Oracle Security Vulnerability Scoring Metric Change (CVSS)

No, Oracle security vulnerabilities didn’t just get a whole lot worse this quarter.  Instead, Oracle updated the scoring metric used in the Critical Patch Updates (CPU) from CVSS v2 to CVSS v3.0 for the April 2016 CPU.  The Common Vulnerability Score System (CVSS) is a generally accepted method for scoring and rating security vulnerabilities.  CVSS is used by Oracle, Microsoft, Cisco, and other major software vendors.

As we have discussed previously (more...)

Oracle Critical Patch Update January 2016 E-Business Suite Analysis

To start, the January 2016 Critical Patch Update (CPU) for Oracle E-Business Suite (EBS) is significant and high-risk

First, this CPU with 78 EBS security fixes has 10x the number of EBS security fixes than an average CPU.  For the previous 44 CPUs released since 2005, an average of 7.5 security bugs are fixed per quarter for EBS.  Second, there are a significant number of SQL injection and other high risk (more...)

Oracle Database Critical Patch Update (CPU) Planning for 2016

With the start of the new year, it is now time to think about Oracle Critical Patch Updates for 2016.  Oracle releases security patches in the form of Critical Patch Updates (CPU) each quarter (January, April, July, and October).  These patches include important fixes for security vulnerabilities in the Oracle Database.  The CPUs are only available for certain versions of the Oracle Database, therefore, advanced planning is required to ensure supported versions (more...)

DOAG 2015: Best of Oracle Security 2015

Yesterday I gave my yearly presentation “Best of Oracle Security 2015” at the DOAG 2015 conference in Nürnberg. In this presentation I showed different Oracle exploits I found/modified released in 2015 in various sources.

One of the most interesting Oracle bugs in 2015 was CVE-2014-6577 (found by Trustwave, affecting 11.2.0.3, 11.2.0.4, 12.1.0.1, 12.1.02, fixed in April 2015 CPU). This bug can be used as helper (more...)

DAM tools, IBM Guardium, Oracle E-Business Suite, PeopleSoft and SAP

A question we have answered a few times in the last few months is whether or not, and if so, how easy do Database Activity Monitoring (DAM) tools such as IBM Guardium support ERP platforms such as the Oracle E-Business Suite, PeopleSoft and SAP. The answer is yes; DAM tools can support ERP systems. For example, IBM Guardium has out-of-the-box policies for both the E-Business Suite and SAP – see figures one and two below.

Fine Grained Auditing (FGA) and Protecting Oracle E-Business PII Data for Executives

With the recent news about yet another database breach of Personally Identifiable Information (PII), Integrigy had a discussion with a client about how to better protect the PII data of their executives.

The following Fine-Grained-Auditing (FGA) policy started the discussion. The policy below will conditionally log direct connections to the Oracle E-Business Suite database when the PII data of corporate executives is accessed. For example, it will ignore E-Business Suite end-user connections to the database, (more...)

July Security Alert

Hi Oracle Security Folks, The July Oracle Security Alert is out. My part is smaller than last quarter as just an In-Depth Credit, but Mr David Litchfield makes a triumphal return with some excellent new research. http://www.oracle.com/technetwork/topics/security/cpujul2014-1972956.html There is a CVSS 9 and a remote unauthenticated issue in this patch so worth installing this one.

Hi Oracle Security Folks, Thanks to Oracle for fixing a batch of research I sent over in August 2013 regarding ADVISOR, DIRECTORIES, GAOP(GRANT ANY OBJECT PRIVILEGE) and also a critical privilege escalation which gains 8.5 in the CPU which I am not going to publish here as I want to give folks time to patch.

The Art of Exploiting Injection Flaws

Sid is doing his popular course, The Art of Exploiting Injection Flaws, at this year’s Black Hat. You can find more details here. Definitely highly recommended.

INDEX to SYSDBA without SELECT

Hello Oracle Security Readers, If we combine the following factors together then we can identify an escalation route from Index on SYSTEM to SYSDBA which does not require SELECT privileges on the indexed table: 1. SYSTEM passes it’s DBA role through it’s procedures. 2. Oracle indexes allow execution from read via functions i.e. INDEX can [...]

Oradebug allows to run OS commands and to enable/disable Oracle SYSDBA (more...)

New interesting feature of Oracle 12c

This looks like an interesting feature of Oracle 12c. I’m still not sure about the security implications but it does say interesting things about pure network monitoring security tools. Now, more than ever, what you see on the network can be something completely different than what runs on the database. So, you can see a […]
