CVE-2017-5648
CriticalSummary
In Apache Tomcat versions from 9.0.0.M1 to 9.0.0.M17, 8.5.0 to 8.5.11, 8.0.0.RC1 to 8.0.41, and 7.0.0 to 7.0.75, there was an issue with the use of the incorrect facade object in some calls to application listeners. This allowed untrusted applications to retain a reference to the request or response object, potentially accessing or modifying information associated with another web application.
Risk Assessment
The organization may be exposed to attacks where untrusted applications can access data from other applications, leading to information leakage or modification.
Recommendation
It is recommended to update Apache Tomcat to the latest version to mitigate this vulnerability and review the security of applications running in a SecurityManager environment.
Original NVD description (English source)
While investigating bug 60718, it was noticed that some calls to application listeners in Apache Tomcat 9.0.0.M1 to 9.0.0.M17, 8.5.0 to 8.5.11, 8.0.0.RC1 to 8.0.41, and 7.0.0 to 7.0.75 did not use the appropriate facade object. When running an untrusted application under a SecurityManager, it was therefore possible for that untrusted application to retain a reference to the request or response object and thereby access and/or modify information associated with another web application.
