Technical summary

dbcve analysis · high confidence

Unauthenticated HTTP vulnerability in Oracle General Ledger's Account Hierarchy Manager component allows remote attackers to access sensitive data without credentials. The vulnerability affects versions 12.1.1-12.1.3 and 12.2.3-12.2.9 of Oracle E-Business Suite, with high confidentiality impact due to easy network exploitation.

MitigationApply Oracle Critical Patch Update (CPU) for April 2020 or later that addresses CVE-2020-2750; restrict HTTP/HTTPS access to Oracle General Ledger to trusted networks if patching is delayed.

Am I affected?

dbcve checks

Work through these to decide whether this CVE applies to you.

Identify Oracle E-Business Suite installation

Locate the Oracle E-Business Suite installation directory or check for Oracle-specific web applications serving /OA_HTML/ or similar Oracle Application Framework paths

Affected if Oracle E-Business Suite is not installed - this CVE only applies to Oracle EBS
Determine the Oracle E-Business Suite version

Access the Oracle EBS About page (typically at /OA_HTML/AboutOracleEBS.jsp) or check the Oracle applications context file for the release version string

Affected if The installed version falls outside the ranges 12.1.1-12.1.3 or 12.2.3-12.2.9 - only these specific versions are affected
Verify Account Hierarchy Manager is exposed

Check if the Account Hierarchy Manager component is accessible via HTTP/HTTPS by attempting to access paths such as /OA_HTML/zfl/ah/ or monitoring for Oracle General Ledger web endpoints in the application

Affected if The Account Hierarchy Manager component is accessible over HTTP/HTTPS - the vulnerability is an unauthenticated HTTP flaw in this component
Check network exposure

Determine if the Oracle General Ledger application ports (typically 8000-8090 for Oracle HTTP Server) are exposed to untrusted networks by reviewing firewall rules, load balancer configurations, or external access attempts

Affected if The Oracle General Ledger HTTP endpoints are accessible from untrusted networks without authentication filters

A user is affected if their Oracle E-Business Suite is version 12.1.1-12.1.3 or 12.2.3-12.2.9 AND the Account Hierarchy Manager component is accessible over HTTP/HTTPS to untrusted networks.

Generated from the published advisory. Verify against your own configuration.

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.

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.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

CVSS breakdown How the score is builtThe industry scoring standard. It rates how the flaw is reached, what it takes to exploit, and what an attacker gains — the score is derived from those, not the other way round.

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.

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.
