Title:Apache Tomcat HTTP/2 Vulnerability - Oct20 (Windows)
Summary:Apache Tomcat is prone to an information disclosure vulnerability in HTTP/2.
Description:Summary:
Apache Tomcat is prone to an information disclosure vulnerability in HTTP/2.

Vulnerability Insight:
If an HTTP/2 client exceeded the agreed maximum number of concurrent streams
for a connection (in violation of the HTTP/2 protocol), it is possible that a subsequent request made on that
connection could contain HTTP headers - including HTTP/2 pseudo headers - from a previous request rather than
the intended headers. This could lead to users seeing responses for unexpected resources.

Affected Software/OS:
Apache Tomcat 8.5.1 to 8.5.57, 9.0.0.M5 to 9.0.37 and 10.0.0-M1 to 10.0.0-M7.

Solution:
Update to version 8.5.58, 9.0.38, 10.0.0-M8 or later.

CVSS Score:
4.0

CVSS Vector:
AV:N/AC:L/Au:S/C:P/I:N/A:N
