SAP Security Notes March 2011 – Review


SAP released monthly critical patch update for April 2011. This patch updates close 7 public vulnerabilities in SAP products. 4 of those vulnerabilities were founded by ERPScan researchers Alexander Polyakov and Dmitriy Evdokimov.

SAP traditionally sent acknowledgements for the found vulnerabilities to security researchers from ERPScan on their acknowledgement page.

The most critical one is authentication bypass that can be exploited remotely to gain unauthorized access to SAP NetWeaver systems which have CVSS score 9.0 (priority 1 according to SAP metrics). Others are cross-site scripting and information disclosure vulnerabilities in SAP NetWeaver.

It is highly recommended to patch all those issues to prevent business risks.

Solutions for those issues are available in SAP Security Notes: 1503579, 1503856,1475767, 1486679

Advisories for those issues with technical details will be available in 3 month on

Exploits will be available soon in ERPScan Security Scanner – innovative SAP vulnerability assessment solution and ERPScan SaaS.
