CVE-2026-1021
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 · uneditedPolice Statistics Database System developed by Gotac has an Arbitrary File Upload vulnerability, allowing unauthenticated remote attacker to upload and execute web shell backdoors, thereby enabling arbitrary code execution on the server.
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 confidenceThe Police Statistics Database System by Gotac contains an arbitrary file upload vulnerability that allows unauthenticated remote attackers to upload malicious files, including web shell backdoors, directly to the server. This enables complete remote code execution without any authentication credentials.

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 the installed Gotac Police Statistics Database System versionLocate the application version information in the system documentation, about page, or by inspecting the application headers/banner. Check configuration files or the application metadata for the version number.Affected if The installed version is 1.0.2 or lower.
-
Verify network exposure of the web applicationDetermine if the Gotac Police Statistics Database System web interface is accessible from untrusted networks. Use network scanning or review firewall rules and web server configuration to identify exposed endpoints.Affected if The application's web interface is directly accessible from the internet or untrusted networks without proper network segmentation.
-
Check for unauthenticated file upload endpoint accessibilityIdentify if the file upload functionality can be accessed without authentication. Attempt to access common upload paths or review the application's authentication configuration to verify whether the upload endpoint requires valid credentials.Affected if The file upload functionality is accessible without any authentication credentials.
-
Inspect file upload validation configurationReview the application's configuration files and upload handler code to determine what file type validation, if any, is implemented. Check for allowlisting versus blocklisting approaches and whether content-based validation exists.Affected if The application lacks proper file type validation, content-based validation, or stores uploaded files within the web root with executable permissions.
The system is affected if it runs Gotac Police Statistics Database System version 1.0.2 or lower, has its web interface network-exposed, and allows unauthenticated access to the file upload functionality.

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 dataImplement strict file upload validation including file type allowlisting, content-based validation, authentication requirements for upload endpoints, and store uploaded files outside the web root with no executable permissions.
