Fortinet FortiClient Enterprise Management Server (EMS) CVE-2026-35616

-




Fortinet Enterprise Management Server CVE-2026-35616 is a critical security vulnerability affecting

 Key Facts

  • Severity: Critical (CVSS ~9.1–9.8)
  • Type: Improper access control (CWE-284)
  • Affected versions: FortiClient EMS 7.4.5 and 7.4.6
  • Exploitation: Actively exploited in the wild (including zero‑day activity)
  • Attack vector: Remote, no authentication required

 What the Vulnerability Does

This flaw allows an attacker to:
  • Bypass API authentication
  • Send crafted requests directly to the EMS server
  • Execute arbitrary commands or code remotely
 In short: unauthenticated remote code execution (RCE).
Because EMS centrally manages endpoints, exploitation can give attackers:
  • Administrator-level control of EMS
  • Ability to push malicious scripts to all managed endpoints

 Real-World Exploitation

Attackers have already used CVE-2026-35616 to:
  • Deliver credential-stealing malware (EKZ infostealer)
  • Push malicious PowerShell scripts via legitimate EMS management channels
  • Harvest sensitive data like:
    • Browser passwords
    • Cookies
    • Credit card and autofill info
This makes the vulnerability especially dangerous because:
  • It leverages trusted infrastructure
  • It can pivot to every managed endpoint quickly

 Root Cause

  • The EMS API fails to properly validate authentication
  • Requests can be processed as if they were from an admin user

 Fix / Mitigation

Immediate action required:
  1.  Upgrade to:
    • FortiClient EMS 7.4.7 or later
  2.  Apply hotfixes if stuck on:
    • 7.4.5 / 7.4.6
  3.  Additional defensive steps:
    • Restrict EMS access (do not expose to Internet)
    • Monitor for:
      • Suspicious API calls
      • Unusual script execution via EMS
    • Hunt for indicators like:
      • fortitray.exe → cmd → powershell chains

 Why It Matters

  • Listed in CISA Known Exploited Vulnerabilities (KEV) catalog
  • Zero authentication + full control = high enterprise risk
  • Centralized management tool compromise = network-wide breach potential

 Bottom Line

CVE-2026-35616 is a high-impact, actively exploited RCE vulnerability in FortiClient EMS that can give attackers full administrative control and mass endpoint access. Patch immediately and assume compromise if exposed.
If you want, I can help you:

  • Detect exploitation (SIEM queries / logs)
  • Validate if your EMS is exposed
  • Build a quick incident response checklist for this CVE

WSUS CVE-2025-59287 Mitigation

-
Image
CVE-2025-59287 is a critical Remote Code Execution (RCE) vulnerability affecting Windows Server Update Services (WSUS) . Here's a detailed breakdown of what it is, how it works, and what you should do about it: Overview Disclosed: October 2025 Patch Tuesday CVSS Score: 9.8 (Critical) Affected Systems: Windows Server 2012 through 2025 (including Server Core installations) Exploitability: Microsoft rates it as “Exploitation More Likely” Technical Details The vulnerability arises from unsafe deserialization of untrusted data in WSUS. Specifically, the GetCookie() endpoint in WSUS processes encrypted AuthorizationCookie objects without proper type validation. The deserialization occurs via .NET BinaryFormatter , which is known to be insecure when handling untrusted input. Attackers can send a crafted SOAP request to WSUS over port 8530 , containing a malicious AuthorizationCookie . The cookie is decrypted using a hardcoded AES key and then deserialized, allow...

Cloud Infrastructures are Having a Bad Week

-
Image
  Today’s disruptions across Microsoft Azure and Amazon Web Services (AWS) were significant, but they’re not signs of cloud computing’s demise. Instead, they underscore the risks of centralization and the importance of designing systems that can withstand provider-level failures. What happened today? • Microsoft Azure outage: Azure’s Front Door service suffered a major disruption due to a misconfiguration, impacting services like Outlook, Xbox, Microsoft 365, and even third-party platforms like Starbucks and Alaska Airlines. The Azure website states a little more than disruption. "Azure Front Door - Connectivity issues - Observing recovery Starting at approximately 16:00 UTC on 29 October 2025, customers and Microsoft services leveraging Azure Front Door (AFD) may have experienced latencies, timeouts, and errors. We have confirmed that an inadvertent configuration change was the trigger event for this issue. Affected Azure services may have included, but were not limited to: App S...

Broadcom is dismantling of VMware Cloud Service Providers (VCSPs)

-
Image
  What Broadcom Is Doing to the VCSP Program 1. Broadcom is shutting down the existing VCSP program Multiple sources confirm that Broadcom issued formal non‑renewal notices to many VMware Cloud Service Providers, ending contracts as of January 26, 2026 . Partners may finish existing commitments but cannot renew or create new long‑term contract commitments . 2. Moving to an invite‑only VCSP ecosystem Broadcom is replacing the open VCSP model with a highly selective, invite‑only program , keeping only a small fraction of providers . For example: • Only 19 providers in the U.S. were retained out of thousands. • Hundreds of European providers are being cut loose. 3. White Label program sunset (critical for smaller providers) The White Label model—previously the path for smaller CSPs—has been terminated (or will be phased out depending on region). This effectively eliminates market access for many small providers. 4. Providers that are cut must hand off customers Broadcom directs ...

FBI Seizes RAMP Cybercrime Forum

-
Image
The FBI has taken down RAMP (Russian Anonymous Marketplace) , one of the most active cybercrime forums used by ransomware gangs, initial access brokers, malware sellers, and extortion groups . The takedown affected both the clearnet and dark‑web (Tor) domains, which now display official FBI/DOJ seizure notices. Why RAMP Was Significant RAMP was: Known as “the only place ransomware allowed.” A major hub for groups including LockBit, ALPHV/BlackCat, Conti, DragonForce, Qilin, RansomHub , and more. A high‑trust marketplace offering malware, exploits, tutorials, and escrow services . Home to 14,000+ vetted users , some paying fees for anonymity. Impact of the Seizure 1. Major Disruption to Criminal Infrastructure The takedown is seen as a meaningful blow against ransomware‑as‑a‑service communities. 2. Forced Migration to Other Forums Criminal groups are already shifting activity to alternative platforms like Rehub . These migrations are chaotic and risky for criminals due to: Loss of rep...

Notepad++ update service was compromised

-
Image
  Notepad++ update service was compromised Multiple independent security investigations confirm that Notepad++’s update infrastructure was hijacked between June and December 2025 . This was a supply-chain attack originating from a compromise at the hosting‑provider level , not from Notepad++’s code. What exactly was compromised? 1. Update traffic was intercepted and redirected Attackers manipulated the update endpoint ( getDownloadUrl.php ) so that some users requesting updates were silently redirected to malicious servers serving tampered executables . 2. It was targeted , not widespread All sources emphasize that only specific users were affected, likely in an espionage‑focused campaign , not a mass malware distribution effort. 3. Hosting provider compromise, not a Notepad++ bug The attackers gained access to the shared hosting environment , losing direct access in September 2025 but maintaining stolen internal service credentials through December 2, 2025.
