XSStrike is a Cross Site Scripting detection suite equipped with four hand written parsers, an intelligent payload generator, a powerful fuzzing engine and an incredibly fast crawler.
Instead of injecting payloads and checking it works like all the other tools do, XSStrike analyses the response with multiple parsers and then crafts payloads that are guaranteed to work by context analysis integrated with a fuzzing engine.
Here are some examples of the payloads generated by XSStrike:
```
}]};(confirm)()//\
<A%0aONMouseOvER%0d=%0d[8].find(confirm)>z
</tiTlE/><a%0donpOintErentER%0d=%0d(prompt)``>z
</SCRiPT/><DETAILs/+/onpoINTERenTEr%0a=%0aa=prompt,a()//
```
Apart from that, XSStrike has crawling, fuzzing, parameter discovery, WAF detection capabilities as well. It also scans for DOM XSS vulnerabilities.
### Main Features
- Reflected and DOM XSS scanning
- Multi-threaded crawling
- Context analysis
- Configurable core
- WAF detection & evasion
- Outdated JS lib scanning
- Intelligent payload generator
- Handmade HTML & JavaScript parser
- Powerful fuzzing engine
- Blind XSS support
- Highly researched work-flow
- Complete HTTP support
- Bruteforce payloads from a file
- Powered by [Photon](https://github.com/s0md3v/Photon), [Zetanize](https://github.com/s0md3v/zetanize) and [Arjun](https://github.com/s0md3v/Arjun)

Generate README Eval
The generate-readme-eval is a dataset (train split) and benchmark (test split) to evaluate the effectiveness of LLMs
when summarizing entire GitHub repos in form of a README.md file. The datset is curated from top 400 real Python repositories
from GitHub with at least 1000 stars and 100 forks. The script used to generate the dataset can be found here.
For the dataset we restrict ourselves to GH repositories that are less than 100k tokens in size to allow us to put the entire repo
in the context of LLM in a single call. The train split of the dataset can be used to fine-tune your own model, the results
reported here are for the test split.
To evaluate a LLM on the benchmark we can use the evaluation script given here. During evaluation we prompt
the LLM to generate a structured README.md file using the entire contents of the repository (repo_content). We evaluate the output
response from LLM by comparing it with the actual README file of that repository across several different metrics.
In addition to the traditional NLP metircs like BLEU, ROUGE scores and cosine similarity, we also compute custom metrics that capture structural similarity, code consistency (from code to README), readability (FRES) and information retrieval. The final score is generated between by taking a weighted average of the metrics. The weights used for the final score are shown below.
weights = {
'bleu': 0.1,
'rouge-1': 0.033,
'rouge-2': 0.033,
'rouge-l': 0.034,
'cosine_similarity': 0.1,
'structural_similarity': 0.1,
'information_retrieval': 0.2,
'code_consistency': 0.2,
'readability': 0.2
}
At the end of evaluation the script will print the metrics and store the entire run in a log file. If you want to add your model to the leaderboard please create a PR with the log file of the run and details about the model.
If we use the existing README.md files in the repositories as the golden output, we would get a score of 56.79 on this benchmark.
We can validate it by running the evaluation script with --oracle flag.
The oracle run log is available here.
Leaderboard
The current SOTA model on this benchmark in zero shot setting is Gemini-1.5-Flash-Exp-0827. It scores the highest across a number of different metrics.

Few-Shot
This benchmark is interesting because it is not that easy to few-shot your way to improve performance. There are couple of reasons for that:
The average context length required for each item can be up to 100k tokens which makes it out of the reach of most models except Google Gemini which has a context legnth of up to 2 Million tokens.
There is a trade-off in accuracy inherit in the benchmark as adding more examples makes some of the metrics like
information_retrievalandreadabilityworse. At larger contexts models do not have perfect recall and may miss important information.
Our experiments with few-shot prompts confirm this, the maximum overall score is at 1-shot and adding more examples doesn't help after that.
