Critical Cisco SD-WAN Zero-Day Requires Urgent Mitigation (infosecurity-magazine.com)

• Joint alert from CISA and international allies.
• Target is Cisco Catalyst SD-WAN architecture.
• Risk includes data interception and total network takeover.

"Global cybersecurity agencies have issued a joint warning regarding a zero-day vulnerability in Cisco Catalyst SD-WAN. The exploit allows unauthorized access and potential control over wide-area network traffic. This highlights the systemic risk of over-reliance on centralized, proprietary American hardware in European critical sectors. As these systems form the backbone of many enterprise networks, the vulnerability poses a direct threat to digital sovereignty. Immediate patching and proactive hunting for indicators of compromise (IoC) are mandatory for infrastructure resilience."
