IBM WebSphere eXtreme Scale 7.1.0 before 7.1.0.3, 7.1.1 before 7.1.1.1, 8.5 before 8.5.0.3, and 8.6 before 8.6.0.8 does not properly encrypt data, which makes it easier for remote attackers to obtain sensitive information by sniffing the network.

CRLF injection vulnerability in IBM WebSphere eXtreme Scale 7.1.0 before 7.1.0.3, 7.1.1 before 7.1.1.1, 8.5 before 8.5.0.3, and 8.6 before 8.6.0.8 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via a crafted URL.

IBM WebSphere eXtreme Scale Client 7.1 through 8.6.0.4 does not properly isolate the cached data of different users, which allows remote authenticated users to obtain sensitive information in opportunistic circumstances by leveraging access to the same web container.
