In partnership with
In the last 72 hours, threat actors made notable moves: CISA added two new vulnerabilities to its Known Exploited Vulnerabilities Catalog on November 4. Cisco warned of a fresh attack variant leveraging CVE‑2025‑20333 and CVE‑2025‑20362 in ASA/FTD firewalls. And a widely-used Linux server control panel, Control Web Panel (CWP), saw remote code-execution exploitation of CVE‑2025‑48703 across ~220 000 exposed hosts.Share the newsletter

Top-level takeaways this week:
Infrastructure & Edge Exploitation ↑ — Cisco’s new firewall-attack variant underlines risk in core network gear.
Toolchain / Admin Panel Risk ↑ — The Control Web Panel RCE shows that the attack surface extends into web-host management platforms.
Zero-Day / Exploit Velocity ↑ — CISA’s new KEV additions mean attackers are already active; patch windows continue to shrink.
1) Cisco firewall vulnerabilities (CVE-2025-20333 & CVE-2025-20362) exploited – High
What changed: Cisco released updated advisories confirming active attacks targeting ASA and FTD appliances, including DoS and RCE variants.
Why this matters: Network-edge devices are high-value targets—compromise here gives attackers control of traffic flow, inspection bypass, and deeper persistence.
2) Control Web Panel RCE (CVE-2025-48703) used in attacks – High
What changed: CISA added this flaw to the KEV catalog and alerts note widespread exposure of vulnerable CWP hosts (~220 000 globally).
Why this matters: Admin panels and hosting control systems provide “stealth pivot” paths from untrusted servers into corporate assets—often bypassing traditional perimeter protections.
3) CISA adds two new flaws to KEV catalog – Medium
What changed: On Nov 4, CISA announced that two additional vulnerabilities with confirmed exploit evidence were added to the Known Exploited Vulnerabilities list.
Why this matters: Inclusion in KEV means the vulnerability is operationalized. Unpatched systems now carry both technical and compliance risk.
Stage | Vector | What We’re Seeing |
|---|---|---|
Initial Access | Admin-tool / control panel RCE | The CWP flaw shows management consoles are exploited as entry points. |
Lateral / Persist | Edge device code execution | Cisco ASA/FTD variants demonstrate foundational network gear is under active attack. |
Impact | Data interception + system takeover | Attackers weaponize infrastructure for persistence, routing, and exfil, not just encryption. |

🔄 Patch & Hardening
Apply firmware/software updates for Cisco ASA/FTD addressing CVE‑2025‑20333 and CVE‑2025‑20362 immediately.
Isolate or patch all Control Web Panel instances vulnerable to CVE‑2025‑48703; restrict port 2083 access to trusted IPs.
Review edge-device exclusion lists and network segmentation around admin consoles and hosting control panels.
📊 People & Monitoring
Alert on unexpected reloads or configuration changes in firewall/VPN/ASA gear during off-hours.
Monitor for new admin accounts, shell drops, or reverse connections from previously benign CWP hosts.
Confirm that your KEV-remediation tracker includes today’s additions and show progress by EOD.
💼 Process & Validation
Freeze changes to firewall or web-hosting control-panel configurations unless explicitly approved by the CISO.
Conduct a brief tabletop for scenario: “Firewall RCE → control-panel pivot → exfiltration/traffic hijack.”
🤝 Partners & Assurance
Require MSPs/hosting providers to certify that Edge gear (ASA/FTD) is patched and logs are forwarded to SIEM.
Ask web-hosting vendors to audit for CWP exposures and confirm inventory of version-tracked instances.
Zero-days and legacy flaws are converging - new (WhatsApp, Apriso) and old (SonicWall) vulnerabilities are live.
Mobile spyware is stealthy and immediate - executives’ phones are espionage goldmines.
Insider threats are not hypothetical - even students are becoming an active attack surface.
🔄 Verify: All ASA/FTD firewall instances are patched or isolated and configuration change monitoring is in place.
📊 Validate: Hosting/control-panel instances (CWP, etc.) are inventoried, patched or segmented, and logs are actively reviewed.
💼 Confirm: KEV remediation tracker is current and shows closure or planned mitigation for new listings.
🔹 Rehearse: Monday tabletop: “Net-edge device compromise → hosting console pivot → enterprise infiltration.”
Final Insight: This week reinforces a simple truth: attackers no longer start with end-users.. they start with the tools that manage end-users. If you want a quiet weekend, treat your infrastructure like your firewall policy… no exceptions, no shortcuts.
