What is DOM ? The Document Object Model ( DOM ) is a cross-platform and language-independent application programming interface that treats a HTML, XHTML, or XML document as a tree structure wherein each node is an object representing a part of the document. The objects can be manipulated programmatically and any visible changes occurring as a result may then be reflected in the display of the document. The principal standardization of DOM was handled by the World Wide Web Consortium, which last developed a recommendation in 2004. WHATWG took over development of the standard, publishing it as a living document. The W3C now publishes stable snapshots of the WHATWG standard. History The history of the Document Object Model is intertwined with the history of the "browser wars" of the late 1990s between Netscape Navigator and Microsoft Internet Explorer, as well as with that of JavaScript and JScript, the first scripting languages to be widely implemented in the

If your System has primary OS Windows then you install your secondary OS Kali Linux. That will be OK, Kali Linux puts boot entry of Windows automatically for you. At initial boot menu you can see both OS entry to boot. If your windows is corrupt in dual boot system or if you want to install windows as secondary OS after installing Kali Linux as primary OS. You may face corrupt boot-loader menu. You wont be able to boot Kali Linux any more because Windows wont put entry of Kali Linux automatically in their boot menu. So this post motive is to help those guys which are facing those problems subjecting to corrupt Boot-loader. There are mainly two methods: 1. Repair Grub via Kali Linux live USB. 2. Repair Grub Via Boot-rapair-disk. Method 1# Repair Grub via Kali Linux live USB It is up to you which you want to choose but if you are Linux familiar then go for this method. Requirements 1. A Kali Linux ISO image. You can download here: Download Kali Linux

HTML injection is a type of injection issue that occurs when a user is able to control an input point and is able to inject arbitrary HTML code into a vulnerable web page. This vulnerability can have many consequences, like disclosure of a user's session cookies that could be used to impersonate the victim, or, more generally, it can allow the attacker to modify the page content seen by the victims. How to Test This vulnerability occurs when the user input is not correctly sanitized and the output is not encoded. An injection allows the attacker to send a malicious HTML page to a victim. The targeted browser will not be able to distinguish (trust) the legit from the malicious parts and consequently will parse and execute all as legit in the victim context. There is a wide range of methods and attributes that could be used to render HTML content. If these methods are provided with an untrusted input, then there is an high risk of XSS, specifically an HTML injection one. M

Similar to SQL Injection , XPath Injection attacks occur when a web site uses user-supplied information to construct an XPath query for XML data. By sending intentionally malformed information into the web site, an attacker can find out how the XML data is structured, or access data that he may not normally have access to. He may even be able to elevate his privileges on the web site if the XML data is being used for authentication (such as an XML based user file). Querying XML is done with XPath, a type of simple descriptive statement that allows the XML query to locate a piece of information. Like SQL, you can specify certain attributes to find, and patterns to match. When using XML for a web site it is common to accept some form of input on the query string to identify the content to locate and display on the page. This input must be sanitized to verify that it doesn't mess up the XPath query and return the wrong data. XPath is a standard language; its notation/sy

DUHK — Don't Use Hard-coded Keys — is a new 'non-trivial' cryptographic implementation vulnerability that could allow attackers to recover encryption keys that secure VPN connections and web browsing sessions. DUHK is the third crypto-related vulnerability reported this month after KRACK Wi-Fi attack and ROCA factorization attack. The vulnerability affects products from dozens of vendors, including Fortinet, Cisco, TechGuard, whose devices rely on ANSI X9.31 RNG — an outdated pseudorandom number generation algorithm — 'in conjunction with a hard-coded seed key.' Before getting removed from the list of FIPS-approved pseudorandom number generation algorithms in January 2016, ANSI X9.31 RNG was included into various cryptographic standards over the last three decades. Pseudorandom number generators (PRNGs) don’t generate random numbers at all. Instead, it is a deterministic algorithm that produces a sequence of bits based on initial secret values called a seed and t

A new widespread ransomware worm, known as "Bad Rabbit," that hit over 200 major organisations, primarily in Russia and Ukraine this week leverages a stolen NSA exploit released by the Shadow Brokers this April to spread across victims' networks. Earlier it was reported that this week's crypto-ransomware outbreak did not use any National Security Agency-developed exploits, neither EternalRomance nor EternalBlue, but a recent report from Cisco's Talos Security Intelligence revealed that the Bad Rabbit ransomware did use EternalRomance exploit. NotPetya ransomware (also known as ExPetr and Nyetya) that infected tens of thousands of systems back in June also leveraged the EternalRomance exploit, along with another NSA's leaked Windows hacking exploit EternalBlue, which was used in the WannaCry ransomware outbreak. Bad Rabbit Uses EternalRomance SMB RCE Exploit Bad Rabbit does not use EternalBlue but does leverage EternalRomance RCE expl

A highly critical vulnerability has been discovered in Oracle's enterprise identity management system that can be easily exploited by remote, unauthenticated attackers to take full control over the affected systems. The critical vulnerability tracked as CVE-2017-10151, has been assigned the highest CVSS score of 10 and is easy to exploit without any user interaction, Oracle said in its advisory published Monday without revealing many details about the issue. The vulnerability affects Oracle Identity Manager (OIM) component of Oracle Fusion Middleware—an enterprise identity management system that automatically manages users' access privileges within enterprises. The security loophole is due to a "default account" that an unauthenticated attacker over the same network can access via HTTP to compromise Oracle Identity Manager. Oracle has not released complete details of the vulnerability in an effort to prevent exploitation in the wild, but here the "

A SQL injection attack consists of insertion or "injection" of a SQL query via the input data from the client to the application. A successful SQL injection exploit can read sensitive data from the database, modify database data (Insert/Update/Delete), execute administration operations on the database (such as shutdown the DBMS), recover the content of a given file present on the DBMS file system and in some cases issue commands to the operating system. SQL injection attacks are a type of injection attack, in which SQL commands are injected into data-plane input in order to effect the execution of predefined SQL commands. SQL Injection – Basic Concepts There are two types of SQL Injection • SQL Injection into a String/Char parameter Example: SELECT * from table where example = 'Example' • SQL Injection into a Numeric parameter Example: SELECT * from table where id = 123 Exploitation of SQL Injection vulnerabilities is divided into classes a

With the growing number of cyber attacks and data breaches, a number of tech companies and organisations have started Bug Bounty programs for encouraging hackers, bug hunters and researchers to find and responsibly report bugs in their services and get rewarded. Samsung is the latest in the list of tech companies to launch a bug bounty program, announcing that the South Korean electronics giant will offer rewards of up to $200,000 to anyone who discovers vulnerabilities in its mobile devices and associated software. Dubbed Mobile Security Rewards Program , the newly-launched bug bounty program will cover 38 Samsung mobile devices released from 2016 onwards which currently receive monthly or quarterly security updates from the company. Conditions for rewards qualification: 1. Security vulnerability report ("Report") must be applicable to eligible Samsung Mobile devices, services, applications developed and signed by Samsung Mobile, or elig
