CVE-2020-2643
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedVulnerability in the Enterprise Manager Base Platform product of Oracle Enterprise Manager (component: Job System). Supported versions that are affected are 12.1.0.5, 13.2.0.0 and 13.3.0.0. Easily exploitable vulnerability allows high privileged attacker with network access via HTTP to compromise Enterprise Manager Base Platform. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Enterprise Manager Base Platform accessible data as well as unauthorized update, insert or delete access to some of Enterprise Manager Base Platform accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Enterprise Manager Base Platform. CVSS 3.0 Base Score 6.0 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:L/A:L).
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceOracle Enterprise Manager Base Platform contains a vulnerability in the Job System component that allows a high-privileged attacker with network access via HTTP to compromise the system. Successful exploitation can result in unauthorized access to critical data, unauthorized update/insert/delete operations, and partial denial of service. The vulnerability requires high privileges to exploit but has low attack complexity.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Oracle Enterprise Manager installation and versionLocate the Oracle Enterprise Manager installation directory (commonly $ORACLE_HOME/em or C:\oracle\em) and check for version files such as emctl.pm, version.txt, or use the command 'emctl status -version' if emctl is available. Also check the Oracle inventory for installed Enterprise Manager versions.Affected if The installed version matches exactly 12.1.0.5, 13.2.0.0, or 13.3.0.0
-
Verify the Job System component is accessibleAccess the Enterprise Manager console (typically at https://hostname:7802/em or similar port) and navigate to the Job System functionality. The vulnerability exists in the Job System component, so this component must be accessible for exploitation.Affected if The Enterprise Manager console is accessible and the Job System feature is enabled and reachable
-
Check network exposure of Enterprise Manager consoleDetermine if the Enterprise Manager console (HTTP/HTTPS ports) is exposed to the network. Review firewall rules, load balancer configurations, and the listen address configuration in the emd.properties file (look for 'emd.listen.address' or 'REPOSITORY_URL').Affected if The Enterprise Manager console is reachable over network on HTTP/HTTPS ports from untrusted networks
You are affected if Oracle Enterprise Manager version 12.1.0.5, 13.2.0.0, or 13.3.0.0 is installed and the console with Job System is accessible over the network.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the Oracle Critical Patch Update (CPU) that addresses CVE-2020-2643 for the affected Enterprise Manager versions (12.1.0.5, 13.2.0.0, 13.3.0.0). Oracle CPUs are released quarterly and contain security fixes for multiple vulnerabilities.
