The full form of OWASP is the Open Web Application Security Project. It is a non-profit group that helps a variety of organizations to develop, purchase, and maintain software applications that can be trusted. The educate developers, designers, architects, and business owners all are sought by OWASP to identify the risk associate with the most common web application security vulnerabilities. OWASP is known as a forum as it supports both open source and commercial security products in which information technology professionals can network and build expertise. The materials which are needed by the organizations are available for the free and open software license.
OWASP is the open call for data and best for industries and companies to perform secure code reviews, penetration testing, etc., and can send their data anonymously. For producing a frequency of each risk and each vulnerability, the data will be collated and assigned based on the score on its exploitability, prevalence, detectability, and technical impact.
The sensitive information can be leaked from verbose error messages and injection flaws can lead to major undesirable and disastrous outcomes. The injection flaws are not limited to SQL injection, LDAP injections, or file system injections. Since 2013 the injection flaws in the OWASP list occur when the applications enter into the user-supplied data which will pass onto the blackened database or server without proper input validation checks. The intention of the hacker is of exploiting the application so he/she will craft a string accordingly. Some remediation measures are:
Since 2013 just like injection, broken authentication also not changed its position in the OWASP top 10 vulnerabilities list. The attackers can impersonate legitimate users if the system authentication is misconfigured by compromising passwords, session tokens, etc. there will be a severe technical impact. You can potentially access all the resources of the website or application if you logged in like anybody else. Below are the remediation measures:
Most of the data related to financial information, health records, user credentials, etc., come under sensitive data, and in this vulnerability, this type of data should be usually encrypted or kept hidden so that it will be visible as plaintext. The hackers can access this information also by executing man-in-middle (MiM) and steal the data in transit. In the past several years, the exposure of sensitive data has become more common. Remuneration measures listed below:
XXE can get some benefit of the XML parsers in a web application and this might process and execute some of the load of payment that includes external reference in the XML document. The list that is based on statistics, this vulnerability is added in that and this statistics list is returned by the companies running static analysis tools. They have seen that in the last couple of years this vulnerability has steadily gained traction in XML processing and has become a more serious risk to web applications. Is these entities are added or modify by attackers in the XML files and the malicious source is pointed in them then they can cause a denial of service (DoS) attack or an SSRF attack. Listed below are the remuneration measures –
There are two categories in the OWASP vulnerability list named as Missing function level access control and insecure direct object references. Both are merged into broken access control in the OWASP’s latest published list. The weakness in the access control system is referred to as Broken access control and this will allow attackers to gain access as privileged users through bypass authorization. Some remediation measures are –
In this category, there is a wide variety of improper implementation that keeps the application data safe. There are various things like misconfiguring security headers, verbose error message ignoring that can leak sensitivity information, patch or upgrade system neglecting, etc. Remediation measures are discussed below –
Cross-site scripting lost its position from third to seventh place in the OWASP top 10 vulnerability list. It is just because other vulnerabilities have gained more precedence. Still, it is one of the common vulnerabilities that affects more than two-thirds of the applications. Some remediation measures are listed below –
The serialization content is an object from the application code and it is converting it into a stream of bytes. Deserialization is just the opposite of it which refers to serialized data converting back into the objects usable by the application. Remediation measures listed below –
This section is mainly referring to the widespread issue for using the various components like the implementation of libraries to a certain functionality without verifying their first legitimacy. The score of exploitability is variable and depends on what and where the vulnerability is. Some of the remediation measures are –
The organizations need to log events to detect data breaches in the interesting context of their application. The recording of occurrence of an event or security incidence in the web application is known as Logging. For example – repeated failed login attempts for the same IP. The continually keeping an eye on these logs that can escalate to the incidence response (IR) team for timely action is known as Monitoring. Remediation measures are –
