53 53  Once Java code execution is possible, it is trivial to execute arbitrary OS commands using the java.lang.Runtime class. The attached PoC will not read the output of the executed command (because loops are hard in XSLT). But this is not a problem if a reverse-shell have already been started, isn't it ;-)

62 +The "write" extension element allows to create files on the engine side. The content written to the file must be valid UTF-8 (so plain ASCII works too). Existing files can be overwritten.
