CISA Adds Critical WatchGuard Fireware Flaw to KEV

🔒 CISA has added a critical WatchGuard Fireware vulnerability, CVE-2025-9242 (CVSS 9.3), to its Known Exploited Vulnerabilities catalog after evidence of active exploitation. The out-of-bounds write in the OS iked process affects Fireware OS 11.10.2 through 11.12.4_Update1, 12.0 through 12.11.3 and 2025.1 and can allow remote unauthenticated code execution. Researchers at watchTowr Labs attribute the flaw to a missing length check on an identification buffer used during the IKE handshake, which permits a pre‑authentication code path before certificate validation. Shadowserver scans show over 54,300 vulnerable Firebox instances worldwide (about 18,500 in the U.S.), and Federal Civilian Executive Branch agencies are directed to apply WatchGuard patches by December 3, 2025.

Canon TTF Printer Vulnerability Allows Remote Code Execution

🖨️ Independent researcher Peter Geissler disclosed a critical vulnerability (CVE-2024-12649) in certain Canon printers that can be triggered simply by printing an XPS document containing a malicious TTF font. The exploit abuses TTF hinting instructions to overflow a virtual-machine stack in the printer’s font engine, allowing code execution on devices running Canon’s DryOS. Canon has issued firmware updates, but organizations should promptly patch, restrict printer exposure, and segment printers to reduce risk.

Microsoft fixes false Windows 10 end-of-support alerts

🔧 Microsoft resolved a bug that caused incorrect end-of-support warnings to appear in Windows Update settings after the October 2025 updates. The cosmetic issue affected Windows 10 22H2 devices enrolled in the Extended Security Updates (ESU) program as well as LTSC 2021 editions that remain supported, but affected systems continued to receive security updates. Microsoft issued a cloud configuration fix and on Nov 11, 2025 released KB5068781; admins can also apply a Known Issue Rollback policy if immediate deployment is required.

CISA Issues Guidance for Cisco ASA and Firepower Fixes

🔔 CISA released implementation guidance for Cisco ASA and Firepower devices to support Emergency Directive 25-03. The guidance lists minimum software versions that remediate CVE-2025-20333 and CVE-2025-20362 and directs agencies to perform corrective patching. CISA warns multiple organizations believed they had applied updates but had not and recommends all operators verify exact versions. Agencies with devices not yet updated or updated after Sept. 26, 2025, should follow additional temporary mitigations.

Active Directory Under Siege: Risks in Hybrid Environments

🔐 Active Directory remains the critical authentication backbone for most enterprises, and its growing complexity across on‑premises and cloud hybrids has expanded attackers' opportunities. The article highlights common AD techniques — Golden Ticket, DCSync, and Kerberoasting — and frequent vulnerabilities such as weak and reused passwords, lingering service accounts, and poor visibility. It recommends layered defenses: strong password hygiene, privileged access management, zero‑trust conditional access, continuous monitoring, and rapid patching. The piece stresses that AD security is continuous and highlights solutions that block compromised credentials in real time.

Microsoft fixes Windows Task Manager bug hurting performance

⚠️ Microsoft released a fix for a Windows 11 Task Manager issue introduced by the optional preview update KB5067036 that could leave multiple taskmgr.exe processes running after the window was closed. The defect, blamed for stuttering and CPU hangs on affected systems, is resolved in the November cumulative security update KB5068861. Microsoft recommends installing KB5068861, and users who cannot immediately update can temporarily terminate lingering Task Manager processes by running an elevated Command Prompt and executing taskkill.exe /im taskmgr.exe /f.

Microsoft Patches 63 Flaws Including Kernel Zero‑Day

🔒 Microsoft released patches for 63 vulnerabilities, four rated Critical and 59 Important, including a Windows Kernel zero-day (CVE-2025-62215) that Microsoft says is being exploited in the wild. The flaws span privilege escalation, remote code execution, information disclosure and DoS, with notable heap-overflow issues in Graphics Component and WSL GUI. Administrators are urged to prioritize updates where exploits are known or where vulnerabilities permit privilege escalation or remote code execution.

Microsoft Fixes Windows Kernel Zero Day in November

🔒 Microsoft released its November Patch Tuesday updates addressing over 60 CVEs, including an actively exploited Windows kernel zero-day (CVE-2025-62215). The flaw is a race-condition and double-free that can let low-privileged local attackers corrupt kernel memory and escalate to system privileges, though exploitation requires precise timing and local code execution. Administrators should also prioritise a critical GDI+ RCE (CVE-2025-60724, CVSS 9.8) that can be triggered by parsing specially crafted metafiles. Microsoft additionally issued an out-of-band update (KB5071959) to resolve Windows 10 Consumer ESU enrollment failures.

Enterprise networks hit by legacy, unpatched systems

🔍 New research from Palo Alto Networks shows enterprise networks remain sprawling and poorly controlled: telemetry from 27 million devices across 1,800 enterprises found 26% of Linux and 8% of Windows systems running on end-of-life OS versions, 39% of directory-registered devices lack active endpoint protection, and 32.5% operate outside IT control. Poor segmentation — present in 77% of networks — and unmanaged edge devices increase attacker opportunities.

November 2025 Patch Tuesday: One Zero-Day, Five Criticals

🔒 Microsoft’s November 2025 Patch Tuesday addresses 63 CVEs, including one actively exploited zero‑day and five Critical vulnerabilities that span Windows, Office, Developer Tools and third‑party products.

CrowdStrike notes elevation of privilege, remote code execution and information disclosure are the leading exploitation techniques this month. Administrators should prioritize the zero‑day and Critical fixes (notably GDI+ and Nuance PowerScribe) and adopt mitigations where patching is delayed.

November Patch Tuesday: Critical Windows Kernel Zero-Day

⚠️ Microsoft’s November Patch Tuesday addresses 63 vulnerabilities, including an actively exploited Windows kernel zero-day CVE-2025-62215 that can allow local attackers to escalate to SYSTEM via a complex race-condition double-free.

Pixnapping vulnerability: Android screen-snooping risk

🔒 A newly disclosed exploit named Pixnapping (CVE-2025-48561) allows a malicious Android app with no special permissions to read screen pixels from other apps and reconstruct sensitive content. The attack chains intent-based off-screen rendering, translucent overlays, and a GPU compression timing side channel to infer pixel values. Google issued a September patch but researchers bypassed it, and a more robust fix is planned.
