When talking about cyber risks, the first thing you might think of is malware. However, many cyber-attacks are linked to apps. According to the Positive Technologies data, users can be attacked by hackers in 9 out of 10 web applications. Many attacks though, would be impossible without the weaknesses in the software that could be misused.
In order to improve the quality and security of applications, the community project “Open Web Application Security Project” (OWASP) was launched. There are various sub-projects within the OWASP, and one of them is the OWASP Top Ten Project, which describes the most critical vulnerabilities of web apps. In this blog, we provide a list of the most common errors related to application security. This information will help you to understand the most important aspects of building a secure app that users will trust.
Here are the top 10 web app vulnerabilities according to the OWASP data.
A simple failure to filter the untrusted inputs leads to the problem called injection flaws. Injection vulnerabilities, such as SQL, OS, or LDAP injection, occur when an interpreter processes untrustworthy data as part of a command or query. Attackers, therefore, have an opportunity to manipulate input data. More precisely, they can access data without authorization or even execute system commands.
This is quite a common vulnerability that refers to the set of various issues that might happen Access control error during broken authentication. Why does it occur? Developers often implement app functions related to authentication and session management incorrectly. This allows hackers to compromise passwords or session tokens or to exploit the corresponding vulnerabilities in such a way that they can temporarily or permanently impersonate other users.
Many apps do not adequately protect sensitive information, such as personal, financial, or health data.
