Security Vulnerabilities Most Commonly Found In Todayโ€™s Websites


Over the past fifteen years, the way the internet has evolved and advanced is like a tech geekโ€™s wildest dream come true. From commanding the office printer to print a file from anywhere in the office to todayโ€™s gigabit speeds that allow us to create, access or add almost any type of content we want. The Internet has come a long way.Unfortunately, all good things have a dark side too and so does the internet. From unintentional bugs and glitches to malware and spyware, internetโ€™s dark side can be pretty damaging. The scariest thing about cyber threats is that as the internet evolves and newer technologies are introduced, cyber attacks will only get more sophisticated.Cyber attacks cannot be predicted but they can definitely be prepared for. It is just people on the other side of these damaging transmissions and just like us, they also make mistakes. If you take the right precautions and measures, you will not only succeed in successfully evading any cyber attacks but you can also find out who tried attacking you.

Classifying security vulnerabilities

Experts from PHP development company London tell us security vulnerabilities are prioritized and classified depending on their exploitability, detectability and the level of damage they can cause. Here is a breakdown;
  • Exploitability; What materials are needed to exploit the vulnerability? And, how easy is it to exploit the vulnerability? Needing only a web browser for exploitation is considered the highest level of exploitability while needing advanced programming and related tools is considered the lowest level of exploitability.
  • Detectability; Is the vulnerability obvious? How easy would it be for an attacker to detect that vulnerability? The vulnerability being detectable from the information in the URL bar or an error message is the highest level of detectability while the lowest level is having the find it in the source code.
  • Level of impact/damage; If the security vulnerability is exploited, can it cause damage? How serious will the damage be if the vulnerability is exploited? The highest level of damage is a system crash while the lowest level is no damage at all.

Todayโ€™s most common web security vulnerabilities

Now that you know just how cybersecurity experts decide how big or important a security vulnerability is, itโ€™s time to talk about some of the most common web security vulnerabilities of today. Hereโ€™s what has been bothering all the IT departments in the world lately;

Plug-in vulnerabilities

Third-party plug-ins usually have some glitches that an attacker can exploit in order to attack your website. The best way to keep your website safe from such glitches is to always keep your plug-ins updated.If your website is being handled by a web development company, make sure that they are keeping all plug-ins up to date. Also, sometimes when a plug-in gets a major update, it can bring along a new glitch.Itโ€™s important that you or whoever is handling your website keeps an eye on new updates. If a plug-in update opens up a big vulnerability, it is best not to update and if you already have, go back to using an older version until the new version is patched.

Default login Credentials

There are a lot of people involved in the making of a website. That means, your website login credentials can easily get leaked which a person can then use to hold your website hostage. Always use a complex, at least 12 figures long, login username and password.If your website was created by web development house, the first thing to do once you get your login credentials is to change them. Use long and complex passwords and if you have trouble remembering passwords use a password bank like LastPass. Just donโ€™t write down your login credentials on a piece of paper. Ever!

Vulnerable host servers

PHP developers London tell us that hosting servers can be attacked as well. And, if the hosting providers have not taken enough security precautions, the attackers can quite easily gain access to your website.To ensure your hosting servers stay safe always follow the latest security precautions. Itโ€™s also good to stay up to date about the kind of threats that could pose a danger to your hosting servers. And needless to say, scan your hosting servers every few hours to ensure everything is in order.

SQL injection

SQL InjectionThis is one of the most dangerous vulnerabilities of current times. What an โ€œinjectionโ€ does is that it allows an attacker to manipulate or alter the SQL commands running in the background by manipulating the data supplied via user.โ€œInjectionโ€ takes place when the manipulated user-supplied data is taken to the system for processing and there, it tricks the system into executing unintended commands. The execution of these commands can result in the attacker gaining access to unauthorized data. This vulnerability has also been shown to provide the attacker with back-end database access.

Insecure direct object references

Insecure direct object references can occur when a developer or someone who has back-end access to the website, exposes a direct reference to an implementation object. The reference can be to a file, a directory, database key, etc and can be in the form of URL or FORM parameter.An attacker can use this data to access other unauthorized data and objects on the website and that data can be used to create a future attack to gain access to even more unauthorized data.


There you have it, folks. These are some of the most common security vulnerabilities faced by todayโ€™s websites. Security can be a tricky thing as it requires resources and effort but, without foolproof security, no data can ever remain safe and secure.The internet has become an integral and an irreplaceable part of our lives now. And with cyber threats becoming more and more dangerous, it has become necessary for all of us to learn about them so that we are fully prepared when an inevitable attack comes.
