CVE-2018-8037 Apache Tomcat - Information Disclosure
Severity: Important
Vendor: The Apache Software Foundation
Versions Affected:
Apache Tomcat 9.0.0.M9 to 9.0.9
Apache Tomcat 8.5.5 to 8.5.31
Description:
If an async request was completed by the application at the same time as
the container triggered the async timeout, a race condition existed that
could result in a user seeing a response intended for a different user.
An additional issue was present in the NIO and NIO2 connectors that did
not correctly track the closure of the connection when an async request
was completed by the application and timed out by the container at the
same time. This could also result in a user seeing a response intended
for another user.
Mitigation:
Users of the affected versions should apply one of the following
mitigations:
- Upgrade to Apache Tomcat 9.0.10 or later.
- Upgrade to Apache Tomcat 8.5.32 or later.
