“CISA and NSA have issued guidance about architecture, exposure, and management-plane hygiene, which goes beyond typical CVE-by-CVE patching,” Prabhu said. “Attackers are targeting the SD-WAN controller to gain fabric-wide control over routing, segmentation, and security policy, which can impact many sites at once. This warrants treating SD-WAN managers as Tier-0 assets: isolate and harden them, tightly control and monitor access, and assume potential controller compromise in your architecture.”
Datta said CISOs should not treat flaws in network orchestration platforms as routine patching events because the management plane is a central trust layer in software-defined infrastructure.
“When a platform repeatedly suffers from structural weaknesses such as insufficient input validation or authentication bypasses, it signals that the vendor’s internal secure software development lifecycle (SDLC) is struggling to defend its core trust boundaries,” Datta said.
