CVE-2025-9296
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 · uneditedA security vulnerability has been detected in Emlog Pro up to 2.5.18. This affects an unknown function of the file /admin/blogger.php?action=update_avatar. Such manipulation of the argument image leads to unrestricted upload. It is possible to launch the attack remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
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 confidenceEmlog Pro versions up to 2.5.18 contain an unrestricted file upload vulnerability in the /admin/blogger.php?action=update_avatar endpoint. The 'image' parameter accepts arbitrary file types without proper validation, allowing remote attackers to upload malicious files (e.g., web shells) and potentially achieve remote code execution.

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.
-
Determine installed Emlog versionLocate the version file (typically version.php or similar in the Emlog root directory) and read the version number. Check your admin dashboard footer or changelog for version information.Affected if Installed version is 2.5.18 or lower (any version up to and including 2.5.18)
-
Verify /admin/ directory is network accessibleAttempt to access http://your-site/emlog-path/admin/ from an unauthorized network location or check server access logs for attempts to reach /admin/blogger.phpAffected if The /admin/ directory is exposed to unauthenticated or untrusted network access
-
Confirm blogger.php exists with update_avatar actionInspect the file /admin/blogger.php on the server and verify the update_avatar function exists and handles file uploads via the 'image' parameterAffected if The file /admin/blogger.php exists and contains the update_avatar action handler
-
Check for unexpected files in upload directoriesList all files in the media/upload directories (commonly /content/upload/ or similar paths in Emlog). Look for files with non-image extensions such as .php, .phtml, .php5, .htaccess, or .jpg.php.Affected if Non-image files (especially PHP files) are present in upload directories
You are affected if your Emlog installation is version 2.5.18 or lower AND the /admin/ directory is network-accessible to untrusted users.

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 server-side validation for the avatar upload: whitelist allowed file extensions and MIME types (jpg, png, gif), validate image content using getimagesize(), store uploads outside the webroot or rename files to prevent execution, and restrict upload directory to prevent script execution.
