CVE-2021-2068
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 Outside In Technology product of Oracle Fusion Middleware (component: Outside In Filters). Supported versions that are affected are 8.5.4 and 8.5.5. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Outside In Technology. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Outside In Technology accessible data as well as unauthorized read access to a subset of Oracle Outside In Technology accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Outside In Technology. Note: Outside In Technology is a suite of software development kits (SDKs). The protocol and CVSS score depend on the software that uses the Outside In Technology code. The CVSS score assumes that the software passes data received over a network directly to Outside In Technology code, but if data is not received over a network the CVSS score may be lower. CVSS 3.1 Base Score 8.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/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 · high confidenceVulnerability in Oracle Outside In Technology's Filters component (versions 8.5.4 and 8.5.5). An unauthenticated attacker with network access via HTTP can exploit this to create, delete, or modify critical data, gain unauthorized read access to a subset of data, and cause partial denial of service. The CVSS assumes the software passes network-received data directly to Outside In code.

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.
-
Locate Oracle Outside In Technology installationSearch for Outside In installation directories or check Oracle product inventory on the system. Common locations include Oracle product directories or application-specific bundled installations.Affected if Oracle Outside In Technology is not found on the system, the vulnerability does not apply.
-
Identify the installed version of Outside In Filters componentCheck version information in the installation directory, product documentation, or application metadata. Look for version files or DLL/version properties in the Outside In binaries directory.Affected if The installed version is exactly 8.5.4 or exactly 8.5.5.
-
Determine if the application exposes Outside In to network inputReview application architecture and configuration to determine if the Outside In Filters component processes data received via HTTP/network requests without sanitization. Check if the application passes network-received data directly to the Outside In SDK.Affected if The application passes unsanitized network data directly to Outside In Filters and is accessible via HTTP from the network.
-
Check network exposure of the affected componentReview firewall rules, application bindings, and network listener configurations to determine if the service using Outside In is accessible over the network on HTTP ports.Affected if The service using Outside In Filters is reachable via HTTP from untrusted network sources.
The environment is affected only if Oracle Outside In Technology version 8.5.4 or 8.5.5 is installed AND the application passes unsanitized network-received data directly to the Outside In Filters component accessible via HTTP.

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 Oracle's security patches for Outside In Technology. If possible, sanitize or validate data before passing it to the Outside In SDK to reduce the attack surface, and ensure the SDK is not directly exposed to untrusted network input.
