To make matters worse, attackers could leverage outdated or abandoned plugins to circumvent security measures, tamper with database records, execute malicious scripts, and seize control of the sites. WPScan said it uncovered the security defect when analyzing an infection on an unspecified WordPress site, finding that threat actors ...

Two critical security flaws impacting the Spam protection, Anti-Spam, and FireWall plugin for WordPress could allow an unauthenticated attacker to install and enable malicious plugins on susceptible sites and potentially achieve remote code execution. The vulnerabilities, tracked as CVE-2024-10542 and CVE-2024-10781 , carry a CVSS score of 9.8 out of a maximum of 10.0. They were addressed in versions 6.44 and 6.45 released this month. Installed on over 200,000 WordPress sites, CleanTalk's Spam protection,f Anti-Spam, FireWall plugin is advertised as a "universal anti-spam plugin" that blocks spam comments, registrations, surveys, and more. According to Wordfence, both vulnerabilities concern an authorization bypass issue that could allow a malicious actor to install and activate arbitrary plugins. This could then pave the way for remote code execution if the activated plugin is vulnerable of its own. The plugin is "vulnerable to unauthorized Arbitrary Plugin ...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

That said, it's worth poi...

WordPress.org has announced a new account security measure that will require accounts with capabilities to update plugins and themes to activate two-factor authentication (2FA) mandatorily. The enforcement is expected to come into effect starting October 1, 2024. "Accounts with commit access can push updates and changes to plugins and themes used by millions of WordPress sites worldwide," the maintainers of the open-source, self-hosted version of the content management system (CMS) said . "Securing these accounts is essential to preventing unauthorized access and maintaining the security and trust of the WordPress.org community."

Multiple WordPress plugins have been backdoored to inject malicious code that makes it possible to create rogue administrator accounts with the aim of performing arbitrary actions. "The injected malware attempts to create a new administrative user account and then sends those details back to the attacker-controlled server," Wordfence security researcher Chloe Chamberland said in a Monday alert. "In addition, it appears the threat actor also injected malicious JavaScript into the footer of websites that appears to add SEO spam throughout the website." The admin accounts have the usernames "Options" and "PluginAuth," with the account information exfiltrated to the IP address 94.156.79[.]8. It's currently not known how the unknown attackers behind the campaign managed to compromise the plugins, but the earliest signs of the software supply chain attack date back to June 21, 2024. The plugins in question are no longer available for downlo...

It's worth noting that the issue only affects users who have checked the "Enable custom table for usermeta" option in the plugin settings. ...

Threat hunters have discovered a rogue WordPress plugin that's capable of creating bogus administrator users and injecting malicious JavaScript code to steal credit card information. The skimming activity is part of a  Magecart campaign  targeting e-commerce websites, according to Sucuri. "As with many other malicious or fake WordPress plugins it contains some deceptive information at the top of the file to give it a veneer of legitimacy," security researcher Ben Martin  said . "In this case, comments claim the code to be 'WordPress Cache Addons.'" Malicious plugins typically find their way to WordPress sites via either a  compromised admin user  or the  exploitation of security flaws  in another plugin already installed on the site. Post installation, the plugin replicates itself to the  mu-plugins  (or must-use plugins) directory so that it's automatically enabled and conceals its presence from the admin panel. "Since the only way to...

As many as 47,337 malicious plugins have been uncovered on 24,931 unique websites, out of which 3,685 plugins were sold on legitimate marketplaces, netting the attackers $41,500 in illegal revenues. The findings come from a new tool called  YODA  that aims to detect rogue WordPress plugins and track down their origin, according to an 8-year-long study conducted by a group of researchers from the Georgia Institute of Technology. "Attackers impersonated benign plugin authors and spread malware by distributing pirated plugins," the researchers  said  in a new paper titled " Mistrust Plugins You Must ." "The number of malicious plugins on websites has steadily increased over the years, and malicious activity peaked in March 2020. Shockingly, 94% of the malicious plugins installed over those 8 years are still active today." The large-scale research entailed analyzing WordPress plugins installed in 410,122 unique web servers dating all the way back to 2012...
