Jason Soroko, senior fellow at Sectigo, is extra anxious in regards to the blast radius of a possible exploit. “ISE sits on the very fringe of belief for a lot of campus networks, and a breach can rewrite entry insurance policies, transfer endpoints between VLANs, and open pivots into each phase,” he stated. “The weak API is usually reachable from broad inner tackle ranges, generally even visitor Wi-Fi, and ISE patching requires disruptive upkeep home windows.”
Lively focusing on feels possible as a result of the failings (CVE-2025-20281) already attracted public proof-of-concept exploits and scan visitors inside days, Soroko added.
For extra safety, Barr recommends utilizing specialised API security options that may detect and block anomalous API exercise in actual time, present endpoint-risk scoring, and cease automated scanning and payload supply.
