A reflected attack is typically delivered via email or a neutral web site. The bait is an innocent-looking URL, pointing to a trusted site but containing the XSS vector. If the trusted site is vulnerable to the vector, clicking the link can cause the victim's browser to execute the injected script.
An XSS worm, sometimes referred to as a cross site scripting virus, [1] is a malicious (or sometimes non-malicious) payload, usually written in JavaScript, that breaches browser security to propagate among visitors of a website in the attempt to progressively infect other visitors. [2]
In computing and telecommunications, the payload is the part of transmitted data that is the actual intended message. Headers and metadata are sent only to enable payload delivery [1] [2] and are considered overhead. In the context of a computer virus or worm, the payload is the portion of the malware which performs malicious action.
Cache-timing attacks rely on the ability to infer hits and misses in shared caches on the web platform. [54] One of the first instances of a cache-timing attack involved the making of a cross-origin request to a page and then probing for the existence of the resources loaded by the request in the shared HTTP and the DNS cache.
Any function that can be used to compose and run a shell command is a potential vehicle for launching a shell injection attack. Among these are system(), StartProcess(), and System.Diagnostics.Process.Start(). Client-server systems such as web browser interaction with web servers are potentially vulnerable
Double URI-encoding is usually used as an attack technique against web applications and web browsers to bypass authorization schemes and security filters that intercept user input. [10] [11] For example because . and its URI-encoded form %2E are used in some directory traversal attacks, they are usually treated as illegal by security filters. [12]
Unlike web applications, they interact directly with a user's operating system. Common vulnerabilities in these applications include: [27] Unencrypted data that is in permanent storage or sent over a network is relatively easy for attackers to steal. [27] Process hijacking occurs when an attacker takes over an existing computer process. [27]
Self-XSS (self cross-site scripting) is a type of security vulnerability used to gain control of victims' web accounts. In a Self-XSS attack, the victim of the attack runs malicious code in their own web browser, thus exposing personal information to the attacker.
