Vulnerabilities in Oracle’s business-critical applications
The fact that Oracle has 110,000 applications customers from the wide range of industries, makes it of the utmost importance to apply the released security patches.
This quarter, Oracle CPU contains about 153 patches (64%) for vulnerabilities affecting a scope of the business applications, namely, PeopleSoft, E-Business Suite, Financial Services Applications, Fusion Middleware, Hospitality Applications, Supply Chain Products Suite, Retail Applications, Communications Applications, Health Sciences Applications, Database Server, JD Edwards Products, etc. 99 (almost 65%) of them can be exploited remotely without entering credentials.
Oracle PeopleSoft Security
Oracle PeopleSoft is an application suite of business and industry solutions such as PeopleSoft Human Capital Management, Financial Management, Supplier Relationship Management, Enterprise Services Automation, and Supply Chain Management. As it manages a wide range of business processes and stores key data, a successful attack against PeopleSoft allows an attacker to steal or manipulate different business-critical information, depending on modules that are installed in an organization.
Between this and the previous CPUs, Oracle urgently closed severe issues including a vulnerability dubbed JoltandBleed (CVE 2017-10269). As you remember, this vulnerability allows an attacker to gain full access to all data stored in the following ERP systems:
- Oracle PeopleSoft Campus Solutions
- Oracle PeopleSoft Human Capital Management
- Oracle PeopleSoft Financial Management
- Oracle PeopleSoft Supply Chain Management, etc.
This quarter, the vendor released 15 fixes addressing the component. 8 of these security loopholes can be exploited over the network without requiring user credentials.
The highest CVSS score is 9.8.

In July 2017, Oracle patches grew dramatically and peaked at 30, and then slid slowly but steadily in the next two quarters.
Oracle E-Business Suite Security
Oracle E-Business Suite (EBS) is the main business software developed by Oracle. As it manages a wide range of business processes and stores key data, a successful attack against Oracle EBS allows an attacker to steal and manipulate business-critical information, depending on modules installed in an organization.
This critical patch update contains 7 fixes for Oracle EBS. 4 of these security loopholes can be exploited over the network without requiring user credentials. The highest CVSS score is 9.1.

Since January 2017, the Oracle EBS fixes fell considerably, reaching a low of 11 in April 2017 and ended the last quarter of the passed year at 26. The patch update for January 2018 contains 7 Oracle EBS fixes like in April 2016.
Oracle vulnerabilities identified by ERPScan Research team
This quarter, 1 critical vulnerabilities discovered by ERPScan researchers were closed.
The details are provided below:
- Disclose PIA user and FQDN PeopleSoft server name (PSIGW/PeopleSoftListeningConnector) (CVSS base score 6.5, CVE-2018-2605). With disclosure in PSIGW/PeopleSoftListeningConnector attackers can get PIA user and FQDN PeopleSoft server name.
The most critical Oracle vulnerabilities closed by CPU January 2018
Oracle prepares Risk Matrices and associated documentation describing the conditions that are required to exploit a vulnerability, and the potential impact of a successful attack.

Securing Oracle applications
It is highly recommended that organizations patch all those vulnerabilities to prevent business risks affecting their systems. Companies providing Oracle Security assessment and Oracle Penetration testing services should include these vulnerabilities in their checklists. The tests for the latest vulnerabilities in Oracle PeopleSoft are included in ERPScan Security Monitoring Suite for Oracle PeopleSoft.
