Cybersecurity researchers have shed light on a new sophisticated strain of malware that masquerades as a WordPress plugin to stealthily create administrator accounts and remotely control a compromised site. "Complete with a professional looking opening comment implying it is a caching plugin, this rogue code contains numerous functions, adds filters to prevent itself from being included in the list of activated plugins, and has pinging functionality that allows a malicious actor to check if the script is still operational, as well as file modification capabilities," Wordfence  said . The plugin also offers the ability to activate and deactivate arbitrary plugins on the site remotely as well as create rogue admin accounts with the username superadmin and a hard-coded password. In what's seen as an attempt to erase traces of compromise, it features a function named "_pln_cmd_hide" that's designed to remove the superadmin account when it's no longer req

A critical security flaw has been disclosed in miniOrange's  Social Login and Register plugin  for WordPress that could enable a malicious actor to log in as any user-provided information about email address is already known. Tracked as CVE-2023-2982 (CVSS score: 9.8), the authentication bypass flaw impacts all versions of the plugin, including and prior to 7.6.4. It was addressed on June 14, 2023, with the release of version 7.6.5 following responsible disclosure on June 2, 2023. "The vulnerability makes it possible for an unauthenticated attacker to gain access to any account on a site including accounts used to administer the site, if the attacker knows, or can find, the associated email address," Wordfence researcher István Márton  said . The issue is rooted in the fact that the encryption key used to secure the information during login using social media accounts is hard-coded, thus leading to a scenario where attackers could create a valid request with a properl

WordPress security company Wordfence on Thursday said it started detecting exploitation attempts targeting the newly disclosed flaw in Apache Commons Text on October 18, 2022. The vulnerability, tracked as  CVE-2022-42889  aka Text4Shell , has been assigned a severity ranking of 9.8 out of a possible 10.0 on the CVSS scale and affects versions 1.5 through 1.9 of the library. It's also similar to the now infamous  Log4Shell  vulnerability in that the  issue  is rooted in the manner  string substitutions  carried out during  DNS, script, and URL lookups  could lead to the execution of arbitrary code on susceptible systems when passing untrusted input. "The attacker can send a crafted payload remotely using 'script,' 'dns,' and 'url' lookups to achieve arbitrary remote code execution," the Zscaler ThreatLabZ team explained . A  successful exploitation of the flaw  can enable a threat actor to open a reverse shell connection with the vulnerable

A zero-day flaw in a WordPress plugin called  BackupBuddy  is being actively exploited, WordPress security company Wordfence has disclosed. "This vulnerability makes it possible for unauthenticated users to download arbitrary files from the affected site which can include sensitive information," it  said . BackupBuddy allows users to back up their entire WordPress installation from within the dashboard, including theme files, pages, posts, widgets, users, and media files, among others. The plugin is estimated to have around 140,000 active installations, with the flaw (CVE-2022-31474, CVSS score: 7.5) affecting versions 8.5.8.0 to 8.7.4.1. It's been addressed in version 8.7.5 released on September 2, 2022. The issue is rooted in the function called "Local Directory Copy" that's designed to store a local copy of the backups. According to Wordfence, the vulnerability is the result of an insecure implementation, which enables an unauthenticated threat acto

Researchers from Wordfence have  sounded  the alarm about a "sudden" spike in cyber attacks attempting to exploit an unpatched flaw in a WordPress plugin called  Kaswara Modern WPBakery Page Builder Addons . Tracked as  CVE-2021-24284 , the issue is rated 10.0 on the CVSS vulnerability scoring system and relates to an unauthenticated arbitrary file upload that could be abused to gain code execution, permitting attackers to seize control of affected WordPress sites. Although the bug was originally  disclosed  in April 2021 by the WordPress security company, it continues to remain unresolved to date. To make matters worse, the plugin has been closed and is no longer actively maintained. Wordfence, which is protecting over 1,000 websites that have the plugin installed, said it has blocked an average of 443,868 attack attempts per day since the start of the month. The attacks have emanated from 10,215 IP addresses, with a majority of the exploitation attempts narrowed down
