This article explains what server‑side template injection (SSTI) is, how it arises, its potential impacts such as remote code execution, methods for detecting, identifying and exploiting vulnerable template engines, and best‑practice mitigation techniques to prevent these critical web security flaws.
This article explains the fundamentals of Cross‑Site Request Forgery (CSRF), illustrates typical attack scenarios and payloads, and details multiple defense strategies including CSRF tokens, SameSite cookies, and best‑practice validation techniques for web.
This article explains what insecure deserialization is, why it leads to high‑severity attacks, demonstrates typical PHP, Ruby, and Java examples, and provides practical techniques for identifying, exploiting, and mitigating unsafe deserialization vulnerabilities.
This article explains what the Document Object Model (DOM) is, describes how unsafe handling of DOM sources and sinks leads to vulnerabilities such as XSS, open redirection, and DOM clobbering, and provides practical mitigation techniques and defensive coding practices.
This article explains how misconfigured HTTP Host headers can be abused for attacks such as cache poisoning, SSRF, password‑reset poisoning and other server‑side exploits, and provides practical detection methods and defensive recommendations for developers and security engineers.
This article explains what clickjacking (UI redressing) is, demonstrates how attackers craft hidden iframe layers to hijack user clicks, and outlines both client‑side and server‑side mitigation strategies such as frame‑busting scripts, X‑Frame‑Options, and Content‑Security‑Policy directives.
This article explains what HTTP request smuggling is, how the vulnerability arises from conflicting Content‑Length and Transfer‑Encoding headers, describes common CL.TE, TE.CL and TE.TE attack patterns, and outlines detection techniques and defensive measures for modern web infrastructures.
This article explains what OS command injection is, how it can be detected and exploited on both Linux and Windows systems, demonstrates common payloads and techniques—including blind and out‑of‑band methods—and provides best‑practice defenses to prevent such vulnerabilities.
This article explains what server‑side request forgery (SSRF) is, describes its impact, common attack vectors such as targeting the server itself or internal services, outlines bypass techniques for blacklist and whitelist filters, and discusses blind SSRF detection using out‑of‑band methods.
This article explains what directory (path) traversal is, demonstrates how attackers can read or write arbitrary files on a server by manipulating file‑path parameters, outlines common bypass techniques, and provides concrete defensive coding practices to mitigate the vulnerability.
