Critical Unpatched Flaw Disclosed in WordPress WooCommerce Extension

April 26, 2019Swati Khandelwal
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
New PHP Code Execution Attack Puts WordPress Sites at Risk

New PHP Code Execution Attack Puts WordPress Sites at Risk

August 17, 2018Wang Wei
Sam Thomas, a security researcher from Secarma, has discovered a new exploitation technique that could make it easier for hackers to trigger critical deserialization vulnerabilities in PHP programming language using previously low-risk considered functions. The new technique leaves hundreds of thousands of web applications open to remote code execution attacks, including websites powered by some popular content management systems like WordPress and Typo3. PHP unserialization or object injection vulnerabilities were initially documented in 2009, which could allow an attacker to perform different kinds of attacks by supplying malicious inputs to the unserialize() PHP function. If you are unaware, serialization is the process of converting data objects into a plain string, and unserialize function help program recreate an object back from a string. Thomas found that an attacker can use low-risk functions against Phar archives to trigger deserialization attack without requiring

Nearly 2000 WordPress Websites Infected with a Keylogger

January 29, 2018Swati Khandelwal
More than 2,000 WordPress websites have once again been found infected with a piece of crypto-mining malware that not only steals the resources of visitors' computers to mine digital currencies but also logs visitors' every keystroke. Security researchers at Sucuri discovered a malicious campaign that infects WordPress websites with a malicious script that delivers an in-browser cryptocurrency miner from CoinHive and a keylogger. Coinhive is a popular browser-based service that offers website owners to embed a JavaScript to utilise CPUs power of their website visitors in an effort to mine the Monero cryptocurrency. Sucuri researchers said the threat actors behind this new campaign is the same one who infected more than 5,400 Wordpress websites last month since both campaigns used keylogger/cryptocurrency malware called cloudflare[.]solutions. Spotted in April last year, Cloudflare[.]solutions is cryptocurrency mining malware and is not at all related to network

GHOST glibc Vulnerability Affects WordPress and PHP applications

January 30, 2015Swati Khandelwal
After the disclosure of extremely critical GHOST vulnerability in the GNU C library (glibc) — a widely used component of most Linux distributions, security researchers have discovered that PHP applications, including the WordPress Content Management System (CMS), could also be affected by the bug.
