Web Security Issues that must be avoided at all Cost

Web Security Issues – Technology is always changing. Some website security experts just learn many things on their own. Yet it's always good to learn that some website security colleagues will help one another by teaching (in all forms such as blogging).

Some small website owners don't think they're worthy of any hacker's time. This is dead wrong. Your website might be beneficial in making it a channel to another bigger malware plague. The majority of website security breaches are not to steal your data or deface your website, but instead attempts to use your server as an email relay for spam, or to setup a temporary web server, normally to serve files of an illegal nature. Other very common ways to abuse compromised machines include using your servers as part of a botnet, or to mine for Bitcoins. You could even be hit by ransomware.

Five Common Web Security Issues are:

Here's a brief list of the common web security issues that weakens websites:

  1. Cross Site Scripting (XSS)
  2. Injection Mistakes
  3. Outdated Security Configurations
  4. A Lost Function Level Access Control
  5. Exposing Sensitive Data
Five Common Web Security Issues

#1. Cross Site Scripting (XSS)

This is another form of injection vulnerability that can input sanitization failure. A hacker sets up your web application JavaScript tags on input. When this input is returned to the user unsanitized, the user's browser will carry it out. It can be as simple as creating a link and persuading a user to click it, or it can be something much more sinister. On page load the script runs and, for example, can be used to post your cookies to the hacker.

#2. Injection Mistakes

If you want a smooth filter of untrusted input, injections flaws must be avoided at all costs. An injection flaw can let you pass unfiltered data to the SQL server, to the browser, to the LDAP server (LDAP injection), or anywhere else. These website layers can be used by a hacker to inject commands. This can result in loss of data and hacking your own website. In fact, it can also infect other websites as well.

#3. Outdated Security Configurations

Any responsible website security personnel will always make sure to personalize your security settings such as passwords and authentications. Perhaps, some people are still human to miss important things in their jobs. Some concrete scenarios are:

  • They let the application run with debug enabled in production.
  • They didn't change default keys and passwords.
  • They left the directory listing enabled on the server, which leaks valuable information.
  • They allow unnecessary services running on the machine.
  • They operated an outdated software (think WordPress plugins, old PhpMyAdmin).
  • They didn't fix some pop-up messages on error information.

#4. A Lost Function Level Access Control

An authorization failure can also disrupt your website. It means that when a function is called on the server, proper authorization was not performed. A lot of times, website developers rely on the fact that the server side generated the UI. They think that the functionality that is not supplied by the server cannot be accessed by the client. It is not as easy as they thought, as a hacker can always fake requests to the "hidden" functionality and will not be prevented by the fact that the UI doesn't make this functionality easily accessible. Nothing can stop an attacker from discovering this functionality and abusing it if authorization is missing.

#5. Exposing Sensitive Data

It's a huge failure for website security personnel – to not encrypt and not protect your sensitive data. Information (such as credit card details) and user passwords should never travel or be stored unencrypted, and passwords should always be hashed. And while it goes without saying that session IDs and sensitive data should not be traveling in the URLs. Moreover, sensitive cookies should have a secure flag on them, this is very important and cannot be over-emphasized.
