If a redirect target is not sufficiently validated by a web application, an attacker can make a web application redirect to an arbitrary website. This vulnerability is known as an open-redirect vulnerability. [26] [27] In certain cases when an open redirect occurs as part of an authentication flow, the vulnerability is known as a covert redirect.
HTTP response splitting is a form of web application vulnerability, resulting from the failure of the application or its environment to properly sanitize input values.It can be used to perform cross-site scripting attacks, cross-user defacement, web cache poisoning, and similar exploits.
The malicious code is known to be in 5.6.0 and 5.6.1 releases of the XZ Utils software package. The exploit remains dormant unless a specific third-party patch of the SSH server is used. Under the right circumstances this interference could potentially enable a malicious actor to break sshd authentication and gain unauthorized access to the ...
Logo. The Common Vulnerabilities and Exposures (CVE) system provides a reference method for publicly known information-security vulnerabilities and exposures. [1] The United States' National Cybersecurity FFRDC, operated by The MITRE Corporation, maintains the system, with funding from the US National Cyber Security Division of the US Department of Homeland Security.

Code injection is the malicious injection or introduction of code into an application. Some web servers have a guestbook script, which accepts small messages from users and typically receives messages such as: Very nice site! However, a malicious person may know of a code injection vulnerability in the guestbook and enter a message such as:
The attacker must target either a site that doesn't check the referrer header or a victim with a browser or plugin that allows referer spoofing. [21] The attacker must find a form submission at the target site, or a URL that has side effects, that does something (e.g., transfers money, or changes the victim's e-mail address or password).
The CCS Injection Vulnerability (CVE-2014-0224) is a security bypass vulnerability that results from a weakness in OpenSSL methods used for keying material. [80] This vulnerability can be exploited through the use of a man-in-the-middle attack, [81] where an attacker may be able to decrypt and modify traffic in transit. A remote unauthenticated ...
On its own, an arbitrary code execution exploit will give the attacker the same privileges as the target process that is vulnerable. [11] For example, if exploiting a flaw in a web browser, an attacker could act as the user, performing actions such as modifying personal computer files or accessing banking information, but would not be able to perform system-level actions (unless the user in ...
