Configuration Management / Content Sniffing Not Disabled
Content Sniffing not disabled is a Configuration Management vulnerability that occurs in Web and API applications. It is a type of attack that attempts to exploit potential security flaws in web applications by exploiting the client's ability to interpret data sent from the server. Content Sniffing not disabled can allow attackers to execute malicious code on a vulnerable system through a process known as Cross-Site Scripting (XSS). It is a form of injection attack where the attacker injects malicious code into the server and uses the server's content sniffing mechanism to execute the code. It is also known as Cross-Browser Scripting (CBS). (Reference: OWASP Testing Guide)
Content Sniffing not disabled is considered to be a serious risk as it can allow an attacker to execute malicious code on a vulnerable system. This can lead to the compromise of sensitive data, unauthorized access, and the disruption of operations. The risk assessment for Content Sniffing not disabled is high, as it can lead to a significant security breach.
The best way to protect against Content Sniffing not disabled is to ensure that the web application is configured to disable content sniffing. This can be done by setting the X-Content-Type-Options header to "nosniff". This will prevent browsers from attempting to interpret data sent from the server, and thus, prevent attackers from exploiting the vulnerability.
