Security readout for executives and security teams
This is a remote code execution flaw in Apache Struts 2. An unauthenticated attacker could send a crafted HTTP header to a vulnerable server and run commands. It was exploited in the wild in March 2017 and is in CISA KEV, so exposed legacy Struts systems should be treated as urgent. Exposure is most likely on internet-facing Java applications or vendor products bundling vulnerable Apache Struts 2, especially routes that process multipart file uploads. Appliances or enterprise products should be checked against vendor advisories because Struts may be embedded and not obvious from application inventories. Immediate priority for any remaining Struts 2 exposure. This vulnerability is old but still business-critical because it is remotely exploitable, unauthenticated, publicly weaponized, and listed in KEV. Remediation should be tracked as an emergency legacy-risk closure item. Mitigation focus: Upgrade Apache Struts to 2.3.32, 2.5.10.1, or later supported releases.; Check vendor advisories for products that bundle Struts internally.; Prioritize externally reachable Struts applications and upload-handling routes..
