common vulnerabilities and exposures

Common Security vulnerabilities for ASPs ASP's vulnerability is already very small, want to find the actual location of the database is not simple, but this does not mean that hackers have no access to, it is this view, the general programmer often forget to carefully check whether there is a loophole, so that the site data can be stolen events occur. Today I am here to talk to you about the

, and so on, preventing attackers from using these error messages for some judgment. (8) It is recommended that some specialized SQL injection detection tools be used to detect and fix these SQL injection vulnerabilities before the website is published. Second, cross-site scripting vulnerability Cross-site scripting attacks (Cross-site scripting, often referred to as XSS) occur on the client side and can be used for attacks such as stealing priva

Php Basics, common vulnerabilities, and simple prevention. Common php attacks and security defense: 1. Xss + SQL injection: Xss protection for input: $ _ REQUEST = filter_xss ($ _ REQUEST); $ _ GET = filter_xss ($ _ GET); $ _ POST, $ _ COOKIE, SQL injection: Filter_ SQL (); The simplest xss function is htmlspecialchars; The simplest SQL function is mysql

messages, such as type errors, field mismatches, etc., to prevent attackers from using these error messages to make some judgments.(8) Before the launch of the website, it is recommended to use some professional SQL injection detection tools to detect and timely repair these SQL injection vulnerabilities. second, cross-site Scripting vulnerabilityCross-site scripting attacks (Cross-site scripting, often referred to as XSS) occur on the client s

Extremely dangerous and common website security vulnerabilities and Solutions Recently, I handled two security vulnerabilities in the company's Internet project, which are common and dangerous. I. reflected Cross-Site Scripting VulnerabilityVulnerability risks: Attackers can embed an Attack Script. Once the page is loa

During vulnerability assessment and penetration testing, we usually focus on operating system-level vulnerabilities and ultimately ignore Layer 7. This is a very dangerous trap because there are many attacks on remote logon and SSH Linux systems. In fact, in my opinion, most Linux-based defects are at the application layer. It may be Apache, PHP, or OpenSSL, or it is only a common error configuration. If th

Summary of common PHP code auditing vulnerabilities, simple things, and bad things. You are welcome to point out that continuous learning and research can make continuous progress and stick to it, you will understand it one day. 1. the SQL injection vulnerability may exist in all areas that interact with the database. 2. file Inclusion Vulnerability include/include_once/require/require_once 3. XSS Cross-Sit

later is used, or Outlook Express 6 SP1 or laterThen, read the mail message in plain text format to prevent HTML mail attacks. 7. Tool Manager VulnerabilityThe Tool Manager program allows users to check the status of the auxiliary program (such as a magnifier, screen keypad, voice Lang)And can start and stop these auxiliary programs. Because the manager uses system permissions when starting the Helper ProgramLocal users can use this program to obtain system management permissions. Temporary

Of course, not all program code security vulnerabilities are attributed to Web server software. For example, if you are using a typical installation of Widows NT Option Pack 4.0, the installer will install exploration Air, which is a Web application program that is available to ASP programmers as an example. The showcode.asp file of widows NT Option Pack 4.0 will display the original program code of the Exploration Air sample site neatly. Since there

With the increasing number of machines in Internet cafes, the application environment has become extremely complex. To facilitate cashier management, many bosses have adopted professional management software, to calculate the Internet access fees of all current users. Although the results are good, they cannot cover up the vulnerabilities in Internet cafes, and even they may cause a lot of trouble for network administrators. It can be seen that their

Today, with the rapid evolution of Web technology and the vigorous development of e-commerce, many new applications developed by enterprises are Web applications, in addition, Web services are increasingly used to integrate or interact with Web applications. These trends bring about the following problems: the growth of Web applications and services has exceeded the security training and security awareness received by program developers. The security risks of web application systems have reached

; Therefore, in order to improve the security of PHP programs, we cannot trust any variables that are not explicitly defined. If there are many variables in the program, this is a very difficult task. A common protection is to check the variables in the array http_get[] or post_vars[], depending on the way we commit (get or post). When PHP is configured to open the "track_vars" option (which is the default), the user-submitted variables can be obtaine
