Oracle April 2022 Critical Patch Update Addresses 221 CVEs

Oracle addresses 221 CVEs in its second quarterly update of 2022 with 520 patches, including 27 critical updates.

Background

On April 19, Oracle released its Critical Patch Update (CPU) for April 2022, the second quarterly update of the year. This CPU contains fixes for 221 CVEs in 520 security updates across 31 Oracle product families. Out of the 520 security updates published this quarter, 14.8% of patches were assigned critical severity. Medium severity patches accounted for the bulk of the release at 55.2%, followed by high severity patches at 27.1%.

This quarter’s update includes 77 critical patches across 27 CVEs.

Severity Issues Patched CVEs
Critical 77 27
High 141 69
Medium 287 114
Low 15 11
Total 520 221

Analysis

This quarter, the Oracle Communications product family contained the highest number of patches at 149, accounting for 28.6% of the total patches, followed by Oracle Fusion Middleware at 54 patches, which accounted for 10.4% of the total patches.

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.”

Oracle addresses “psychic signatures” vulnerability in Java

Additionally, Oracle addressed CVE-2022-21449, a cryptographic signature vulnerability in Java 15, 16, 17 and 18. It has been referred to as a “psychic signatures” vulnerability by Neil Madden, security architect at Forgerock, who published a detailed blog post about the flaw. While Oracle assigned a CVSSv3 score of 7.5 to the vulnerability, Madden says that Forgerock assigned a CVSSv3 score of 10.0.

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:
