The HTTP/2 implementation in Apache Tomcat 9.0.0.M1 to 9.0.0.M21 and 8.5.0 to 8.5.15 bypassed a number of security checks that prevented directory traversal attacks. It was therefore possible to bypass security constraints using a specially crafted URL.

Security readout for executives and security teams

CVE-2017-7675 is an Apache Tomcat HTTP/2 flaw that could let a crafted URL bypass security constraints intended to stop directory traversal. The risk is highest for internet-facing Tomcat services using affected 8.5.x or 9.0 milestone versions with HTTP/2 enabled. Exposure is likely limited to Apache Tomcat deployments in the listed version ranges, especially where HTTP/2 is enabled and protected content depends on Tomcat security constraints. Prioritize remediation for public or partner-facing Tomcat services because the issue can undermine access controls. Internal-only systems still warrant tracking, but urgency depends on network reachability and whether HTTP/2 is enabled. Mitigation focus: Inventory Apache Tomcat versions across internet-facing and internal services.; Treat Tomcat 8.5.0-8.5.15 and 9.0.0.M1-M21 as vulnerable.; Follow the Apache Tomcat security announcement for supported remediation guidance..
