Most of the data validation is done by the client and not by the server.
The sensitive data stored by these apps usually include username, passwords, database credentials, license details, cryptographic keys, and configuration details like IP address, port, etc…The attacker can get access to these sensitive details and might compromise the application. An example of a thick client application can be a JAVA or VB.NET, Visual Basic application that communicates with a database.Below is the list of security checks that can be performed on thick clients on top of the business logic checks.
Thick Client ApplicationSecurity AssessmentSanjay KumarInformation Security Specialistsanjay1519841@gmail.comPresented in NULL DELHI meet on 25thMay 2013 2. You will not be spammed.Infosec Skills keeps your security skills fresh year-round with over 400 courses mapped to the National Initiative for Cybersecurity Education’s CyberSeek model.
The application server, in turn, queries a database to fetch/store data.Web applications, also known as Thin Clients, are browser-based applications that run on a web server. As a result both the request as well as response modifications play a key role in testing the thick client for vulnerabilities.Consider a thick client applications that displays the GUI(modules/sub-modules) based on the response parameters received from the server after authentication.For example,when an Admin logs in, the response sent by the application is as follows:When a low privileged user logs in, the response sent by the application is as follows:Exploit: In this case, the attacker or the lower privileged user will intercept the response and modify the User and Account_No parameter to that of the Admin and get access to the administrator module.As we discussed above,the major validations are carried out at the client side, a faulty implementation of authentication process has been observed in various two tier apps and is described below.When a user enters the user name and password in the application, the application sends a SQL query to the database containing the username to retrieve the user credentials.The response received from the database is as follows:It can be observed that only the username is sent to the database, and the database sends the valid password back in the response.
Examples of connection drivers are ODBC (Open Database Connection) and JDBC (Java Database Connection).Thick Clients developed on a two-tier architecture send database queries directly to the database and business logic is executed on the basis of the records/response from the server.These types of thick clients have the following three components:In this architecture, the client application communicates with an application server over an HTTP protocol.

Mallory comes to the rescue in such cases.The ideal setup for Mallory is to have a “LAN” or “Victim” network that Mallory acts as the gateway for. Archives. As the majority of logic resides on the client side, faster performance is observed due to a reduced dependency on the server.As Thick Clients are not dependent on the browser, browser-related vulnerabilities are not applicable to them.However the following key vulnerabilities are associated:As Thick Clients differ from web applications, the testing methodology also varies.
Tags: Final results include detailed analysis report, detected vulnerabilities list, prioritization and actionable recommendations on the risk prevention or mitigation. Traffic can be intercepted in real-time or manipulated with regular expressions and a number of action directives.In this option, the path of the application is provided into the Echo Mirage tool and it launches the selected application. I write about cyber security and free courses.
By setting up proper filters, it can be set to only capture the data related to a particular process.Set the Process Monitor tool to intercept the registry activity as shown below:Analyze the registries accessed by the application to check for sensitive details like keys, encrypted passwords, etc…Set the Process Monitor tool to intercept the file access activity, as shown below:Analyze the files accessed by the application to check for sensitive details like configuration details, log writing, caching files in folders, etc…Listed below are a few sample exploits that a thick client application may face:A thick client tool (licensed version of a tool)after license registration on ‘A’ machine stores the license validation key and expiry date in encrypted format as a value in the registry. Infosec Skills helps you: In this type, the application is installed on the client side, which directly communicates with the database on the server. In Two-Tier architecture, the application interacts directly with the database.This is usually seen in legacy applications and is considered insecure.. An example of a thick client application can be a JAVA or VB.NET, Visual Basic application that communicates with a database.
