A Reflected XSS vulnerability in this sdk #43

Open jgj212 opened 7 years ago

jgj212 commented 7 years ago

Hello: I found a Reflected XSS vulnerability in this sdk.

The vulnerability exists due to insufficient filtration of user-supplied data in “token_secret” HTTP REQUEST parameter that will be passed to “restapi-php-sdk-master\Immocaster\Oauth\example\client.php”. The infected source code is line 7, there is no protection on $_REQUEST['token_secret']; code1

if $_REQUEST['token_secret'] contains evil js code, line 102 will trigger untrusted code to be excuted on the browser side code2

So if a attacker construct a special url as follow and send it to a victim, when the victim click the url, the code which is contained in the url will be executed on the victim's browser side to do some evil. http://your-web-root/restapi-php-sdk-master/Immocaster/Oauth/example/client.php?token_secret="> Githubissues.
