CVE-2016-7845
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 · uneditedGigaCC OFFICE ver.2.3 and earlier allows remote attackers to upload arbitrary files as a user profile image, which may be exploited for unauthorized file sharing.
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 confidenceGigaCC OFFICE ver.2.3 and earlier contains an arbitrary file upload vulnerability in the user profile image upload functionality. Remote attackers can bypass intended restrictions to upload arbitrary files (not just images), potentially enabling unauthorized file sharing or remote code execution if executable files are placed in web-accessible directories.

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 installed GigaCC OFFICE versionLocate the GigaCC OFFICE installation and check the version information, typically found in the application about page, installation directory metadata, or software inventoryAffected if The installed version is 2.3 or earlier (any version from 2.3 going back to earlier releases)
-
Verify user profile image upload feature is accessibleConfirm that the user profile image upload functionality is enabled and accessible to users in the GigaCC OFFICE web interfaceAffected if The profile image upload feature is available and not disabled in the application settings
-
Inspect upload directory configurationExamine the server configuration to determine where uploaded profile images are stored and whether that directory is web-accessible (served by the web server)Affected if Uploaded files are stored in a directory that the web server can directly serve to users
-
Check server-side file type validationReview the application's file upload handling code or configuration to determine what validation is performed on uploaded files (content-type, file extension, magic bytes)Affected if The application lacks proper server-side validation restricting uploads to only permitted image file types
You are affected if you are running GigaCC OFFICE version 2.3 or earlier with the user profile image upload feature enabled and uploaded files are stored in a web-accessible location without strict server-side file type validation.

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 dataUpgrade to a patched version of GigaCC OFFICE. Implement strict server-side file type validation using magic bytes/content-type checking, restrict upload directories to non-executable locations, and rename uploaded files to prevent direct execution.
