Security firm Onapsis discovered multiple new vulnerabilities affecting the SAP HANA and SAP TREX applications, including critical- and high-risk security flaws. They are thought to impact over 10,000 SAP users, Onapsis reported.
“This set of advisories is unique as most of the vulnerabilities attackers can leverage are undervalued,” said Sebastian Bortnik, head of research for Onapsis. “Meaning the way in which they can be exploited is not always obvious and can go undetected. For example, one of the critical vulnerabilities that can be exploited creates an error message which includes sensitive information about its environment, users or associated data.”
Brute-Force Attacks Against SAP HANA
One concerning vulnerability affecting SAP HANA is a user brute-force attack, which may allow an attacker to directly access business information.
A remote and unauthenticated attacker could exploit this vulnerability and receive high privileges on the HANA system as well as modify arbitrary database information. Tracked as CVE-2016-6144, the vulnerability has a CVSS v3 score of 9.0, according to Onapsis. That makes it a critical one.
There are also lesser high-risk vulnerabilities, including SAP HANA Arbitrary Audit Injection via HTTP Requests and SAP HANA Arbitrary Audit Injection via SQL Protocol. By exploiting this pair of vulnerabilities, an attacker could tamper with the audit logs to hide the evidence of an attack.
All Indexed Information at Risk
Another high-risk vulnerability is a potential remote code execution. If exploited, an unauthenticated attacker could access and modify any information indexed by the SAP system.
The firm also found critical vulnerabilities in SAP TREX, such as the remote command execution. This may allow an untrusted remote user to access and modify any information indexed by the SAP system. Tracked as CVE-2016-6147, the bug has a CVSS v3 score of 10.0.
Full Plate for SAP
SecurityWeek reported that SAP had released its security patches for July 2016. The patches address 24 clickjacking flaws in multiple products. That’s in addition to resolving 21 vulnerabilities and patching 10 security issues since May. That includes a five-year-old issue that was exploited to attack 36 global organizations, the source reported.
Seems SAP has a lot on its plate.
UPDATE, 7/27/16, 2:23 p.m. EDT: Andy Kendzie of SAP media relations contacted Security Intelligence with the following statement:
“SAP Product Security Response Team collaborates frequently with research companies like ERPScan and Onapsis to ensure a responsible disclosure of vulnerabilities. All vulnerabilities disclosed have been fixed, and security patches are available for download on the SAP Service Marketplace. We strongly advise our customers to secure their SAP landscape by applying the available security patches from the SAP Service Marketplace immediately.”
