A directory traversal (or path traversal) attack exploits insufficient security validation or sanitization of user-supplied file names, such that characters representing "traverse to parent directory" are passed through to the operating system's file system API. An affected application can be exploited to gain unauthorized access to the file ...
Attacks were launched by placing malicious, automatic-action HTML image elements on forums and email spam, so that browsers visiting these pages would open them automatically, without much user action. People running vulnerable uTorrent version at the same time as opening these pages were susceptible to the attack.
A file inclusion vulnerability is a type of web vulnerability that is most commonly found to affect web applications that rely on a scripting run time.This issue is caused when an application builds a path to executable code using an attacker-controlled variable in a way that allows the attacker to control which file is executed at run time.
An example of a DOM-based XSS vulnerability is the bug found in 2011 in a number of jQuery plugins. [16] Prevention strategies for DOM-based XSS attacks include very similar measures to traditional XSS prevention strategies but implemented in JavaScript code and contained in web pages (i.e. input validation and escaping). [17]
Detection of drive-by download attacks is an active area of research. Some methods of detection involve anomaly detection, which tracks for state changes on a user's computer system while the user visits a webpage. This involves monitoring the user's computer system for anomalous changes when a web page is rendered.
In an HTTP flood, the HTTP clients such as web browser interact with an application or server to send HTTP requests. The request can be either “GET” or “POST”. The aim of the attack is when to compel the server to allocate as many resources as possible to serving the attack, thus denying legitimate users access to the server's resources.
A symlink race can happen with antivirus products that decide they will quarantine or delete a suspicious file, and then go ahead and do that. During the interval between decision and action, malicious software can replace the suspicious file with a system or antivirus file that the malicious software wants overwritten. [2]
An extension of the collision attack is the chosen-prefix collision attack, which is specific to Merkle–Damgård hash functions.In this case, the attacker can choose two arbitrarily different documents, and then append different calculated values that result in the whole documents having an equal hash value.
