Gonflus

A comprehensive payload generator for security testing of file uploads, activated with the --burp-oob option.
It produces payloads for various vulnerabilities like SSRF, XXE, RCE, and XSS across common file formats.
With --burp-oob, the payload depth is enhanced with --polyglot, which adds complexity through additional file extensions.
The --webshell option introduces three types of payloads (id, cmd, and burp):
id executes whoami, cmd includes a get variable command, and burp triggers an out-of-band (OOB) request.
The --prompt-ai option generates files with metadata, comments, and body content containing indirect prompt injections,
which attempt to manipulate AI into executing unintended actions or exfiltrate data using a Burp Collaborator.

For a structured overview of known rendering vulnerabilities, CVEs, PoCs, and the exact payloads generated by this tool for each supported format, refer to cve_known_rendering.md at the root of the repository.

Options:

--burp-oob: Burp Collaborator host used for all payloads that require an out-of-band (OOB) endpoint (required for payload types: oob, xxe, ssrf, rce, deserialization, ntlm, or when using all unless you use only --prompt-ai or -d)
--payloads: Specify the payload type(s) to generate (can specify multiple types separated by commas). Default: all
- xxe: XML External Entity injection payloads
- ssrf: Server-Side Request Forgery payloads
- rce: Remote Code Execution payloads
- oob: Out-of-band payloads (automatically includes xxe, ssrf, rce, deserialization, ntlm)
- xss: Cross-Site Scripting payloads (includes files with XSS payloads in filenames)
- ssti: Server-Side Template Injection payloads (includes files with SSTI payloads in filenames)
- deserialization: Deserialization vulnerability payloads
- lfi: Local File Inclusion payloads
- path_traversal: Path traversal payloads
- info: Information disclosure payloads
- info_leak: Information leakage payloads
- dos: Denial of Service payloads
- ntlm: NTLM hash leakage payloads
- all: Generates all payload types (default)
- Examples: --payloads xss, --payloads xxe,ssrf, --payloads oob, --payloads ssti,xss
-e, --extension: Specify the extension(s) to generate (can specify multiple extensions separated by commas):
- pdf, docx, xlsx, pptx: Office Documents
- svg, xml, html: Web Formats
- png, jpg, jpeg, gif: Images
- webm, mp4: Video Formats
- md, markdown: Markdown Files
- zip, jar, epub: Archives
- txt, csv, rtf: Text Files
- odt, ods, odp: OpenDocument
- all: Generates all payloads (default)
- Examples: -e pdf, -e pdf,jpg, -e xml,svg,html
-d, --delete: Deletes all generated folders before creating new payloads (can be used alone)
--polyglot: Generates polyglot payloads with other formats content but the target extension (e.g., SVG content with .xml extension, HTML content with .png extension, PDF+ZIP polyglot). Structure: <extension>/polyglot/<source_format>/<vulnerability>/<payload_file>
--webshell: Generates webshell payloads embedded in legitimate files of the target extension. For each extension, creates webshells for multiple backends (PHP, JSP, ASP, ASPX, Python, Node.js, Ruby, Perl, ColdFusion, etc.) with 3 payload types: id (executes id command), cmd (webshell with cmd parameter), and burp (sends a request to Burp Collaborator). Structure: <extension>/webshell/<backend>/webshell1_<type>.<ext>
--prompt-ai: For each selected extension, generates an ai/ directory containing several files (ai_description.<ext>, ai_author.<ext>, ai_metadata.<ext>, ai_body.<ext>, ai_comment.<ext>) with the prompt injected into metadata fields, document body and comments where the format allows it

Note on payload types:

When using --payloads xss or --payloads ssti, the tool generates legitimate files with XSS/SSTI payloads embedded in the filenames (e.g., <script>alert(1)</script>.pdf, {{7*7}}.png). These files are valid for their extension but have malicious payloads in their names to test filename-based injection vulnerabilities.
The oob payload type automatically expands to include xxe, ssrf, rce, deserialization, and ntlm as these all require out-of-band detection.
Payload types oob, xxe, ssrf, rce, deserialization, and ntlm require the --burp-oob option to be specified.

  └── master.xml

Each payload is named with the technique number and a synthetic name of the technique used.

Master Payloads

For each extension, a "master" payload is generated that combines all vulnerabilities of the extension into a single file. The idea is to first try uploading this master, test as much as possible, and then if no feedback, upload the payloads one by one.

Master payloads are available at the root of each extension directory:

pdf/master.pdf - Contains all techniques SSRF, NTLM, LFI, XXE
pdf/master2_rce.pdf - Contains only RCE techniques (Ghostscript/PostScript) as they may break the main master
docx/master.docx - Contains all techniques SSRF, LFI, XXE
xlsx/master.xlsx - Contains all techniques SSRF, LFI, XXE
svg/master.svg - Contains all techniques SSRF (8 techniques), LFI, XXE, XSS (7 techniques)
png/master.png - Contains SSRF/XXE techniques
png/master2_rce.png - Contains only RCE techniques (ImageMagick)
jpg/master.jpg - Contains SSRF/XXE techniques
gif/master.gif - Contains SSRF/XXE techniques
zip/master.zip - Contains XXE, Path Traversal, RCE techniques
jar/master.jar - Contains XXE, Path Traversal, RCE techniques
epub/master.epub - Contains XXE, Path Traversal techniques
txt/master.txt - Contains XSS, SSRF, Path Traversal, RCE techniques
csv/master.csv - Contains XSS, SSRF, Path Traversal, RCE techniques
rtf/master.rtf - Contains SSRF, XSS, Path Traversal, RCE techniques
odt/master.odt - Contains XXE techniques
ods/master.ods - Contains XXE techniques
odp/master.odp - Contains XXE techniques
xml/master.xml - Contains XXE, XSS, Path Traversal techniques
html/master.html - Contains XSS, SSRF, RCE techniques
pptx/master.pptx - Contains SSRF, XXE techniques
webm/master.webm - Contains OOB, Heap Overflow, UAF, Integer Overflow, RCE, DoS, Info Leak techniques
mp4/master.mp4 - Contains OOB, Heap Overflow, UAF, Integer Overflow, RCE, DoS, Info Leak, SSRF, XSS techniques
md/master.md - Contains RCE (XSS chain, OOB, internal), SSRF, XSS, Info Leak, DoS, OOB techniques

