CVE-2020-2594
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 Primavera P6 Enterprise Project Portfolio Management product of Oracle Construction and Engineering (component: Project Manager). Supported versions that are affected are 16.2.0.0 - 16.2.19.3, 17.12.0.0 - 17.12.17.0, 18.8.0.0 - 18.8.18.0, 19.12.1.0 - 19.12.3.0 and 20.1.0.0 - 20.2.0.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Primavera P6 Enterprise Project Portfolio Management. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Primavera P6 Enterprise Project Portfolio Management, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Primavera P6 Enterprise Project Portfolio Management accessible data as well as unauthorized read access to a subset of Primavera P6 Enterprise Project Portfolio Management accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Primavera P6 Enterprise Project Portfolio Management. CVSS 3.0 Base Score 6.5 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:C/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 Oracle Primavera P6 installation and versionLocate the Primavera P6 installation directory or access the application About/Admin pages to retrieve the exact version numberAffected if The installed version falls within any of these ranges: 16.2.0.0-16.2.19.3, 17.12.0.0-17.12.17.0, 18.8.0.0-18.8.18.0, 19.12.1.0-19.12.3.0, or 20.1.0.0-20.2.0.0
-
Confirm Project Manager component is in useVerify that the Project Manager module is enabled and accessible within the Primavera P6 deploymentAffected if The Project Manager functionality is active and available to users
-
Verify HTTP network accessibilityCheck if the P6 application is exposed over HTTP/HTTPS network access, as this vulnerability is exploitable remotely via HTTPAffected if The application is reachable over network with HTTP protocol
-
Check for low-privileged user accountsReview user accounts in the P6 administrator console to confirm presence of low-privileged accounts that could potentially exploit this flawAffected if Low-privileged user accounts exist in the system who could potentially exploit the unauthorized data access vector
The environment is affected if Oracle Primavera P6 EPPM is installed with a version matching the affected ranges and the Project Manager component is accessible to low-privileged users over the network.
