DescriptionCVE.org

A vulnerability, which was classified as critical, has been found in code-projects Document Management System 1.0. This issue affects some unknown processing of the file /insert.php. The manipulation of the argument uploaded_file leads to unrestricted upload. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.

AnalysisAI

Unrestricted file upload in code-projects Document Management System 1.0 via the /insert.php endpoint allows authenticated remote attackers to upload arbitrary files by manipulating the uploaded_file parameter, potentially enabling remote code execution or data exfiltration. Publicly available exploit code exists, though EPSS score of 0.06% suggests limited real-world exploitation likelihood due to low attack impact and authenticated access requirement.

Technical ContextAI

The vulnerability resides in the /insert.php file of Document Management System 1.0, which handles file uploads. The uploaded_file parameter lacks proper validation or restrictions on file types, sizes, or naming conventions, permitting attackers to bypass intended upload controls. CWE-284 (Improper Access Control) indicates the root cause is inadequate authorization checks or missing file type validation. The PHP-based application processes user-supplied file input without sanitization or server-side enforcement of allowed file extensions or MIME types.

RemediationAI

Apply a patched version from the vendor if available via https://code-projects.org/. If no vendor patch is released, immediately implement server-side file type validation by maintaining a whitelist of allowed file extensions (e.g., .pdf, .docx, .txt) and verifying MIME types server-side rather than relying on user-supplied headers. Rename uploaded files to remove executable extensions and store them outside the web root to prevent direct access. Restrict write permissions on the upload directory to prevent PHP/CGI execution by configuring the web server (Apache: php_flag engine off; nginx: deny .php execution in upload path). Additionally, implement rate limiting on /insert.php to mitigate automated exploitation, and audit existing uploads for suspicious files. If unavoidable, restrict access to /insert.php to specific IP ranges or require additional authentication factors.
