OWASP Vulnerability: Security Misconfiguration

Testing for SQL Injection

---

Using the Burp suite to Test Security Misconfiguration Issues

Firstly ensure that burp suite is configured to your browser

Keep intercept off in the Proxy tab

Now open the page of the web application you want to test.

Now go to burp and select the ‘target’ tab and click on ‘site map’

Locate your application’s name there and choose one of the directories randomly whic the user can access in the application. Here eg. Add attachment.

Click on the link and press spider the branch.

 

Select one of the directories from the ‘site map’ and explore further.

Return to the browser and add the name of the directory to the URL eg.: https://...../addattachment/

Explore all the links, files and directories you are able to find.

Here you will see that the details of the server and other unnecessary information are displayed in the error message which could be a hole for the attacker to attack the system further.

OWASP Vulnerability: Security Misconfiguration Today’s web application is much more complex than they were in the past. These applications developed by web development companies have numerous layers due to which it increases the surface for any potential attack. During the development, deployment, ongoing use, and maintenance process of the web application, it is very important that proper security safeguards are kept by software development companies to reduce any potential ends for exploitation. We need to ensure that the security settings are configured and are checked frequently to protect an organization’s assets. HOW CAN THE VULNERABILITY BE COMPROMISED? As security misconfiguration is a broad category it is one of the common vulnerabilities found in web applications and are hence very easily manipulated too. Web applications are built on multiple layers and hence making mistakes in the configuration in one of the layers is quite common. The vulnerability can be compromised in the following ways: Application server allows stack traces to be returned to the users, specially displays error messages which relieve extra information about the details of the system. Application servers comes with sample apps that are not secured and if these are not removed from the production server that will result in compromising the server. If the directory listing is not disabled on server and if the attacker gains access on the same then the attacker can very easily list directories and execute it. It is also possible to gain access to the actual code which has all the custom code. --> -->Read More: An Important Guide On Angular Directives And Their Types --> --> -->A blockchain comprises blocks that maintain batches of valid transactions. Each block includes the hash of the preceding block in the blockchain, linking the two. The following diagram shows an overview of Blockchain technology and architecture. --> -->Blockchain not only provides a way for the secure transaction but also makes it easy to recover corrupt data as every node inside a blockchain has a copy of data/block. Data loss chances are also minimal as every node has a copy of data. Blockchain is a technology that can be integrated into multiple areas. Some of the areas where Blockchain is useful are payment system and digital currency, cryptocurrency, permission distribution like the distributed voting system, and share power of the voting system. --> How you can discover security misconfigurations First you need to start looking over the system. Are there any default accounts there? If yes then are their passwords changed regularly If it is possible to put better security in the framework, are those possibilities chosen? Does the error message reveal confidential information to the users? Is there any unnecessary features included which can be removed? Read More: Owasp Vulnerability: Missing Function Level Access Control AFFECTED ITEMS AND SEVERITY Affected items: Server Severity: High The impact to the application varies and it depends on the nature of the misconfiguration. DESCRIPTION It is the fifth most critical web application security risk according to OWASO Top ten lists. Security misconfiguration is nothing but incorrectly assembling the safeguards of the web application. Such risks occur when holes are left open in the framework by the developers, DBAs or the administrator. This can occur at any level such as web server, application server, platform, database, custom code or frameworks etc. Such misconfigurations can guide the hacker into the system and this could result in partial or total compromised system. Attackers can easily find these vulnerabilities through default accounts, un-patched flaws, unprotected files, directories, unused web pages and many more. RECOMMENDATIONS TO MITIGATE THE RISKS (AVOID/ REDUCE/ TRANSFER THE RISKS) Security misconfiguration is very easily exploitable but there are number of ways to prevent them. The developers should work with the administrators to make sure that the stack is properly configured. Following are some of the recommendations for the industry experts: Reduce the surface of the vulnerability with a repeatable process Keep the software up to date Develop strong app architecture and encrypt data which has sensitive information. Make sure that the security settings in the framework and libraries are set to secured values. Perform regular audits and run tools to identify the holes in the system Use the same configuration for production, development and staging as inconsistencies opens the gate for many misconfigurations. Automate the system wherever possible to avoid the human errors.
