CVE-2020-9090
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 · uneditedFusionAccess version 6.5.1 has an improper authorization vulnerability. A command is authorized with incorrect privilege. Attackers with other privilege can execute the command to exploit this vulnerability. This may compromise normal service of the affected product.
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 confidenceFusionAccess 6.5.1 contains an improper authorization vulnerability where a specific command is authorized with incorrect privilege levels. Attackers possessing lower-privileged access can execute this command to escalate privileges and potentially compromise the product's normal service operations.

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.
-
Confirm FusionAccess installationLocate FusionAccess installation directories or check for FusionAccess services running on the system. Common paths may include /opt/FusionAccess or similar installation directories.Affected if FusionAccess software is found on the system
-
Identify FusionAccess versionRun version detection commands or check version files in the FusionAccess installation directory. Look for version information in product documentation, installation logs, or system inventory tools.Affected if The installed version is exactly 6.5.1
-
Compare version to affected rangeVerify the exact version number matches 6.5.1. Only this specific version is affected; other versions in the 6.5.x family may not be vulnerable.Affected if Version equals 6.5.1 exactly (not 6.5.0, 6.5.2, or other 6.x versions)
-
Assess privilege configurationReview user role assignments and privilege levels configured in FusionAccess. Check if lower-privileged accounts exist that could potentially access the improperly authorized command.Affected if Lower-privileged accounts exist with access to system command interfaces
The environment is affected only if FusionAccess version 6.5.1 is installed and lower-privileged users can access the vulnerable command interface.

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 vendor-provided patches or upgrade to a patched version of FusionAccess that addresses the improper authorization flaw; restrict privileged command access until the patch is applied.
