HTTP Parameter Pollution (HPP) is a web application vulnerability exploited by injecting encoded query string delimiters in already existing parameters. The vulnerability occurs if user input is not correctly encoded for output by a web application. [1] This vulnerability allows the injection of parameters into web application-created URLs.
w3af (Web Application Attack and Audit Framework) is an open-source web application security scanner. The project provides a vulnerability scanner and exploitation tool for Web applications. [ 2 ] It provides information about security vulnerabilities for use in penetration testing engagements.
A VDB will assign a unique identifier to each vulnerability cataloged such as a number (e.g. 123456) or alphanumeric designation (e.g. VDB-2020-12345). Information in the database can be made available via web pages, exports, or API. A VDB can provide the information for free, for pay, or a combination thereof.
The Damn Vulnerable Web Application is a software project that intentionally includes security vulnerabilities and is intended for educational purposes. [ 1 ] [ 2 ] [ 3 ] Examples
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:
It also provides the Cloud Property Graph, [19] an extension of the code property graph concept that models details of cloud deployments. Galois’ CPG for LLVM. Galois Inc. provides a code property graph based on the LLVM compiler. [20] The graph represents code at different stages of the compilation and a mapping between these representations.
A hacker trying to take control of a website's database might use such an attack string to manipulate a website into running malicious code. Injection attacks are one of the most common vectors by which a database breach can occur; they are the top most common web application vulnerability on the OWASP Top 10 list. [26]
Though Active Server Pages, ASP.NET, Python, Perl, Ruby, and Unix shell scripts are also used. [1] [2] [3] Using network monitoring tools, an attacker can find vulnerabilities that can potentially allow delivery of a web shell. These vulnerabilities are often present in applications that are run on a web server. [2]
