In SAP Host Agent (Windows) - versions 7.21, 7.22, an attacker who gains local membership to SAP_LocalAdmin could be able to replace executables with a malicious file that will be started under a privileged account. Note that by default all user members of SAP_LocaAdmin are denied the ability to logon locally by security policy so that this can only occur if the system has already been compromised.

Weakness

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

Affected Software

Name Vendor Start Version End Version
Host_agent Sap 7.21 (including) 7.21 (including)
Host_agent Sap 7.22 (including) 7.22 (including)

Extended Description

Access control involves the use of several protection mechanisms such as:

When any mechanism is not applied or otherwise fails, attackers can compromise the security of the product by gaining privileges, reading sensitive information, executing commands, evading detection, etc. There are two distinct behaviors that can introduce access control weaknesses:

Potential Mitigations

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
