CVE-2020-9248
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 · uneditedHuawei FusionComput 8.0.0 have an improper authorization vulnerability. A module does not verify some input correctly and authorizes files with incorrect access. Attackers can exploit this vulnerability to launch privilege escalation attack. This can compromise normal service.
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 confidenceHuawei FusionComput 8.0.0 contains an improper authorization vulnerability in a file access control module. The vulnerability exists because the module fails to properly validate certain input parameters, resulting in files being authorized with incorrect access permissions. This allows authenticated attackers to perform privilege escalation by accessing files they should not have permission to access.

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 FusionCompute versionAccess the FusionCompute management interface or check the system information panel to identify the installed version. Typically found under 'System Settings' or 'About' in the admin console.Affected if The installed version is exactly 8.0.0
-
Identify file access control module configurationLocate the file access control module configuration files. This is typically found in the security or permissions settings of the FusionCompute admin interface, or in configuration files under the security module directory.Affected if The file access control module is enabled and configured on the system
-
Review file permission configurationsInspect the file access control rules or permission mappings within the module. Check which user roles are mapped to which file access levels in the authorization configuration.Affected if File access permissions are defined and the module is actively enforcing access controls
-
Examine access logs for permission anomaliesReview system and audit logs for any file access events. Look for access attempts to files that should be restricted based on the user's role, particularly files outside the user's assigned scope.Affected if Logs show file access events by users accessing files they should not have permission to access
The environment is affected if FusionCompute version 8.0.0 is running and the file access control module is enabled, allowing unauthorized file access to occur.

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 the vendor patch from Huawei for FusionComput 8.0.0. Until the patch is available, limit access to the affected module to trusted users only and monitor for unauthorized file access attempts.
