CSRF is a security vulnerability that tricks a victim into performing unintended actions on a web application where they are authenticated. By exploiting the trust that a website places in the user’s browser, attackers can force users to execute actions without their consent or knowledge.
SQL Injection is a code injection technique that exploits a software vulnerability within the database query layer. This occurs when an application does not properly sanitise or neutralise special elements in SQL statements. Attackers craft malicious inputs to manipulate queries, gaining unauthorised access to databases or manipulating data.
At its core, **security misconfiguration** occurs when the security settings of an API or its supporting systems are improperly configured or left at their default settings. APIs often rely on a wide range of underlying infrastructure, including web servers, databases, cloud services, and identity management systems. Each of these elements needs to be configured in line with security best practices to ensure the overall security posture of the API.
Misconfigurations can arise at any stage in the API lifecycle, from development to deployment, and they are not limited to a single type of vulnerability. They may involve poorly configured authentication mechanisms, incorrect access control settings, or vulnerabilities in third-party services integrated into the API ecosystem.
SSRF vulnerabilities occur when an API fetches a remote resource using a user-supplied Uniform Resource Identifier (URI) without adequate validation. This oversight allows attackers to manipulate the request, coercing the server to interact with unintended destinations. These attacks bypass traditional network controls like firewalls and VPNs, making them particularly insidious.
HTTP Response Splitting is a web application vulnerability that occurs when an attacker is able to manipulate HTTP headers to split the response sent to the client. This manipulation exploits the way headers are processed by web servers and browsers, allowing attackers to inject malicious content into the response stream. The result can be a range of attacks, from cross-site scripting (XSS) to cache poisoning and web cache poisoning, all of which can disrupt business operations, damage brand reputation, and compromise sensitive data.
