# XSLT Server Side Injection (Extensible Stylesheet Languaje Transformations) {{#include ../banners/hacktricks-training.md}} ## Basic Information XSLT ni teknolojia inayotumika kubadilisha hati za XML kuwa katika muundo tofauti. Inakuja katika toleo tatu: 1, 2, na 3, ambapo toleo la 1 ndilo linalotumika zaidi. Mchakato wa kubadilisha unaweza kufanywa ama kwenye seva au ndani ya kivinjari. Mifumo ambayo inatumika mara nyingi ni pamoja na: - **Libxslt** kutoka Gnome, - **Xalan** kutoka Apache, - **Saxon** kutoka Saxonica. Ili kutumia udhaifu unaohusiana na XSLT, ni muhimu kwa xsl tags kuhifadhiwa kwenye upande wa seva, kisha kufikia yaliyomo hayo. Mfano wa udhaifu kama huo umeandikwa katika chanzo kifuatacho: [https://www.gosecure.net/blog/2019/05/02/esi-injection-part-2-abusing-specific-implementations/](https://www.gosecure.net/blog/2019/05/02/esi-injection-part-2-abusing-specific-implementations/). ## Example - Tutorial ```bash sudo apt-get install default-jdk sudo apt-get install libsaxonb-java libsaxon-java ``` ```xml:xml.xml CD Title The artist Da Company 10000 1760 ``` ```xml:xsl.xsl
