CVE-2021-2398
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 Oracle Advanced Outbound Telephony product of Oracle E-Business Suite (component: Region Mapping). Supported versions that are affected are 12.1.1-12.1.3 and 12.2.3-12.2.10. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Advanced Outbound Telephony. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Advanced Outbound Telephony accessible data as well as unauthorized access to critical data or complete access to all Oracle Advanced Outbound Telephony accessible data. CVSS 3.1 Base Score 8.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N).
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 confidenceVulnerability in Oracle Advanced Outbound Telephony's Region Mapping component allows low-privileged attackers with network access via HTTP to modify or access critical data. The flaw appears to be an authorization bypass (likely Insecure Direct Object Reference) where proper access controls on region mapping functions are not enforced for low-privileged users.

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 Advanced Outbound Telephony is installedLocate the Oracle E-Business Suite installation and confirm the Advanced Outbound Telephony module is present. This is typically found in the Oracle Applications manager or through the Oracle E-Business Suite version information pages.Affected if The module is installed and accessible over the network.
-
Check the installed version of Oracle Advanced Outbound TelephonyQuery the Oracle E-Business Suite version information for the Advanced Outbound Telephony component. This is usually accessible through the Oracle Applications menu or by querying the database version tables.Affected if The version falls within 12.1.1 through 12.1.3, or 12.2.3 through 12.2.10.
-
Verify if the Region Mapping component is configured and accessibleCheck if the Region Mapping functionality within Advanced Outbound Telephony is enabled. This typically involves reviewing the module configuration or attempting to access the region mapping screens if you have any level of access.Affected if The Region Mapping component is accessible without elevated privileges.
-
Inspect user access controls on Region Mapping functionsReview the user roles and privileges assigned in Oracle E-Business Suite, specifically focusing on low-privileged users and their ability to access or modify Region Mapping settings. Check if any user with basic privileges can reach these functions via HTTP.Affected if Low-privileged users can access or modify region mapping data without proper authorization checks.
-
Review HTTP access logs for Region Mapping endpoint activityExamine web server or Oracle E-Business Suite access logs for requests to region mapping-related URLs. Look for requests from users who should not have elevated privileges.Affected if Requests to Region Mapping functions are being made by users lacking proper administrative roles.
A user is affected if Oracle Advanced Outephony is installed with a version in the ranges 12.1.1-12.1.3 or 12.2.3-12.2.10, the Region Mapping component is accessible, and low-privileged users can access or modify region mapping data without proper authorization.
