November 2025 CVE landscape: 10 exploited critical vulnerabilities, a 69% drop from October, and why Fortinet and Samsung flaws need urgent patching.
Analysis Summary
As a vulnerability research specialist, here is the summarized, actionable intelligence based on the November 2025 CVE landscape overview, focusing on the most critical and exploited flaws:
---
## Vulnerability: Fortinet FortiWeb Authentication Bypass (CVE-2025-64446)
## CVE Details
- CVE ID: CVE-2025-64446
- CVSS Score: 99 (Critical)
- CWE: CWE-23 (Relative Path Traversal)
## Affected Systems
- Products: Fortinet FortiWeb
- Versions: 8.0.0-8.0.1, 7.6.0-7.6.4, 7.4.0-7.4.9, 7.2.0-7.2.11, 7.0.0-7.0.11
- Configurations: Any exposed, internet-facing FortiWeb instance.
## Vulnerability Description
This is a critical unauthenticated path traversal vulnerability allowing remote attackers to bypass authentication entirely and subsequently create administrative accounts on the affected FortiWeb instances.
## Exploitation
- Status: Exploited in the wild (CISA KEV added November 14, 2025)
- Complexity: Low (Implied by unauthenticated nature and direct impact)
- Attack Vector: Network
## Impact
- Confidentiality: High (Ability to create admin accounts implies full system access)
- Integrity: High (Ability to create admin accounts implies full system access)
- Availability: High (Potential for service disruption or device takeover)
## Remediation
### Patches
- *Specific patch versions are not detailed in the summary, users must consult the vendor advisory for the fixed release.*
### Workarounds
- Restrict network access to FortiWeb management interfaces (e.g., via firewall rules) to only trusted IP addresses immediately.
## Detection
- **Indicators of Compromise (IOCs):** Logs indicating creation of new, unexpected administrative accounts.
- **Detection Methods and Tools:** Nuclei templates from Recorded Future's Insikt Group for non-intrusive path traversal detection are available to customers.

## Vulnerability: Samsung Image Processor Out-of-bounds Write (CVE-2025-21042)
## CVE Details
- CVE ID: CVE-2025-21042
- CVSS Score: 99 (Critical)
- CWE: CWE-787 (Out-of-bounds Write)
## Affected Systems
- Products: Samsung Mobile Devices (via image processing component)
- Versions: Not explicitly listed; affects devices processing media formats involved in the LANDFALL campaign.
- Configurations: Devices processing malicious DNG image files, potentially received via messaging applications like WhatsApp.
## Vulnerability Description
A critical Out-of-bounds Write vulnerability in Samsung's image processing component that allows for zero-click exploitation. Threat actors (LANDFALL campaign) are weaponizing malicious DNG image files delivered over messaging apps to achieve remote code execution.
## Exploitation
- Status: Exploited in the wild (LANDFALL spyware campaign targeting Middle East countries)
- Complexity: Low (Zero-click attack vector over messaging)
- Attack Vector: Network (via messaging application payload)
## Impact
- Confidentiality: High (Persistent device compromise)
- Integrity: High (Persistent device compromise)
- Availability: High (Persistent device compromise)
## Remediation
### Patches
- *Specific patch versions are not detailed in the summary, users must consult Samsung Mobile Security Advisories for the fix.*
### Workarounds
- Temporarily disable automatic media download/preview features in high-risk communication apps (e.g., WhatsApp) until the patch is applied.
- Harden SELinux policies if possible (though the described campaign achieved SELinux bypass).
## Detection
- **Indicators of Compromise (IOCs):** Detection of unusual system activity, execution patterns indicative of spyware, or indicators related to the LANDFALL campaign's anti-analysis techniques.
- **Detection Methods and Tools:** Attack Surface Intelligence tools to identify relevant, vulnerable mobile assets.

## Vulnerability: Microsoft Windows Kernel Race Condition (CVE-2025-62215)
## CVE Details
- CVE ID: CVE-2025-62215
- CVSS Score: 99 (Critical)
- CWE: CWE-362 (Race Condition), CWE-415 (Double Free)
## Affected Systems
- Products: Microsoft Windows 10 and 11; Microsoft Windows Server 2019, 2022, and 2025.
- Versions: All modern, unpatched versions of the listed operating systems.
- Configurations: Local access required for exploitation.
## Vulnerability Description
A kernel-level vulnerability involving a race condition vulnerability and a double free condition. Successful exploitation allows a local attacker with limited privileges to achieve SYSTEM-level privileges.
## Exploitation
- Status: Exploited in the wild (Public PoC available)
- Complexity: Medium (Requires local access and precise timing for the race condition)
- Attack Vector: Local
## Impact
- Confidentiality: High (SYSTEM privilege escalation)
- Integrity: High (SYSTEM privilege escalation)
- Availability: Low to Medium (Potential for crashes if exploitation fails)
## Remediation
### Patches
- *Specific patch versions are not detailed in the summary, users must consult the Microsoft Security Update Guide for the November release covering this CVE.*
### Workarounds
- Strictly enforce least-privilege principles; minimize or remove unnecessary local user accounts to limit potential attacker footholds.
## Detection
- **Indicators of Compromise (IOCs):** Unauthorized creation of services or abnormal modification of kernel memory structures.
- **Detection Methods and Tools:** Endpoint Detection and Response (EDR) systems monitoring for suspicious kernel API calls and memory manipulation patterns associated with privilege escalation.
