CVE-2020-2778

Description

From CVE.org

Vulnerability in the Java SE product of Oracle Java SE (component: JSSE). Supported versions that are affected are Java SE: 11.0.6 and 14. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTPS to compromise Java SE. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Java SE accessible data. 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 3.7 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N).

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)

Confidentiality

Technical Impact: Read Application Data

The confidentiality of sensitive data may be compromised by the use of a broken or risky cryptographic algorithm.

Integrity

Technical Impact: Modify Application Data

The integrity of sensitive data may be compromised by the use of a broken or risky cryptographic algorithm.

Accountability,Non-Repudiation

Technical Impact: Hide Activities

If the cryptographic algorithm is used to ensure the identity of the source of the data (such as digital signatures), then a broken algorithm will compromise this scheme and the source of the data cannot be proven.
