📊 EXECUTIVE SUMMARY

The last 24 hours saw three new entries added to CISA’s Known Exploited
Vulnerabilities (KEV) catalog. Attackers are actively exploiting
a critical out‑of‑bounds write in WatchGuard Firebox VPN, an improper
access control flaw in Gladinet Triofox, and a Windows kernel race
condition enabling privilege escalation. Operation Endgame dominated
incident reporting, with law enforcement dismantling more than 1,000
infostealer servers. Threat actor activity includes exploitation of
zero‑day pre‑authentication RCEs in Cisco ISE and Citrix NetScaler,
and the resurgence of Danabot, Fantasy Hub and GlassWorm malware.

Today’s Threat Landscape:

• 🚨 Actively Exploited: 3 vulnerabilities added to CISA KEV
(WatchGuard Firebox CVE‑2025‑9242, Gladinet Triofox CVE‑2025‑12480, and
Windows Kernel CVE‑2025‑62215cyberpress.org).
• 💥 Major Incidents: Operation Endgame took down 1,025 infostealer
servers and 20 domainsdatabreaches.net.
• 🎯 Detection Ready: 4 proof‑of‑concepts with Sigma rules.
• ⚠️ Watch Closely: 4 high‑severity CVEs (Windows GDI+ RCE,
Windows WSLg GUI RCE, Kerberos privilege escalation, Kibana SSRF).

Immediate Actions Required:

  1. Patch WatchGuard Firebox, Triofox and Windows systems (see Part 1).

  2. Deploy detection rules for IKEv2 exploitation, Host header abuse,
    kernel privilege escalation and remote management misuse.

  3. Audit admin accounts and antivirus settings on Triofox servers; hunt
    for IOCs related to Operation Endgame and PatoRAT.

PART 1: THREAT INTELLIGENCE BRIEF

🚨 Actively Exploited Vulnerabilities

1️⃣ WatchGuard Firebox IKEv2 Out‑of‑Bounds Write

CVE ID: CVE‑2025‑9242
Product: WatchGuard Firebox/Fireware OS versions 11.10.2 through
11.10.10, 11.12.x, and 12.0–12.10 (resolves in 12.10.1 U3)securityaffairs.com.
CVSS: 9.3 — Critical
Status: 🔴 ACTIVE EXPLOITATION (CISA KEV)cyberpress.org

What’s Happening:
An out‑of‑bounds write in the Fireware IKEv2 service allows
unauthenticated remote attackers to execute arbitrary code via crafted
IKE packets. WatchGuard and CISA reported active exploitation; the bug
can be triggered via the mobile‑user or branch‑office VPN, enabling
attackers to drop and run payloads on the firewallsecurityaffairs.com.

Affected Versions: Fireware OS 11.10.2 → 12.10.0; resolved in
12.10.1 U3securityaffairs.com.

Your Action Plan:
✅ Patch by: 3 Dec 2025 (CISA deadline)cyberpress.org
✅ Hunt for IKEv2 IOCs: unusual UDP 500 traffic, repeated SA Init
messages, and unapproved VPN user accounts.
✅ Deploy detection: See Sigma rule in Part 2 (PoC #1).

2️⃣ Gladinet Triofox Improper Access Control

CVE ID: CVE‑2025‑12480
Product: Gladinet Triofox / CentreStack cloud file sharing platform
CVSS: 8.8 — High
Status: 🔴 ACTIVE EXPLOITATION (CISA KEV)cyberpress.org

What’s Happening:
Mandiant observed threat group UNC6485 bypassing the Triofox admin
interface by setting the HTTP Host header to localhost, which allowed
unauthenticated access to the setup page. The attackers created a
Cluster Admin account and leveraged the built‑in antivirus feature to
upload and execute scripts like centre_report.bat that downloaded
legitimate tools such as Zoho Unified Endpoint Management Server and
remote access softwaresocprime.com. They pivoted via SSH
tunnels and enumerated domain accountssocprime.com.

Affected Versions: Triofox 6.2 (U1) and earlier; fixed in 6.3.0.

Your Action Plan:
✅ Patch by: 3 Dec 2025cyberpress.org
✅ Audit admin accounts; delete unauthorized Cluster Admin users.
✅ Verify antivirus paths and monitor for unusual file uploads or
outbound SSH connectionssocprime.com.
✅ Deploy detection: See Sigma rule in Part 2 (PoC #2).

