CVE-2022-21516
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: Enterprise Manager Install). Supported versions that are affected are 13.4.0.0 and 13.5.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Enterprise Manager Base Platform. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Enterprise Manager Base Platform accessible data as well as unauthorized read access to a subset 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 3.1 Base Score 7.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/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.

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 if Oracle Enterprise Manager Base Platform is installedCheck for the presence of Oracle Enterprise Manager installation directories or look for the 'emctl' command-line utility typically located in $ORACLE_HOME/bin. On Windows, check Program Files for Oracle folders or look for Enterprise Manager services in Windows Services.Affected if Oracle Enterprise Manager Base Platform is found on the system
-
Determine the installed version of Enterprise ManagerRun 'emctl status -version' or 'emctl getversion' from the Oracle Home bin directory. Alternatively, check the Oracle inventory file (inventory.xml) or the EMgcDB directory for version files.Affected if The installed version is exactly 13.4.0.0 or exactly 13.5.0.0
-
Verify the Enterprise Manager Install component is exposedCheck if the Enterprise Manager console HTTP/HTTPS ports (typically 7801-7803 or 5500) are listening and accessible from the network. Use 'netstat -an | grep -E "7801|7802|7803|5500"' or equivalent to identify listening ports.Affected if The Enterprise Manager console ports are exposed to untrusted network access
-
Confirm the vulnerability is network-exploitableReview firewall rules and network ACLs to determine if the Enterprise Manager HTTP endpoints (usually /em/console) are accessible without authentication from outside trusted networks.Affected if The console is reachable via HTTP from untrusted networks without authentication
A user is affected if Oracle Enterprise Manager Base Platform version 13.4.0.0 or 13.5.0.0 is installed and its HTTP console is network-accessible without authentication.

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 that addresses CVE-2022-21516, or upgrade to a patched version of Enterprise Manager Base Platform beyond 13.5.0.0. Restrict network exposure of the Enterprise Manager console to trusted users only as an interim control.
