Just Released WordPress Under Attack – Know Zero Day Vulnerability

The WordPress is used for content management around world by millions of websites that are vulnerable to two newly found threats. It allows the online hackers to full access control on your WordPress of the web server. However, attack code is released which target one very latest versions of WP site. In 1990, there is a software piracy scene that scene was called ‘warez’. The people illegally sharing modems using commercial software group. Scene still exists today, but uses BitTorrent and other more modern techniques. Back then, modems pirated software was slow and took a long time to move.

But in Modern, it is said that there is a security hole in the software industry, where the software vendor “zero days” to fix the problem was to indicate the warez scene of the 1990s the word ‘zero’ day is borrowed. So, for example if you have Adobe Flash in a “zero day” vulnerability, so that means that Adobe still has not been aware of the problem of security and there is a security hole that Adobe Flash millions of people are likely to be running version.

In cross-site scripting (XSS) bugs, attackers can easily inject code into the HTML content. However, both attacks by dropping malicious code into comments section which appear by default at the end of WordPress site, from here online criminals or attackers can change or add new administrator by altering the password or take as other legitimate admisn task. Mostly WordPress version 4.2 is vulnerable to such attacks, where there is no patch.

However, the loops that affects the WordPress 4.2 and its earlier, may be ruined by an unknown attackers or cyber criminals in order to execute arbitrary code via very large comments which can truncated while they are saving into database. Mainly vulnerabilities are occurs due to weak plugins, Themes and other WordPress add-ons. These are creating more security bugs through which attackers can easily take over your site and regain access your private or precious data or information. Before the fix was released, website owners running a self-hosted version of WordPress are advised to install the Askimet anti-spam plugin for protecting their WordPress site against potential unwanted or horrible attacks.

Today, security professionals often “Zero Day” as a 0day ‘Oh Day “has been declared, speaking in person to hear the pronunciation. So you have to look hip sure you want to make stick with correct pronunciation. “If a logged-in administrator is triggered, the default setting to take advantage of the vulnerability, the attacker through the plugin and theme editors can to execute arbitrary code on the server, Alternatively the attacker can change the administrator’s password, create a new administrator account, or whatever the currently logged-in administrator on the target system can be.”

Posting a comment some simple javascript code and then the text characters or about 66,000 more than the value of 64 kilobytes exploit works by adding a huge amount. Once the comment is processed by someone logged in with administrative rights to the site WordPress, no outward sign malicious code that will be executed with a running attack. By default, WordPress automatically post comments unless the user has already been approved by an administrator does not publish. Raiders by posting a benign comment that is approved can work around this limitation.

However, often, Zero Day vulnerabilities are not reported, the sites exploited four separate Zero day vulnerabilities and that is equivalent of digital weapons on Cyber War scenario. Since, it is very serious than known vulnerabilities. So, One can go through the protecting against Zero Day Vulnerabilities in order to save their WordPress site. And for that, you need to follow some method like as follows:

  • Signature based defense: This is a best technique which is designed on pattern matching to identify patterns in known vulnerabilities. However, This technique is not able to do a good protection of identifying specific code in Zero Day vulnerabilities, but it can easy to identify known attacks like SQL injection that target products suffering from a Zero Day vulnerability.
  • Statistical techniques: These know what normal actions displays like on a network. After that they will alert you if traffic or behavior disabled from that general profile.
  • Behavior based defense: There are various ways to implement this technique, but a common implementation relies on a ‘honeypot’.
  • Hybrid techniques: These are using a combination of statistical, behavior and traditional signature based algorithms. Therefore, they are more effective and they are able to avoid weaknesses in any single detection technique.
