Code injection vulnerability in IS-M-AMC, SAP security note 1596335

SAP security note 1596335, “Code Injection Vulnerability in IS-M-AMC”, is a note. Below are the symptom, SAP recommended solution and the affected software components.

Description

Symptom

IS-M-AMC contains code that permits the execution of arbitrary program code of the user’s choice. An attacker can therefore control the behavior of the system, or can potentially escalate privileges by executing malicious code, without having their own legitimate credentials.

Solution

For AMC 3.0, the correction is available as of Support Package 9, Applet Version 171.

Reason and prerequisites

The program code contains a possibility to define and execute user-defined code that changes the behavior of the system. A valid and authenticated user is required. Depending on the code, the user can:

• Inject and run their own code
• Access confidential information
• Modify data, delete data
• Modify the output of the system
• Create new users with higher privileges
• Perform a denial of service attack
