Apple fixed 39 vulnerabilities in its products

Apple has released fixes for 39 vulnerabilities in macOS Catalina, iOS, and iPadOS. The updates address memory safety flaws, some of which may lead to remote code execution.

In the fact sheet, Apple did not confirm exploitation of 0-day vulnerabilities in the wild. The company urged iPhone and iPad users to urgently upgrade to iOS 15.6 due to the risk of dangerous cyber attacks. 39 vulnerabilities have been fixed across a wide range of iOS/iPadOS components, including:

AppleAVD;

Millions of WordPress sites can be taken over by a single plugin

A massive campaign has been uncovered that scanned about 1.6 million WordPress sites for a vulnerable plugin that allows uploading files without authentication.

The attackers are targeting the Kaswara Modern WPBakery Page Builder plugin, which was abandoned by its author until the critical vulnerability CVE-2021-24284 was fixed. The vulnerability allows an unauthorized cybercriminal to inject malicious JavaScript code into websites using any version of the plugin, and download and delete files, which can lead to a complete takeover of the site.

1,599,852 unique websites were hacked, only a small part of them use the vulnerable plugin. The attacks have been ongoing since July 4, averaging 443,868 attack attempts each day. Attacks are carried out from 10,215 different IP addresses, with some of them generating millions of requests, while others are limited to fewer.

The attackers send a POST request to "wp-admin/admin-ajax/php" in an attempt to use the AJAX function of the "uploadFontIcon" plugin to upload a malicious payload containing a PHP file. This file invokes the NDSW Trojan, which injects code into JavaScript files present on the target sites in order to redirect visitors to phishing and malware sites.

Users should remove the Kaswara Modern WPBakery Page Builder Addons plugin from their WordPress sites. If the plugin is not used, users are still advised to block malicious IP addresses.
