DoS vulnerability in Enqueue service

One of the most critical loopholes fixed this month is a Denial of Service vulnerability in SAP Standalone Enqueue Server found by ERPScan researchers. This issue can be exploited by hackers in order to shut the business processes down, therefore compromising the company (the details are provided below).

After a today’s brief scan, ERPScan’s Research and Threat Intelligence Team has identified around 3000 instances of SAP systems with Enqueue service available online that pose a high risk of cyberattacks. The majority of these services are located in North America.

This is one of the most widespread SAP vulnerability this year so far.

SAP Mobile platform vulnerabilities

Nowadays companies tend to use more business applications and constantly involve mobile devices in their core business processes.

SAP like any other large vendor is also evolving towards greater mobility, therefore provides solutions for mobile users to interact with business applications.

SAP Mobile Platform (or SMP) is a mobile enterprise application platform solution designed to monitor and manage applications installed on mobile phones and access business data.

The “mobilization” opened unintentional doors to all the evil that comes along with integration and security. The purpose of SMP is providing business data to mobile devices with the enterprise cybersecurity.

This month, 4 issues in different components of SAP Mobile infrastructure were patched. Among them are 3 Information Disclosure vulnerabilities in SAP NetWeaver Mobile Client and one possible leakage of sensitive data in SAP Mobile Platform SDK. The vulnerabilities allow gaining access to critical data stored on mobile devices that use SAP NetWeaver mobile client such as passwords, keys and other sensitive information.

SAP users are recommended to implement security patches as they are released.
