SAP Security Notes December 2015 – Review

SAP has released the monthly critical patch update for December 2015. This patch update closes 26 vulnerabilities in SAP products (19 Patch Day Security Notes and 7 Support Package Security notes), 16 of which are high priority. This month, two critical vulnerabilities found by ERPScan researchers Alexander Polyakov, Mathieu Geli and Vahagn Vardanyan were closed.

The largest part of vulnerabilities closed by this update relates to the “other” type according to SAP’s blog post. This is quite typical for business applications such as SAP. Due to their uniqueness and complexity, there are much more uncommon vulnerabilities comparing to traditional software where, as our research Analysis of 3000 SAP Security notes revealed, configuration issues constitute only 2%. Last year we analyzed SAP Security Notes by type, and about 300 vulnerabilities of almost 3000 were defined as configuration issues and about 150 were uncategorized. Configuration and other unusual issues in SAP are 5 times more common than in traditional products, thus, a significant part of cybersecurity measures falls on shoulders of administrators.

Chinese attack on USIS using SAP vulnerability – Detailed review and comments

On 11th of May, a security headline broke the news about the USIS cyber attack (U.S. Investigations Services) potentially conducted by Chinese state-sponsored hackers via a vulnerability in SAP Software. Hackers broke into third-party software in 2013 to open personal records of federal employees and contractors with access to classified intelligence, according to the government’s largest private employee investigation provider [1].

USIS is a federal contractor which conducts background checks for DHS – the largest commercial provider of background investigations to the federal government. It has more than 5,700 employees providing services in all 50 states of the U.S. territories and overseas. As the result of the breach, more than 27,000 personnel seeking security clearances were compromised. Similar hacks also affected servers at the Office of Personnel Management (OPM), which holds information on security clearance investigations. Once hackers have a list of employees who possess government security clearances, they can exploit other aspects of those employees’ lives for further malicious gain.