→ CISA KEV and vendor advisory

3️⃣ Windows Kernel Race Condition Privilege Escalation

CVE ID: CVE‑2025‑62215
Product: Microsoft Windows 10/11, Server 2016–2025
CVSS: 7.0 — High
Status: 🔴 ACTIVE EXPLOITATION (CISA KEV)cyberpress.org

What’s Happening:
A race condition in the Windows kernel’s memory manager can lead to a
double‑free, corrupting heap structures and allowing an attacker with
local access to elevate privileges. Exploitation requires running
multiple threads to trigger the race, and no public PoC is available at
the time of writingcyberpress.org. Security researchers
emphasize that this vulnerability is likely used post‑exploitation to
gain SYSTEM privileges and has been exploited in the wildinfosecurity-magazine.com.

Affected Versions: All supported Windows releases prior to the
November 2025 Patch Tuesday cumulative updatescyberpress.org.

Your Action Plan:
✅ Apply November 2025 security updates immediately.
✅ Harden systems against initial compromise; monitor for unusual
privilege escalation patterns.
✅ Deploy detection: See Sigma rule in Part 2 (PoC #3).

PoC #1: WatchGuard Firebox IKEv2 RCE

CVE: CVE‑2025‑9242 | Product: WatchGuard Firebox / Fireware OS
CVSS: 9.3 | KEV Status: 🔴 Active

Exploit Summary:
The watchTowr team released a Python script that sends a crafted IKEv2
Security Association (SA) Init message and leverages a ROP chain to
trigger an out‑of‑bounds write in the IKEv2 service, resulting in
unauthenticated remote code execution on the firewallraw.githubusercontent.com.
The script prints [#] IKEv2 service is vulnerable when successful and
provides options to build an exploit payloadraw.githubusercontent.com.

Attack Chain:

  1. Send IKEv2 SA Init with manipulated payload length.

  2. Overwrite return address and inject ROP chain.

  3. Execute arbitrary code on the firewall.

✅ PART 2 ACTION ITEMS

🚀 DEPLOY NOW:

  1. Import Sigma rules watchguard_ikev2_oobwrite,
    triofox_host_header_bypass, triofox_anomalous_upload,
    windows_kernel_race_condition, windows_privilege_escalation,
    rmm_tool_abuse, and rmm_companyid_c2 into SIEM.

  2. Enable high‑severity alerting for IKEv2 and Triofox detections.

  3. Run 30‑day hunt queries for each PoC across all log sources.

🔧 THIS WEEK:
4. [ ] Validate rules with synthetic exploit traffic and tune false
positives (especially Windows kernel detection).
5. [ ] Add file hashes and domains to your threat intel platform and
block lists.
6. [ ] Assess coverage of remote management tools within your EDR and
implement allowlists.
7. [ ] Document triage procedures for each detection scenario.

📊 CONTINUOUS:
8. [ ] Monitor alert volume and adjust threshold values for network
detections.
9. [ ] Enrich alerts with asset context (critical servers vs. user
endpoints).
10. [ ] Review Sigma rules weekly for updates from the community.

🎯 COMBINED ACTION PLAN

PRIORITY 1 (Next 4 Hours):

☑️ Review all actively exploited vulnerabilities and confirm your
environment’s exposure.
☑️ Deploy Sigma rules for IKEv2, Triofox and RMM abuse.
☑️ Run quick hunts for Host: localhost and CompanyId anomalies.
☑️ Notify asset owners of patch requirements.

PRIORITY 2 (Next 24 Hours):

☑️ Apply patches (Fireware OS, Triofox, Windows, Cisco ISE) and
audit admin accounts.
☑️ Execute 30‑day hunt queries across logs; follow up on any
potential intrusion indicators.
☑️ Validate detection coverage using simulation frameworks (e.g.,
Atomic Red Team).
☑️ Review false positives and tune detection logic.

PRIORITY 3 (This Week):

☑️ Conduct a tabletop exercise to simulate exploitation of CVE‑2025‑9242
and CVE‑2025‑12480; refine incident response.
☑️ Update detection backlog to include PoCs for high‑severity CVEs in
the watchlist (GDI+ RCE, WSLg RCE, Kerberos)darkreading.com.
☑️ Perform an ATT&CK coverage assessment; map new detections to
identified tactics and techniques.
☑️ Strengthen vulnerability management workflows with patch gap
metrics.
