List of CVEs: CVE-2017-7581

This module exploits a SQL Injection vulnerability In TYPO3 NewsController.php in the news module 5.3.2 and earlier. It allows an unauthenticated user to execute arbitrary SQL commands via vectors involving overwriteDemand and OrderByAllowed. The SQL injection can be used to obtain password hashes for application user accounts. This module has been tested on TYPO3 3.16.0 running news extension 5.0.0. This module tries to extract username and password hash of the administrator user. It tries to inject sql and check every letter of a pattern, to see if it belongs to the username or password it tries to alter the ordering of results. If the letter doesn't belong to the word being extracted then all results are inverted (News #2 appears before News #1, so Pattern2 before Pattern1), instead if the letter belongs to the word being extracted then the results are in proper order (News #1 appears before News #2, so Pattern1 before Pattern2)

Module Ranking and Traits

Module Ranking:

  • normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.

Basic Usage

msf > use auxiliary/admin/http/typo3_news_module_sqli
msf auxiliary(typo3_news_module_sqli) > show targets
    ... a list of targets ...
msf auxiliary(typo3_news_module_sqli) > set TARGET target-id
msf auxiliary(typo3_news_module_sqli) > show options
    ... show and set options ...
msf auxiliary(typo3_news_module_sqli) > exploit

Required Options

  • RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'

Knowledge Base

Description

News module extensions v5.3.2 and earlier for TYPO3 contain an SQL injection vulnerability. This module allows an unauthenticated user to exploit the SQL injection vulnerability by generating requests to retrieve the password hash for the admin user of the application. This module has been tested on TYPO3 3.16.0 running news extension 5.0.0.

Vulnerable Application

In vulnerable versions of the news module for TYPO3, a filter for unsetting user specified values does not account for capitalization of the paramter name. This allows a user to inject values to an SQL query.

To exploit the vulnerability, the module generates requests and sets a value for order and OrderByAllowed, which gets passed to the SQL query. The requests are constructed to reorder the display of news articles based on a character matching. This allows a blind SQL injection to be performed to retrieve a username and password hash.

Options

PATTERN1 and PATTERN2

These patterns are used to determine whether the news articles have been reordered. By default, the module will search for headlines and set the first identified headline to PATTERN1 and the second to PATTERN2.

ID

The value for query parameter id of the page that the news extension is running on.

Verification Steps

  • [ ] Install Typo3 VM
  • [ ] Launch the VM and configure it
  • [ ] SSH to the VM
  • [ ] cd /var/www/typo3/ && composer require georgringer/news:5.0.0
  • [ ] Login to the web interface
  • [ ] Enable the news extension
  • [ ] Import vulnerable page
  • [ ] Enable page
  • [ ] Verify if page is visble to unauthenticated user and note the id
  • [ ] ./msfconsole -q -x 'use auxiliary/admin/http/typo3_news_module_sqli; set rhost <rhost>; set id <id>; run'
  • [ ] Username and password hash should have been retrieved