OOB Endpoints Table

For the complete OOB endpoints table and their mapping to vulnerabilities, see OOB Endpoints Table.

This table allows you to quickly identify which payload triggered a request in your Burp Collaborator by searching for the received OOB endpoint.

Polyglot Payloads

The detailed documentation of all polyglot payload families (PDF, Office, images, archives, etc.) has been moved to a dedicated file to keep this README.md lighter.

For the complete tables and explanations, see polyglot_payloads.md.

Webshell Structure Example:

pdf/
  ├── ssrf/
  │   └── ssrf1_xobject_image.pdf
  ├── webshell/
  │   ├── php/
  │   │   ├── webshell1_id.pdf        (PHP webshell executing 'id', embedded in PDF)
  │   │   ├── webshell1_cmd.pdf       (PHP webshell with cmd parameter, embedded in PDF)
  │   │   └── webshell1_burp.pdf     (PHP webshell sending request to Burp, embedded in PDF)
  │   ├── jsp/
  │   │   ├── webshell1_id.pdf        (JSP webshell executing 'id', embedded in PDF)
  │   │   ├── webshell1_cmd.pdf       (JSP webshell with cmd parameter, embedded in PDF)
  │   │   └── webshell1_burp.pdf      (JSP webshell sending request to Burp, embedded in PDF)
  │   └── ... (other backends: asp, aspx, python, nodejs, ruby, perl, coldfusion)
  └── master.pdf

Note: Webshell payloads are embedded in legitimate files of the target extension. For example:

PDF webshells are valid PDF files with webshell code embedded in annotations, JavaScript, or metadata
DOCX webshells are valid DOCX files with webshell code embedded in XML comments or document content
HTML/SVG webshells are valid HTML/SVG files with webshell code embedded in comments or script tags
Image webshells (PNG/JPG) are valid image files with webshell code appended after image headers

This approach helps bypass upload filters by using legitimate file formats that contain the webshell code.

Important: When you see a polyglot file like ssrf1_document_rels_docx.pdf, it means:

The file has a .pdf extension (target extension)
It contains DOCX content (source format)
It uses the same endpoint as ssrf1_document_rels.docx which is /h1 (see DOCX SSRF section)

AI Prompt Payloads

The --prompt-ai option generates, for each selected extension, additional files in an ai/ directory.
These files are legitimate documents (HTML, XML, Markdown, images, PDF, text, etc.) that contain your prompt in:

metadata fields (description, author, custom keys like AI-Prompt)
document body content (where applicable)
comment blocks (HTML/XML comments, EXIF/comment blocks for images, etc.)

The goal is to model indirect prompt injection payloads that target AI systems which automatically read and interpret uploaded content.
When such files are processed by LLM‑powered tools (IDEs, agents, document assistants, etc.), the embedded instructions can try to:

override system and developer instructions
exfiltrate data (for example, sending history, secrets or source code to an attacker‑controlled endpoint)
trigger tool usage (HTTP requests, command execution, file reads, etc.)

For real‑world research and examples of indirect prompt injection against AI tools, see the articles on Embrace The Red, for example the 2025 AI agent and IDE attack series (https://embracethered.com/blog/).
These payloads are intended for authorized red teaming and defensive testing of AI integrations only.

Vulnerable Environments

Image Rendering Lab

For hands-on testing of the PNG/JPG/JPEG payloads (including ImageTragick-style RCE), a minimal vulnerable lab is provided under vuln-images/:

vuln-images/php/ – PHP + Apache + ImageMagick (upload + server-side convert on the uploaded file)

The lab runs in a Docker container and exposes a tiny web UI for uploading images.
See vuln-images/README.md for very short build/run instructions.

Quick commands from the repository root:

# PHP + Apache + ImageMagick  (http://localhost:8081)
cd vuln-images && docker build -f php/Dockerfile -t gonflus-php-imagemagick .
docker run --rm -p 8081:80 gonflus-php-imagemagick

Universal Render Lab (All File Types)

For comprehensive testing of all file types with multiple vulnerability classes, a complete vulnerable lab is provided under vuln-render/:

vuln-render/ – PHP + Apache + LibreOffice + ImageMagick + Ghostscript + exiftool + FFmpeg

This lab renders all supported file types server-side with legitimate preview (text extraction, tables, images, video player) and triggers:

RCE via Ghostscript, ImageMagick, ExifTool, FFmpeg, libpng/libjpeg
SSRF via LibreOffice, ImageMagick, embedded URLs
XXE via PHP XML parsers, LibreOffice, exiftool
XSS via HTML/text rendering
Path Traversal via archive extraction
NTLM Leak via UNC paths

Quick commands from the repository root:

cd vuln-render && docker build -t gonflus-render-all .
docker run --rm -p 8080:80 gonflus-render-all
