Denial of Service Vulnerability in SAP SolMan

Impact On Business

Any authenticated user of the Solution Manager is able to either perform a Denial of Service or read sensitive information from every SMD Agent connected to the targeted SolMan.

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.

(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. 

In order to develop and upload the aforementioned scripts, a proprietary language has to be used. 

The lack of sanitization in a specific functionality provided by this proprietary language, allows a malicious user to perform path traversal attacks. Due to these scripts being executed by the EEM robots (by default, SMD Agents), the attacker could exfiltrate files containing sensitive information from the SMDAgents. Furthermore, attacks which affect the availability of some services from the SMDAgents, could be carried out by exploiting this same vulnerability.



SAP has released SAP Note #2983204 which provides patched versions of the affected components.

The patches can be downloaded from

Onapsis strongly recommends SAP customers to download the related security fixes and apply them to the affected components in order to reduce business risks.
