Analyzing Oracle Security – Oracle Critical Patch Update July 2017

Today Oracle has released its quarterly patch update for July 2017. It fixes a record number of 308 vulnerabilities.

The main highlights are as follows:

  • The number of security issues released every quarter keeps growing. Once again, the vendor issued the highest number of its security patches (308) ever.
  • July’s CPU contains 27 vulnerabilities assessed at critical (CVSS base score 9.0-10.0), including one rated the maximum of 10.0.
  • This patch update also contains a record-breaking number of PeopleSoft fixes totaling 30. However, not only the number, but the criticality of issues is alarming. 20 of them can be exploited over the network without user credentials. The vulnerability identified by ERPScan researchers allows executing commands on the PeopleSoft server remotely .

Analysis of Oracle Critical Patch Update July 2017

Below you can find an analysis of the vulnerabilities closed by this Critical Patch Update provided by ERPScan Research and Security Intelligence teams.

The graph above shows that the vendor released yet another record-breaking set of CPUs. It’s especially notable taking into account that the previous update (April’s one) used to be the largest and first-ever reached a 300-issue mark. It safe to say that a constant trend of growing volume of Oracle CPU is here to stay.

We can assume that researchers’ have changed their mindset and focus on business software, which results in a record-breaking number of patches for one or another component. Of course, in the future, it will improve the level of security. However, now it’s is not the matter of finding bugs, but to release a patch (just imagine, 300 patches mean that at least 3 vulnerabilities are identified every day) and then install it in a timely manner, which is a difficult and monotonous task.

Vulnerabilities in Oracle’s business-critical applications

The fact that Oracle has 110,000 applications customers from a wide range of industries, makes it of the utmost importance to apply the released security patches.

This quarter’s CPU contains 82 patches for vulnerabilities affecting a scope of the most crucial business applications from Oracle, namely, Oracle PeopleSoft, E-Business Suite, Siebel CRM, Oracle Financial Services, Oracle Primavera Products Suite. About 53% of them can be exploited remotely without authentication.

Oracle PeopleSoft Security

This Oracle’s Critical Patch Update is characterized by the alarming number of patches for PeopleSoft. This quarter, the vendor released 30 fixes addressing the component (10% of the update). For comparison, last year there were 44 PeopleSoft patches in total.

Speaking about the state of PeopleSoft security, we should take into account not only the number, but the severity of the closed vulnerabilities. The highest CVSS score is 8.3. 20 of these security loopholes can be exploited over the network without requiring user credentials.

To make matters worse, ERPScan research team has recently conducted a custom scan that revealed that more than 1000 PeopleSoft applications were exposed to the Internet, with the majority of them located in the North America.

We should also mention a vulnerability (CVE-2017-10061, CVSS base score 8.3) in the PeopleSoft Enterprise PeopleTools component found by ERPScan researchers. It allows exploiting a directory traversal vulnerability and upload a file, but can be leveraged to execute any command on the server remotely without authentication.

Oracle PeopleSoft combines Supplier Relationship Management, Human Capital Management, Supply Chain Management, and other applications. The software has 6000+ enterprise customers and serves 20 million end users worldwide including more than 800 universities. Over 1000 PeopleSoft systems are available on the Internet putting organizations at risk. According to the latest research from Crowd Research partners, 89% of responders agreed that the number cyber attacks on ERP will significantly grow in the near future. SAP Attacks may cost up to $50m, PeopleSoft is definitely the same weight category.

-commented Alexander Polyakov, CTO at ERPScan.

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 numerous 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 installed in an organization.

Oracle vulnerabilities identified by ERPScan Research team

This quarter, 6 critical vulnerabilities discovered by ERPScan researchers were closed.

The details of the identified issues are provided below:

    • Remotely stopping WebLogic server using T3 protocol (CVSS base score 8.6, CVE-2017-10147). An attacker can use a special T3 request to stop remote server.
    • Directory Traversal vulnerability in Integration Gateway (PSIGW) (CVSS base score 8.3, CVE-2017-10061). The up-to-date Oracle PeopleSoft HCM 9.2 suffers from directory traversal vulnerabilities which can be leveraged to potentially get remote command execution on the server. Some well-known impacts of Directory Traversal vulnerability are as follows: an attacker can read content of arbitrary files on the remote server and expose sensitive data, as well as overwrite, delete, or corrupt arbitrary files on the remote server.
    • File Upload in Integration Gateway (PSIGW) (CVSS base score 8.3, CVE-2017-10061). An attacker can upload arbitrary text files, which can be leveraged to get remote command execution on the server (for example, an attacker can write his own public RSA key in ~/.ssh/authorized_keys file and get valid SSH session).
    • Authentication bypass and directory traversal vulnerability in psft.pt8.cs servlet (CVSS base score 8.3, CVE-2017-10146). An attacker could read content of arbitrary files on the remote server and expose sensitive data.
    • Multiple XSS (POST request ) Vulnerabilities in com.peoplesoft.pt.portlet.service.test.TestServlet (PeopleSoft) (CVSS base score 6.1, CVE-2017-10106). Attacker can use special HTTP request to hijack session data of administrators or users of the web resource.
    • Anonymous log injection using T3 protocol in PeopleSoft (CVSS base score 5.8, CVE-2017-10148). An attacker can use a special T3 request to inject special data to log files.

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.
