On December 3, 2025, the React team publicly disclosed a critical security vulnerability affecting React Server Components. The flaw has been assigned the identifier CVE-2025-55182 and carries a maximum severity rating. This issue enables unauthenticated remote code execution under certain conditions, making it one of the most serious web-framework vulnerabilities disclosed in recent years. The timing and severity of this disclosure matter. React, along with frameworks like Next.js, powers a significant percentage of modern web applications, including enterprise portals, SaaS platforms, e-commerce systems, and internal business applications. The presence of a remotely exploitable vulnerability in a default configuration elevates the risk far beyond niche developer scenarios. What Caused the Vulnerability The vulnerability originates within the implementation of the React Server Components protocol, often referred to as the Flight protocol. Specifically, the server logic responsible for interpreting RSC payloads fails to adequately validate and constrain the data received from remote clients.…

On October 31, 2025, the Cybersecurity and Infrastructure Security Agency (CISA), National Security Agency (NSA), and several international partners released a new security blueprint for hardening Microsoft Exchange servers. This release isn't just another best-practice document-it's a wake-up call for organizations still hosting or maintaining on-prem Exchange environments. For those relying on hybrid email infrastructures, this guidance may be the difference between staying secure and becoming a headline. At Critical Path Security, we've spent years helping organizations navigate complex Exchange, Microsoft 365, and hybrid configurations through our Secure Cloud Business Applications (SCuBA) assessments. This blueprint validates what we've been preaching: legacy Exchange environments are one of the most consistent entry points for attackers targeting both IT and OT environments. Why This Blueprint Matters Exchange has long been a favourite target of cyber threat actors. When compromised, it becomes a stepping stone-offering direct access to internal systems, cloud connectors, and even…

At Critical Path Security, we've always believed that compliance shouldn't be a guessing game-and security shouldn't rely on a checklist. Starting this month, every Managed SOC subscription now includes monthly SCuBA (Secure Cloud Business Applications) scans as part of our standard service. No upsells. No hidden fees. Just better visibility. The SCuBA framework, developed by CISA, is designed to assess Microsoft 365, Google Workspace, and related cloud environments against rigorous, government-grade baselines. By integrating it into our Managed SOC platform, we're bringing the same federal-level scrutiny directly to your organization-automatically, every month. What this means for you: Continuous validation of your cloud security posture Evidence-based alignment with NIST and CMMC controls Immediate remediation guidance for misconfigurations and risky settings Monthly executive summaries delivered alongside your SOC reporting Our analysts already monitor your endpoints, logs, and networks for threats in real time. Now, we're adding a new layer-continuous cloud configuration assurance-so…

When cyber criminals go after routers and switches, it's not noise. It's control.This week, reports confirmed that threat actors are exploiting a critical vulnerability in Cisco's SNMP implementation (CVE 2025 20352) to deploy a rootkit on network switches. It's another reminder that the infrastructure we rely on to see and defend our networks can also be turned against us. At Critical Path Security, we've seen how these attacks evolve. A simple SNMP exposure turns into silent persistence, lateral movement, and data manipulation inside critical environments. This one is especially dangerous. What Happened Cisco IOS and IOS XE systems running certain builds are vulnerable to remote code execution through their SNMP stack. Once cyber criminals reach the SNMP interface, often left open for device management, they can execute code as root. The exploit, active in the wild before Cisco's advisory, targets several popular switch families: 9400, 9300, and the legacy 3750G.…
