The Open Web Application Security Project (OWASP), of which Fluid Attacks is a corporate member, is a non-profit foundation that through different means of communication is committed to improving the security of software. The OWASP works as an online, open community where anyone can contribute to the production of material in the field of web application security and also take advantage of the available information. Their repository is useful for companies that develop or manage web applications, since it relies on the knowledge of many global community members with extensive experience in cybersecurity.
The OWASP Top 10 refers to a cybersecurity guide by the OWASP community that is created in agreement between experts and serves both developers and security professionals in their projects. This guide, with a current version from 2017, lists the ten most common and critical security risks in web applications and provides practical information for their prevention or remediation.
The idea with this ranking is to help reduce the presence of flaws in web applications that can be easily exploited and generate terrible impact. Organizations should always be careful not to bring into production applications with vulnerabilities related to these security risks, making sure to pay attention to the most prevalent risks in their specific industry sector. Here we show you the current list of risks with a brief description of each one (for more information see the official report):
A code injection occurs when an application does not properly validate or sanitize input and this can be leveraged to make it process the input as code.
Attackers can take advantage of misconfigured session authentication and management functions in the applications and compromise passwords, sessions, and even entire systems.
This problem occurs when applications do not have sufficient protection for sensitive data (e.g., financial data), leaving it publicly accessible or without adequate access controls that prevent attackers from obtaining it for illegal activities.
In this case, attackers exploit weak configurations in a web application that parses XML input but does not properly handle references to external entities, which can be used to exfiltrate documents, execute code remotely or perform denial-of-service attacks.
Web applications need to establish limits for the access to data and functions depending on the type of user. Here, the attackers circumvent misconfigured (sometimes simply non-existent) access restrictions and can operate as any user, including administrators.
This misconfiguration refers to the inappropriate implementation of controls for the application’s security, resulting in the exposure of error messages containing sensitive data and the use of non-updated systems or components.
Attackers can inject client-side scripts into the web application to change its behavior, modify what is displayed to the users or redirect the users to malicious websites.
Deserialization, the opposite process to serialization, consists in converting strings of bytes into data structures that the application can use. Deserialization weaknesses allow the attacker to execute code in the web application remotely and manipulate serialized objects as desired.
Web applications commonly use various open-source and third-party components in which vulnerabilities are sometimes found and need to be patched. Keeping outdated versions of those components with known vulnerabilities leads to having an application exposed to exploitation.
Many companies do not frequently log and monitor their applications’ activities. Usually, data breaches are detected after months, when the attackers have already done a lot of damage.
Ensuring compliance with up-to-date security standards may become a complicated issue for diverse organizations that use continually evolving information technology for their businesses. Fluid Attacks recognizes this and offers you comprehensive testing and analysis to determine whether your company is effectively complying with all corresponding security requirements.
Although Fluid Attacks’ Continuous Hacking service goes beyond the OWASP Top 10 Web Application Security Risk, testing around 200 technical security requirements in each of your projects, we can guarantee the detection of all vulnerabilities in your software associated with such risks. In addition, we provide you with reliable reports so that your team can take the necessary steps to adjust and maintain your information systems in line with such requirements.
All our security testing is based on Rules, which is a set of security requirements written by us in a comprehensible manner, using several international standards as a reference. It allows you to parameterize the assessments we make to your systems and determine what your company agrees to comply with and what would be considered a vulnerability.
