CVE-2021-2057
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 Retail Customer Management and Segmentation Foundation product of Oracle Retail Applications (component: Internal Operations). The supported version that is affected is 19.0. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Retail Customer Management and Segmentation Foundation. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Retail Customer Management and Segmentation Foundation accessible data as well as unauthorized read access to a subset of Oracle Retail Customer Management and Segmentation Foundation accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Retail Customer Management and Segmentation Foundation. CVSS 3.1 Base Score 6.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/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.
dbcve analysis · moderate confidenceVulnerability in Oracle Retail Customer Management and Segmentation Foundation (version 19.0) in the Internal Operations component. A low-privileged attacker with network access via HTTP can exploit this to achieve unauthorized read, insert, update, or delete access to a subset of accessible data, plus partial denial of service. The nature of the unauthorized data access suggests an injection vulnerability.

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.
-
Verify Oracle Retail Customer Management and Segmentation Foundation is installedLocate the installation directory or check the product inventory on the system. Common locations include Oracle Fusion Middleware home directories or dedicated Oracle Retail installation paths. Check for the presence of the rmsf or equivalent installation folder.Affected if The product is not installed on the system.
-
Confirm the exact installed version is 19.0Check the product version information, typically found in an About dialog, version.txt file, or via the Oracle inventory. Query the Oracle Inventory using opatch lsinventory or check the ORACLE_HOME/rms/version file if present.Affected if The installed version is anything other than exactly 19.0.
-
Determine if Internal Operations component is enabledCheck the component configuration for the Internal Operations module. This may be in the application configuration files, web.xml, or the Oracle Retail system administration console. Look for enabled=true or similar flags related to the Internal Operations component.Affected if The Internal Operations component is present and enabled in the configuration.
-
Verify network accessibility of the HTTP interfaceCheck network listener configuration and firewall rules. Determine if the HTTP port used by the application is exposed to untrusted networks. Review the Oracle WebLogic or Oracle HTTP Server configuration for the application tier.Affected if The HTTP interface is reachable from untrusted network segments.
-
Review access control configuration for low-privileged usersExamine the application role assignments and access control lists. Determine if low-privileged user accounts have permissions that allow access to the Internal Operations component via HTTP endpoints.Affected if Low-privileged users have any network-accessible role to the Internal Operations component.
The environment is affected only if Oracle Retail Customer Management and Segmentation Foundation version 19.0 is installed, the Internal Operations component is enabled, and it is accessible over HTTP to low-privileged users on the network.

From vendor dataApply the Oracle critical patch update (CPU) containing the fix for CVE-2021-2057. Until patched, restrict network access to the Internal Operations component to trusted IPs only and review access controls for low-privileged users.
