Several OCX and DLL libraries from 3rd party software (glg.ocx, officeviewermme.ocx, pdfxctrl.dll, vsflex8n.ocx and ChartFX.ClientServer.Core.dll) are vulnerable to buffer overflow and denial of service (IE). Also the application is vulnerable to insecure library loading with every file extension thru ssgp.dll and dwmapi.dll.

When a large buffer is sent to the sub_path item of the StoreInRegistry function, and the sub_key item of the InitFromRegistry function, in pdfxctrl.dll module, we get a SEH overwrite. An attacker can gain access to the system of the affected node and execute arbitrary code.

Discovered on 25.01.2012 included in Mindjet MindManager 2012 for Windows version 10.0.493.

Input passed via the parameters ‘filter’ in ‘widget.dokumenti_lista.php’ and ‘fin_nalog_id’ in ‘nalozi_naslov.php’ script are not properly sanitised before being returned to the user or used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code. The param ‘config’ in ‘nalozi_naslov.php’ and ‘widget.dokumenti_lista.php’ is vulnerable to a XSS issue where the attacker can execute arbitrary HTML and script code in a user’s browser session in context of an affected site.

Infoproject Biznis Heroj (login.php) Authentication Bypass Vulnerability

The vulnerability is caused due to an error in the logon authentication script (login.php) and can be exploited to bypass the login procedure by defining the ‘username’ and ‘password’ POST parameters with an SQL Injection attack, gaining admin privileges.

The issue is triggered when adding 514 bytes of string to the sop:// protocol (GET), causing the app to open the link (channel) and crashing. The application will crash even with ‘sop://[anything]‘ because it fails to properly sanitize and handle the uri segment, but with exactly 514 bytes the stack gets overflowed, poping out the Buffer Overrun error box. Unsuccessful atempts causes denial of service scenario. You can also edit the ‘<address>’ element in the favorites.xml file as the attack vector.

SopCast is also vulnerable to an elevation of privileges vulnerability which can be used by a simple user that can change the executable file with a binary of choice. The vulnerability exist due to the improper permissions, with the ‘F’ flag (full control) for the ‘Everyone’ group, for the ‘Diagnose.exe’ binary file which is bundled with the SopCast installation package.

(CRLF Injection/HTTP Response Splitting) Input passed to the POST parameter ‘editorChoice’ in ‘admin_blocks.php’ and ‘admin_pages.php’ and the POST parameter ‘theme’ in ‘admin_css.php’, ‘admin_js.php’ and ‘admin_templates.php’ is not properly sanitised before being returned to the user. This can be exploited to insert arbitrary HTTP headers, which are included in a response sent to the user.

(LFI/DT) Input passed via the ‘fileName’ parameter thru the simplexml_load_file() function is not properly verified in ‘/admin/admin_blocks.php’ and ‘/admin/admin_pages.php’ (post-auth) before being used to load files. This can be exploited to disclose the contents of arbitrary files via directory traversal attacks.
