerability 1:  
  
No authentication is required to interact with the Simple Diagnostic Agent  
http  
service on port 3005 by default. Therefore, unauthenticated attackers will  
have  
full access to either administrative or other privileged functionalities.  
Leveraging  
this access, they would be able to read, modify or delete sensitive  
information and  
configurations with sapadm OS user privileges.  
  
Vulnerability 2:  
  
A path traversal exists in the Simple Diagnostic Agent service listening, by  
default, on localhost port 3005. A local attacker, without particular  
privileges,  
can abuse this flaw in order to display the content of any OS directory  
which ```sapadm```  
has access to. Leading to information disclosure of potentially sensitive  
data.  
  
  
  
## Solution  
  
SAP has released SAP Note 3145987 which provide patched versions of the  
affected components.  
  
The patches can be downloaded from  
https://launchpad.support.sap.com/#/notes/3145987.  
  
Onapsis strongly recommends SAP customers to download the related  
security fixes and apply them to the affected components in order to  
reduce business risks.
