Unpacking the Vulnerabilities

This month’s updates unveil a variety of critical flaws, among them two classified as remote code execution vulnerabilities and two related to privilege elevation. Here’s a breakdown of the vulnerabilities: - **26 Elevation of Privilege Vulnerabilities** - **2 Security Feature Bypass Vulnerabilities** - **52 Remote Code Execution Vulnerabilities** - **1 Information Disclosure Vulnerability** - **4 Denial of Service Vulnerabilities** - **3 Spoofing Vulnerabilities** Notably, the tally provided does not encompass two Edge-specific vulnerabilities that were patched earlier on November 7.

Spotlight on Zero-Day Vulnerabilities

A zero-day flaw, defined as a vulnerability publicly exposed or exploited without an existing fix, is a potent threat in cybersecurity. This month's Patch Tuesday addresses four such zero-days, with two actively exploited. 1. **CVE-2024-43451 - NTLM Hash Disclosure Spoofing Vulnerability** - Discovered by Israel Yeshurun from ClearSky Cyber Security, this vulnerability can leak NTLM hashes to malicious remote attackers through minimal user interaction with a malicious file. Potentially, an attacker could impersonate the affected user with the stolen hash. 2. **CVE-2024-49039 - Windows Task Scheduler Elevation of Privilege Vulnerability** - This vulnerability allows attackers to elevate privileges through specially crafted applications. It was identified by researchers Vlad Stolyarov and Bahare Sabouri from Google's Threat Analysis Group, enabling attackers to execute tasks typically restricted to privileged accounts. The remaining three zero-day vulnerabilities, while publicly disclosed, have not been exploited in attacks: 3. **CVE-2024-49040 - Microsoft Exchange Server Spoofing Vulnerability** - Risking email authenticity, this flaw found in Microsoft Exchange Server permits attackers to spoof sender addresses, potentially misleading recipients. Microsoft has instituted a warning in emails deemed suspicious, urging users to verify sources. 4. **CVE-2024-49019 - Active Directory Certificate Services Elevation of Privilege Vulnerability** - This security concern relates to built-in version 1 certificate templates that attackers can manipulate to gain domain admin privileges. Insights from experts at TrustedSec highlight potential risks stemming from broader permissions granted during certificate enrollment.

Additional Updates from Other Tech Giants

Beyond Microsoft’s updates, other tech firms are also busy patching vulnerabilities in their systems. Notable releases in November 2024 include: - **Adobe** has issued updates for a range of applications, including Photoshop and Illustrator. - **Cisco** has addressed vulnerabilities across products like Cisco Phones and Nexus Dashboard. - Reports from **Citrix**, **Dell**, **D-Link**, **Google**, and others reveal ongoing efforts to safeguard against these vulnerabilities with updates across various platforms and services.
