CVE-2016-9484 — Jqueryform Php Formmail Generator security vulnerability

High CVSS 7.5

The generated PHP form code does not properly validate user input folder directories, allowing a remote unauthenticated attacker to perform a path traversal and access arbitrary files on the server. The PHP FormMail Generator website does not use version numbers and is updated continuously. Any PHP form code generated by this website prior to 2016-12-06 may be vulnerable.

Path traversal, unsafe upload, and file handling

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
  • Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
  • Review canonicalization and containment checks across supported operating systems and storage backends.

Remediate safely

  • Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
  • Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
  • Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
