Released Proof of Concept Exploits Could Compromise SAP NetWeaver Systems

Released Proof of Concept Exploits Could Compromise SAP NetWeaver Systems

An update to the cybersecurity alert regarding SAP products was issued Thursday, July 16, 2020. Proof of Concept (PoC) exploits released to Github could compromise vulnerable SAP NetWeaver systems. This could potentially lead to a breach.

What It Is:
Multiple vulnerabilities have been discovered in SAP products, the most severe of which could allow an unauthenticated, remote attacker to execute code on the affected systems. SAP is a company that creates software to manage business operations and customer relations.

Successful exploitation of the most severe of these vulnerabilities could allow an unauthenticated, remote attacker to execute code on the affected systems. Depending on the privileges associated with the application, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Applications configured to have fewer restrictions on the system could be less impacted than those who operate with elevated privileges.

• Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
• Remind users not to visit untrusted websites or follow links provided by unknown or untrusted sources.
• Inform and educate users regarding the threats posed by hypertext links contained in emails or attachments especially from untrusted sources.
• Apply the Principle of Least Privilege to all systems and services.

Negative Consequences of Lost or Stolen Data:
The loss or theft of proprietary data can have severe impacts, particularly if the compromise becomes public and sensitive information is exposed. Possible impacts include:

• Temporary or permanent loss of sensitive or proprietary information.
• Disruption to regular operations.
• Financial losses incurred to restore systems and files.
• Potential harm to an organization’s reputation.
