Oracle this week released its quarterly Critical Patch Update (CPU), which includes a total of 443 new security fixes. More than half of the addressed vulnerabilities are remotely exploitable without authentication.
This is a record-breaking CPU not only in terms of number of patches (the first to include over 400 fixes), but also in regard to the amount of critical flaws addressed: approximately 100 of the patches deal with vulnerabilities with a CVSS score above 9 (roughly 70 patch bugs featuring a CVSS score of 9.8 or higher).
The most severe of these security flaws are two remotely exploitable issues in Oracle’s SD-WAN Aware and SD-WAN Edge solutions, which are tracked as CVE-2020-14701 and CVE-2020-14606, respectively, and which feature a CVSS score of 10.
Oracle’s Communications Applications received the largest number of patches this month, at 60, with 17 of the vulnerabilities rated critical severity. Forty-six of the patched issues can be exploited by remote, unauthenticated attackers, Oracle reveals in its advisory.
Many of the fixed bugs have been lurking in Communications Applications for years, with the oldest of them being identified in 2016 and 2017, but remaining unpatched despite being considered critical risk.
This month, 52 patches were released for vulnerabilities in Fusion Middleware, with 48 of the issues remotely exploitable without authentication. Several of these flaws were reported three years ago.
A significant number of patches were released for Retail Applications (47 fixes, 42 flaws exploitable remotely, without authentication), MySQL (40 patches, 6 remotely exploitable vulnerabilities), Financial Services Applications (38, 26), E-Business Suite (30, 24), Virtualization (25 fixes, no remotely exploitable flaw), Supply Chain (22, 18), and Construction and Engineering (20, 15).
Applications that received fewer than 20 fixes include Database Server (19 patches, 1 issue that is remotely exploitable without authentication), Enterprise Manager (14, 10), Java SE (11, 11), PeopleSoft (11, 9), Systems (7, 1), JD Edwards (6, 6), Insurance Applications (6, 4), Siebel CRM (5, 5), Health Sciences Applications (4, 4), Commerce (4, 3), GraalVM (4, 3), Food and Beverage Applications (4, 0), GoldenGate (3, 1), Berkeley DB (3, 0), Hyperion (3, 0), Hospitality Applications (1, 1), iLearning (1, 1), Utilities Applications (1, 1), Global Lifecycle Management (1, 0), and TimesTen In-Memory Database (1, 0).
In its advisory, Oracle notes that many of the patches address additional vulnerabilities in the affected products, with the total number of fixed security flaws being much larger than the number of patches.
Additionally, the company underlines the importance of applying the available patches in a timely manner, revealing that it continues to receive reports on previously addressed flaws being actively targeted in malicious attacks.
“Oracle continues to periodically receive reports of attempts to maliciously exploit vulnerabilities for which Oracle has already released security patches. In some instances, it has been reported that attackers have been successful because targeted customers had failed to apply available Oracle patches,” the company notes.
