8 Most Common Website Security Vulnerabilities

8 Most Common Website Security Vulnerabilities

The website of your company is the identity of your business on the cyberspace. To ensure that your business is accessible throughout the year, you need to have an effective website. However, just like the bricks and mortar business is prone to physical and natural threats; the website also faces a number of security issues. There are more than hundreds of issues and threats which have the ability to affect the stored data and overall structural website. This article talks about the most popular security threats that your business might be ignoring:


1) Injection Flaws

This issue could arise due to the failure filtering of non-trusted input. Whilst designing or updating the website, when unfiltered data is passed to the SQL server, browser, to the LDAP server or to anywhere else, this issue is bound to arise. The hackers and attackers could inject various commands to the given entities, and eventually, it results in loss of data. It means that all the inputs in a dynamic website need to be filtered which could be a very difficult and long process. This implies that if the website has a thousand entries per day, cross-checking 999 will still leave the scope of vulnerability within the system.

Possible Solution

The basic rule will be to ensure validation of all the inputs and not to completely trust from any user.

2) Broken Authentication

This aspect consists of a number of issues all rolled into a single issue that could be described as broken authentication. Some of the most common authentication related issues could include:

  • The URL of the website could have session ID which could be leaked
  • The unencrypted passwords issues in transit or storage
  • For some hackers, gaining access is easier due to trivial session ID’s
  • Fixing the sessions could be possible
  • Without SSL or proper security, hijacking the sessions could be really easy for the hackers

Possible Solution

The users could be validated for ensuring that spoofing into the protected areas or circumvention the security features is restricted.

3) Cross-Site Scripting:

XSS as it is generally called targets the users by injecting a code which is most generally a client-side script like JavaScript within the web application’s output. The overall concept is simple: to manipulate the scripts at the client’s side to ensure that execution is carried out in the manner desired by the attacker. If your website is attacked, the attacker could use XSS to execute the scripts in the browser which would eventually result in hijacking the sessions, destabilizing the website, defacing the interface, or even redirect the users to other malicious or spam-based websites. The aftermath of the attack has been provided in the given pie chart.


Possible Solution

Any malicious attempt to exploit the vulnerability of the system should be prevented. For example, the websites created by Process Venue are screened and methods are fitted into place for prevention of such acts.

4) Insecure References:

Insecure direct object reference is a condition where a web application exposes or transfers the reference to any internal implementation object. If your website is attacked, the attacker could take use of the reference, and accordingly, if the authorization is not enforced or broken, the attacker would have direct access to the objects which should be rather closed out or secluded from any external parties. Let’s take an example: if the code has a download.php module that reads and provides authorization to the user to download a multiple or single files by taking use of a CGI parameter for specifying the file name (something like download.php?file=something.txt). Due to any reason, the developer could omit the authorization from the code. This means that the attacker now knows that any file from the system could be downloaded with the PHP access.

Possible Solution

The direct references should be exposed to database structures for ensuring that SQL statements and other database processes only allow authorized records to be shown.

5) Security Configuration Issues:

This is particularly based on the maintenance related issues which your website might be facing. When you do not pay enough heed towards website application configuration, the security misconfiguration issues might arise. For various applications, frameworks, application servers, web servers, database servers, and platforms, the secure configuration has to be defined and deployed. Any short measures in this area would result in complete compromise of the system and database of the network.

Possible Solution

By having the maintenance related jobs performed by in-house experts or by outsourcing it to an efficient third-party vendor.

6) Sensitive Data Exposure:

The overall concept of The overall concept of website security is based on crypto and resource protection. Your website should be secured in such a manner that sensitive data should be protected at all the times, even when it is in transit or put on rest. There cannot be any half-measures or exceptions to that. Any information related to credit cards, user passwords could be attacked in transit by the attackers, and eventually, it could result in loss of data due to weak hashing algorithm used by the developers.

Possible Solution

The coding process should be impeccable since the attackers don’t break crypto directly; the database is broken in specifically during transit or at rest.

7) Cross-Site Request Forgery:

It is a malicious exploit of a website where unauthorized commands originate from a user which is trusted by the web application. It is different from XSS where the user’s trust for a particular website was exploited; here, the trust of a site on the browser is exploited by the attackers. There are various examples when websites of large companies like Netflix and ING Direct have been affected by the attackers through CSRF.


Possible Solution

Having proper security checks and security audits in place will help in reducing such incidents.

8) SQL Injections:

It is another common way of attacking the website where the attacker attempts to use the application code to access the content on your website. If this attack is successful, the attacker has direct access to the information stored in the back-end database which could be ultimately used to amend the database. It is one of the most common ways of attacking the websites.

Possible Solution

Encrypting the data and cleaning or validating the inputs could be the best ways of preventing such attack.
