Background for this topic.
An exploit is code, data, or a sequence of actions that uses a software, hardware, or configuration vulnerability to produce unintended behavior. Depending on the flaw and the attacker’s access, it may enable unauthorized code execution, privilege escalation, information disclosure, or denial of service. Exploitation can occur remotely through exposed services, web applications, or client software, or locally after an attacker gains limited access.
Exploitation matters because a vulnerability becomes an active attack path when the required conditions are reachable and exploitable. Defenders should inventory affected assets, prioritize remediation when exploitation is known or credible, apply patches or vendor mitigations, and reduce exposure through access controls, segmentation, and secure configuration. Monitoring for exploit-specific indicators—such as abnormal requests, unexpected processes, or privilege changes—supports detection; systems suspected of successful exploitation require containment and investigation for follow-on access.

Modern web app development relies on cloud infrastructure and containerization. These technologies scale on demand, handling millions of daily file transfers – it's almost impossible to imagine a world without them. However, they also introduce multiple attack vectors that exploit file uploads when working with public clouds, vulnerabilities in containers hosting web applications, and many other
