Microsoft Patch Tuesday – July 9th 2024

Two ‘0-Days’ Being Actively Exploited in the Wild Are Among 49 Vulnerabilities This Month in Microsoft Windows


“Patch Tuesday” is an unofficial term used to refer to the second Tuesday of each month, when Microsoft, Adobe, Oracle, Google and other vendors regularly release software patches for their software products. Critical security updates are occasionally released outside of the normal Patch Tuesday cycle, but these are known as “Out-of-band” releases.

CVE-2024-38112: URI Spoofing Exploitation in MS Windows Trident Rendering Engine

A vulnerability exists in the MSHTML (Trident) rendering engine, which is pivotal for rendering web content in Internet Explorer. The primary flaw stems from inadequate sanitisation within the MSHTML library of URL links to malicious content originates from a trusted source. Attackers are exploiting the vulnerability to employ phishing tactics, sending emails with malicious attachments or links leading to spoofed websites. Upon interaction, malicious content is rendered in a trusted context, misleading users to divulge sensitive information like login credentials or to install malware.
