In addition to the actively exploited vulnerabilities, several other critical flaws were also addressed: 

  • CVE-2025-21376: A Windows Lightweight Directory Access Protocol (LDAP) RCE vulnerability that could allow attackers to execute arbitrary code remotely. 
  • CVE-2025-21379: A DHCP Client Service RCE vulnerability that may enable remote attackers to execute code with elevated privileges. 
  • CVE-2025-21381: An RCE vulnerability in Microsoft Excel that could be triggered through malicious spreadsheet files. 

Remediation: 

  • Apply Updates: Immediately install the February 2025 Patch Tuesday updates to address these vulnerabilities. 

Conclusion: 

The February 2025 Patch Tuesday release addresses critical security vulnerabilities, including actively exploited zero-days. Timely application of these updates is essential to protect systems from potential threats. Organizations should review the affected products and implement the necessary patches and mitigations to maintain security integrity. 

The attack vector is local, meaning the attacker needs local access — physically or remotely, using SSH method without user interaction and if successful in exploiting, can give the attacker system privileges.

Apple’s USB Restricted Mode Exploited in Targeted Attacks 

OEM Apple 
Severity High 
CVSS Not Assigned 
CVEs CVE-2025-24200   
Exploited in Wild No 
Patch/Remediation Available Yes 
Advisory Version 1.0 

Overview 

Apple has issued emergency security patches to mitigate a zero-day vulnerability, CVE-2025-24200, which has been actively exploited in sophisticated attacks targeting specific individuals. The flaw allows attackers to bypass USB Restricted Mode on a locked device, potentially exposing sensitive data. Initially identified by The Citizen Lab, this vulnerability is believed to have been leveraged in real-world scenarios against high-profile targets. Apple has responded by enhancing state management in iOS 18.3.1 and iPadOS 18.3.1 to prevent exploitation. 

Vulnerability Name CVE ID Product Affected Severity 
 USB Restricted Mode Bypass Vulnerability  CVE-2025-24200  Apple  High 

Technical Summary 

The vulnerability, tracked as CVE-2025-24200, affects USB Restricted Mode, a security feature introduced in 2018 to prevent data transfer over USB when a device remains locked for seven days. A flaw in the Accessibility framework allows an attacker with physical access to disable USB Restricted Mode, bypassing this protection and potentially accessing sensitive data. 

Apple has mentioned “This issue has been exploited in extremely sophisticated attacks against specific individuals.” The vulnerability was discovered by Bill Marczak, a senior researcher at The Citizen Lab. 

CVE ID System Affected Vulnerability Details Impact 
CVE-2025-24200 iPhone XS and later iPad Pro (13-inch) iPad Pro 12.9-inch (3rd generation and later) iPad Pro 11-inch (1st generation and later) iPad Air (3rd generation and later) iPad (7th generation and later) iPad mini (5th generation and later) A flaw in the Accessibility framework allows a physical attacker to disable USB Restricted Mode, bypassing protections designed to prevent unauthorized data transfer.   Unauthorized access to sensitive data 

Remediation: 

  1. Users are strongly advised to update their devices to the latest versions: 
  • iOS: Update to version 18.3.1 
  • iPadOS: Update to version 18.3.1 
  1. To update your device, go to Settings > General > Software Update, and follow the on-screen instructions. 

Conclusion 

The CVE-2025-24200 vulnerability poses a serious risk to device security, particularly for individuals targeted in sophisticated cyberattacks. While the exploitation has been limited to specific individuals, all users of affected devices should install the latest updates immediately to mitigate potential risks. Apple remains committed to user security by addressing vulnerabilities promptly and ensuring continuous protection against emerging threats.

Active Exploitation of Microsoft Outlook RCE Vulnerability (CVE-2024-21413) 

A critical remote code execution (RCE) vulnerability, CVE-2024-21413, affecting Microsoft Outlook has been actively exploited.

CISA has directed U.S. federal agencies to secure their systems against ongoing cyberattacks targeting this vulnerability, tracked as CVE-2024–21413. The flaw was originally discovered by Check Point vulnerability researcher Haifei Li and is a result of improper input validation when processing emails containing malicious links.

OEM Microsoft 
Severity Critical 
CVSS 9.8 
CVEs CVE-2024-21413 
Exploited in Wild Yes 
Patch/Remediation Available Yes 
Advisory Version 1.0 

Overview 

The flaw allows attackers to bypass security protections, leading to NTLM credential theft and arbitrary code execution. The vulnerability is critical, and Microsoft has released patches to mitigate the risk. 

Vulnerability Name CVE ID Product Affected Severity 
 Remote Code Execution Vulnerability  CVE-2024-21413  Microsoft  Critical 

Technical Summary 

The CVE-2024-21413 vulnerability arises due to improper input validation in Microsoft Outlook when handling emails containing malicious links. Exploitation of this flaw enables attackers to bypass Protected View, a security feature designed to prevent execution of harmful content embedded in Office files. 

By manipulating URLs with the file:// protocol and inserting an exclamation mark followed by arbitrary text, attackers can evade Outlook’s built-in security measures, tricking users into opening malicious Office files in editing mode instead of read-only mode. The Preview Pane also serves as an attack vector, enabling zero-click exploitation. Here is the POC also available for this vulnerabilty. 

CVE ID System Affected Vulnerability Details Impact 
CVE-2024-21413 Microsoft Office LTSC 2021, Microsoft 365 Apps, 
Microsoft Outlook 2016, Microsoft Office 2019   		Exploits improper input validation to bypass Outlook security protections using manipulated hyperlinks.  NTLM credential theft, remote code execution, potential full system compromise  

Remediation: 

  1. Apply Security Patches: Ensure that all the Microsoft Office products are updated with the latest security patches. 
  1. Disable NTLM Authentication: Where feasible, reduce reliance on NTLM authentication to prevent credential theft. 

General Remediation: 

  1. Monitor Network Activity: Watch unusual outbound connections to attacker-controlled servers. 
  1. User Awareness Training: Educate employees on recognizing phishing attempts and avoiding click on suspicious links or attachments. 
  1. Enable Advanced Threat Protection: Use security tools like Microsoft Defender to enhance security monitoring and detection. 
  1. Regularly Update Software: Maintain a routine patching schedule to ensure all systems are protected against known vulnerabilities. 
  1. Restrict Macros and External Content: Configure Microsoft Office to block macros and disable automatic external content execution. 

Conclusion: 

The exploitation of CVE-2024-21413 underscores the ongoing threat posed by improperly validated inputs in widely used enterprise software. With this vulnerability being actively exploited and the POC publicly available, organizations must prioritize patching, strengthen monitoring, and follow best security practices to minimize risks. CISA has included CVE-2024-21413 in its Known Exploited Vulnerabilities (KEV) catalog, emphasizing the need for immediate action.
