  • Recently, as modern Internet uses mashups, Web 3.0, JavaScript/AJAX widely, the rate at which new vulnerabilities are being discovered is increasing rapidly. It can subsequently introduce big security threats. In order to efficiently mitigate these web application vulnerabilities and security threats, it is needed to rank vulnerabilities based on severity and consider the severe vulnerabilities during a specific phase of software development lifecycle (SDLC) for web applications. In this paper, we have first verified whether the risk rating methodology of OWASP Top 10 vulnerabilities is a reasonable one or not by analyzing the vulnerability data of web applications in the US National Vulnerability Database (NVD). Then, by inspecting the vulnerability information of web applications based on OWASP Top-10 2010 list and CWE (Common Weakness Enumeration) directory, we have mapped the web-related entries of CWE onto the entries of OWASP Top-10 2010 and prioritized them. We have also presented which phase of SDLC is associated with each vulnerability entry. Using this approach, we can prevent or mitigate web application vulnerabilities and security threats efficiently.

  • Carriage return (CR) and line feed (LF), also known as CRLF injection is a type of vulnerability that allows a hacker to enter special characters into a web application, altering its operation or confusing the administrator. Log poisoning and HTTP response splitting are two prominent harmful uses of this technique. Additionally, CRLF injection can be used by an attacker to exploit other vulnerabilities, such as cross-site scripting (XSS). Email injection, also known as email header injection, is another way that can be used to modify the behavior of emails. The Open Web Application Security Project (OWASP) is an organization that studies vulnerabilities and ranks them based on their level of risk. According to OWASP, CRLF vulnerabilities are among the top 10 vulnerabilities and are a type of injection attack. Automated testing can help to quickly identify CRLF vulnerabilities, and is particularly useful for companies to test their applications before releasing them. However, CRLF vulnerabilities can also lead to the discovery of other high-risk vulnerabilities, and it fosters a better approach to mitigate CRLF vulnerabilities in the early stage and help secure applications against known vulnerabilities. Although there has been a significant amount of research on other types of injection attacks, such as Structure Query Language Injection (SQL Injection). There has been less research on CRLF vulnerabilities and how to detect them with automated testing. There is room for further research to be done on this subject matter in order to develop creative solutions to problems. It will also help to reduce false positive alerts by checking the header response of each request. Security automation is an important issue for companies trying to protect themselves against security threats. Automated alerts from security systems can provide a quicker and more accurate understanding of potential vulnerabilities and can help to reduce false positive alerts. Despite the extensive research on various types of vulnerabilities in web applications, CRLF vulnerabilities have only recently been included in the research. Utilizing automated testing as a recurring task can assist companies in receiving consistent updates about their systems and enhance their security.

  • Many companies have struggled to manage Web vulnerabilities and security incidents have also frequently happened. The current inspection methods are mainly based on the OWASP vulnerabilities. In practice, however, it is very difficult to cope with frequent changes of Web applications. In this paper, we first investigate the existing quantification of Web application vulnerabilities and verification process. Then we propose an improved inspection framework which is focused on removing essential and realistic vulnerabilities and active verification process.

  • In this paper, we evaluated web security vulnerability and privacy information management of hospital web sites which are registered at the Korea Hospital Association. Vulnerability Scanner (WVS) based on the OWASP Top 10 was used to evaluate the web security vulnerability of the web sites. And to evaluate the privacy information management, we used ten rules which were based on guidelines for protecting privacy information on web sites. From the results of the evaluation, we discovered tertiary hospitals had relatively excellent web security compared to other type of hospitals. But all the hospital types had not only high level vulnerabilities but also the other level of vulnerabilities. Additionally, 97% of the hospital web sites had a certain level of vulnerability, so a security inspection is needed to secure the web sites. We discovered a few SQL Injection and XSS vulnerabilities in the web sites of tertiary hospitals. However, these are very critical vulnerabilities, so all hospital types have to be inspected to protect their web sites against attacks from hacker. On the other hand, the inspection results of the tertiary hospitals for privacy information management had a better compliance rate than that of the other hospital types.

  • The smart factory has spread to small and mid-size enterprises (SMEs) under the leadership of the government. Smart factory consists of a work area, an operation management area, and an industrial control system (ICS) area. However, each site is combined with the IT system for reasons such as the convenience of work. As a result, various breaches could occur due to the weakness of the IT system. This study seeks to discover the items and vulnerabilities that SMEs who have difficulties in information security due to technology limitations, human resources, and budget should first diagnose and check. First, to compare the existing domestic and foreign smart factory vulnerability classification systems and improve the current classification system, the latest smart factory vulnerability information is collected from NVD, CISA, and OWASP. Then, significant keywords are extracted from pre-processing, co-occurrence network analysis is performed, and the relationship between each keyword and vulnerability is discovered. Finally, the improvement points of the classification system are derived by mapping it to the existing classification system. Therefore, configuration and maintenance, communication and network, and software development were the items to be diagnosed and checked first, and vulnerabilities were denial of service (DoS), lack of integrity checking for communications, inadequate authentication, privileges, and access control in software in descending order of importance.

  • The Structured Query Language (SQL) Injection continues to be one of greatest security risks in the world according to the Open Web Application Security Project's (OWASP) [1] Top 10 Security vulnerabilities 2013. The ease of exploitability and severe impact puts this attack at the top. As the countermeasures become more sophisticated, SOL Injection Attacks also continue to evolve, thus thwarting the attempt to eliminate this attack completely. The vulnerable data is a source of worry for government and financial institutions. In this paper, a detailed survey of different types of SQL Injection and proposed methods and theories are presented, along with various tools and their efficiency in intercepting and preventing SQL attacks.

  • OWASP announced most of vulnerabilities result from the data injection by user in 2010 after 2007. Because the contaminated input data is determined at runtime, those data should be checked dynamically. To analyze data and its flow at runtime, dynamic analysis method usually inserts instrument into source code. Intermediate code insertion makes it difficult to manage and extend the code so that the instrument code would be spreaded out according to increase of analysis coverage and volume of code under analysis. In addition, the coupling gets strong between instrument modules and target modules. Therefore developers will struggle against modify or extend the analysis code as instrument. To solve these problem, this paper defines vulnerabilities as a concern using AOP, and suggest the flexible and extensible analysis method to insertion and deletion without increase of coupling.

  • Today we live in a flood of web sites and access numerous websites through the Internet to obtain various information. However, unless the security of the Web site is secured, Web site security can not be secured from various malicious attacks. Hacking attacks, which exploit Web site security vulnerabilities for various reasons, such as financial and political purposes, are increasing. Various attack techniques such as SQL-injection, Cross-Site Scripting(XSS), and Drive-By-Download are being used, and the technology is also evolving. In order to defend against these various hacking attacks, it is necessary to remove the vulnerabilities from the development stage of the website, but it is not possible due to various problems such as time and cost. In order to compensate for this, it is important to identify vulnerabilities in Web sites through web vulnerability checking and take action. In this paper, we investigate web vulnerabilities and diagnostic techniques and try to understand the priorities of vulnerabilities in the development stage according to the actual status of each case through cases of actual web vulnerability diagnosis.
