CVE-2020-2781: Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: JSSE).

Vulnerability in the Java SE, Java SE Embedded product of Oracle Java SE (component: JSSE). Supported versions that are affected are Java SE: 7u251, 8u241, 11.0.6 and 14; Java SE Embedded: 8u241. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTPS to compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded. Note: Applies to client and server deployment of Java. This vulnerability can be exploited through sandboxed Java Web Start applications and sandboxed Java applets. It can also be exploited by supplying data to APIs in the specified Component without using sandboxed Java Web Start applications or sandboxed Java applets, such as through a web service. CVSS 3.0 Base Score 5.3 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).

Security readout for executives and security teams

CVE-2020-2781 is a Java JSSE flaw that can let an unauthenticated network attacker trigger partial service disruption over HTTPS. The known impact is availability only, not data theft or code execution. It affects specific Oracle Java SE and Java SE Embedded versions, including server and client deployments. Exposure is most likely where affected Java runtimes support HTTPS services or embedded Java components. Named affected versions are Java SE 7u251, 8u241, 11.0.6, 14, and Java SE Embedded 8u241. Downstream OpenJDK and vendor-packaged Java deployments are also relevant per Linux vendor advisories. Treat this as a routine but time-sensitive availability risk. It is not described as data compromise or remote code execution, but exposed Java HTTPS services could be disrupted. Patch affected Java runtimes through normal security update channels and focus first on externally reachable services. Mitigation focus: Apply Oracle April 2020 CPU or later supported Java security updates.; Update OpenJDK packages according to Debian, Ubuntu, Fedora, openSUSE, or Gentoo advisories.; Check appliances and bundled Java runtimes against vendor advisories such as NetApp..
