Two CVEs receive the highest possible CVSS Score

This month’s CPU release included two CVEs that were given a CVSSv3 score of 10.0, the highest possible severity.

CVE-2022-22947 is a vulnerability impacting the Oracle Communications product family that can be exploited by an unauthenticated attacker with network access via HTTP. This vulnerability would allow a remote attacker to exploit arbitrary code when the Spring Cloud gateway actuator is enabled and unsecured.

CVE-2022-21431 is a vulnerability in the Connection Manager component of the Oracle Communications Billing and Revenue Management product that can be exploited by an unauthenticated attacker with network access via TCP to gain full control of the Billing and Revenue Management service; however, Oracle indicates that exploitation of this vulnerability could “significantly impact additional products.”

Three product families receive only third party patches

While 31 product families received security patches this quarter, Oracle did not include security patches for three product families:

Oracle Global Lifecycle Management
Oracle NoSQL Database
Oracle Secure Backup

While these three product families did not receive security patches, Oracle notes that there are third-party patches included as part of its CPU release:

Third party patches also include fixes for Apache Log4j

Oracle has also addressed multiple additional third party patches in this release, including fixes for vulnerabilities in Apache Log4j, most notably a remote code execution vulnerability dubbed Log4Shell and originally disclosed in December.

A full breakdown of the patches for this quarter can be seen in the following table, which also includes a count of vulnerabilities that can be exploited over a network without authentication.
