SAP Addresses High Severity Vulnerabilities With July 2017 Patches

SAP today announced that a total of 12 Security Notes were included in its July 2017 Security Patch Day, including four notes that address high severity vulnerabilities.

Of the 12 Security Notes, 2 were updates to previously released Patch Day Security Notes, the German software maker reveals. Cross-Site Scripting and Information Disclosure bugs were the most common types of isses addressed.

Additionally, SAP released 11 Support Package Notes, for a total of 23 Security Notes. Overall, 11 of the Notes were released after June 13, but before July 11. Of the 23 Notes, 5 were updates to previously released Security Notes, ERPScan reveals.

The most severe of the addressed vulnerabilities involved Missing authorization checks in SAP Point of Sale (POS) Retail Xpress Server. With a CVSS score of 8.1, the bug could be exploited to read, write, or delete files stored on SAP POS server; shutdown the Xpress Server application; and monitor all content displayed on a receipt window of a POS.

“An attacker can use a Missing authorization check vulnerability to access a service without any authorization procedure and use service functionality that has restricted access. This can lead to an information disclosure, privilege escalation, and other attacks,” ERPScan explains.

Another High severity bug was a Missing authorization check vulnerability in SAP Host Agent. With a CVSS score of 7.5, the issue “could allow an attacker to remotely restart SAP Host Agent without authentication, through a specific crafted SOAP request,” security firm Onapsis reveals.

The company explains that all SAP Host Agent versions up to 7.21 PL24 are affected, including all Netweaver-based applications and HANA 1 and HANA 2. The issue was resolved in SAP Host Agent version 7.21 PL25. SAP HANA users should upgrade to Revision 122.10 (for SAP HANA1.00 SPS12), Revision 2.02 (for SAP HANA2.0 SPS00), or Revision 12 (for SAP HANA2.0 SPS01).

The remaining High priority security notes include: Improved security for outgoing HTTPS connections in SAP NetWeaver, with a CVSS score of 7.4; and Missing authorization-check in BC-SRV-ALV, with a CVSS score of 6.0. Both are updates to previously released security notes.

Other dangerous vulnerabilities addressed this month in SAP products include a Code injection vulnerability (CVSS Base Score: 6.5) in SAP Governance, Risk and Compliance Access Controls (GRC); Cross-site scripting and Cross-site request forgery (CVSS Base Score: 6.1) in SAP CRM Internet Sales Administration Console; an XML external entity vulnerability (CVSS Base Score: 6.1) in SAP BI Promotion Management Application; and an XML external entity vulnerability (CVSS Base Score: 5.4) in SAP Business Objects Titan.

“This month only 43% of notes require no manual steps besides note installation. Installing these notes is easier than the other ones and patching them has direct impact on information security. This percentage is lower than the average (usually between 60% and 75%) so this means this month’s users should perform more manual steps to have better coverage of patches in their environments,” Onapsis explains.
