New Flaw in WordPress Live Chat Plugin Lets Hackers Steal and Hijack Sessions

June 11, 2019Mohit Kumar
Security researchers have been warning about a critical vulnerability they discovered in one of a popular WordPress Live Chat plugin, which, if exploited, could allow unauthorized remote attackers to steal chat logs or manipulate chat sessions. The vulnerability, identified as CVE-2019-12498, resides in the "WP Live Chat Support" that is currently being used by over 50,000 businesses to provide customer support and chat with visitors through their websites. Discovered by cybersecurity researchers at Alert Logic , the flaw originates because of an improper validation check for authentication that apparently could allow unauthenticated users to access restricted REST API endpoints. As described by researchers, a potential remote attacker can exploit exposed endpoints for malicious purposes, including: stealing the entire chat history for all chat sessions, modifying or deleting the chat history, injecting messages into an active chat session, posing as a custome

If you own an eCommerce website built on WordPress and powered by WooCommerce plugin, then beware of a new, unpatched vulnerability that has been made public and could allow attackers to compromise your online store. A WordPress security company—called " Plugin Vulnerabilities "—that recently gone rogue in order to protest against moderators of the WordPress’s official support forum has once again dropped details  and proof-of-concept exploit for a critical flaw in a widely-used WordPress plugin. To be clear, the reported unpatched vulnerability doesn't reside in the WordPress core or WooCommerce plugin itself. Instead, the vulnerability exists in a plugin , called WooCommerce Checkout Manager , that extends the functionality of WooCommerce by allowing eCommerce sites to customize forms on their checkout pages and is currently being used by more than 60,000 websites. The vulnerability in question is an "arbitrary file upload" issue that can be exploi

Hackers Actively Exploiting Widely-Used Social Share Plugin for WordPress

April 23, 2019Swati Khandelwal
Hackers have been found exploiting a pair of critical security vulnerabilities in one of the popular social media sharing plugins to take control over WordPress websites that are still running a vulnerable version of the plugin. The vulnerable plugin in question is Social Warfare which is a popular and widely deployed WordPress plugin with more than 900,000 downloads. It is used to add social share buttons to a WordPress website or blog. Late last month, maintainers of Social Warfare for WordPress released an updated version 3.5.3 of their plugin to patch two security vulnerabilities—stored cross-site scripting (XSS) and remote code execution (RCE)—both tracked by a single identifier, i.e., CVE-2019-9978 . Hackers can exploit these vulnerabilities to run arbitrary PHP code and take complete control over websites and servers without authentication, and then use the compromised sites to perform digital coin mining or host malicious exploit code. However, the same day when Soc

WordPress iOS App Bug Leaked Secret Access Tokens to Third-Party Sites

April 03, 2019Swati Khandelwal
If you have a "private" blog with WordPress.com and are using its official iOS app to create or edit posts and pages, the secret authentication token for your admin account might have accidentally been leaked to third-party websites. WordPress has recently patched a severe vulnerability in its iOS application that apparently leaked secret authorization tokens for users whose blogs were using images hosted on third-party sites, a spokesperson for Automattic confirmed The Hacker News in an email. Discovered by the team of WordPress engineers, the vulnerability resided in the way WordPress iOS application was fetching images used by private blogs but hosted outside of WordPress.com, for example, Imgur or Flickr. That means, if an image were hosted on Imgur and then when the WordPress iOS app attempted to fetch the image, it would send along a WordPress.com authorization token to Imgur, leaving a copy of the token in the access logs of the Imgur's web server. It sh

New WordPress Flaw Lets Unauthenticated Remote Attackers Hack Sites

March 14, 2019Swati Khandelwal
If for some reason your WordPress-based website has not yet been automatically updated to the latest version 5.1.1, it's highly recommended to immediately upgrade it before hackers could take advantage of a newly disclosed vulnerability to hack your website. Simon Scannell, a researcher at RIPS Technologies GmbH, who previously reported multiple critical vulnerabilities in WordPress, has once again discovered a new flaw in the content management software (CMS) that could potentially lead to remote code execution attacks. The flaw stems from a cross-site request forgery (CSRF) issue in the Wordpress' comment section, one of its core components that comes enabled by default and affects all WordPress installations prior to version 5.1.1. Unlike most of the previous attacks documented against WordPress, this new exploit allows even an "unauthenticated, remote attacker" to compromise and gain remote code execution on the vulnerable WordPress websites.

Exclusive — If you have not updated your website to the latest WordPress version 5.0.3, it’s a brilliant idea to upgrade the content management software of your site now. From now, I mean immediately. Cybersecurity researchers at RIPS Technologies GmbH today shared their latest research with The Hacker News, revealing the existence of a critical remote code execution vulnerability that affects all previous versions of WordPress content management software released in the past 6 years. The remote code execution attack, discovered and reported to the WordPress security team late last year, can be exploited by a low privileged attacker with at least an "author" account using a combination of two separate vulnerabilities—Path Traversal and Local File Inclusion—that reside in the WordPress core.

Buying popular plugins with a large user-base and using it for effortless malicious campaigns have become a new trend for bad actors. One such incident happened recently when the renowned developer BestWebSoft sold a popular Captcha WordPress plugin to an undisclosed buyer, who then modified the plugin to download and install a hidden backdoor. In a blog post published on Tuesday, WordFence security firm revealed why WordPress recently kicked a popular Captcha plugin with more than 300,000 active installations out of its official plugin store. While reviewing the source code of the Captcha plugin, WordFence folks found a severe backdoor that could allow the plugin author or attackers to remotely gain administrative access to WordPress websites without requiring any authentication. The plugin was configured to automatically pull an updated "backdoored" version from a remote URL — https[://]simplywordpress[dot]net/captcha/captcha_pro_update.php — after installati

February 08, 2017Swati Khandelwal
Last week, we reported about a critical zero-day flaw in WordPress that was silently patched by the company before hackers have had their hands on the nasty bug to exploit millions of WordPress websites. To ensure the security of millions of websites and its users, WordPress delayed the vulnerability disclosure for over a week and worked closely with security companies and hosts to install the patch, ensuring that the issue was dealt with in short order before it became public. But even after the company's effort to protect its customers, thousands of admins did not bother to update their websites, which are still vulnerable to the critical bug and has already been exploited by hackers. While WordPress includes a default feature that automatically updates unpatched websites, some admins running critical services disable this feature for first testing and then applying patches. Even the news blog of one of the famous Linux distribution OpenSUSE (news.opensuse.org) was
