Unspecified vulnerability in the webcontainer implementation in IBM Lotus Sametime Connect 8.5.1 before CF1 has unknown impact and attack vectors, aka SPRs LXUU87S57H and LXUU87S93W.

Stack-based buffer overflow in the Community Services Multiplexer (aka MUX or StMux.exe) in IBM Lotus Sametime 7.5.1 CF1 and earlier, and 8.x before 8.0.1, allows remote attackers to execute arbitrary code via a crafted URL.

The default configuration of the Sametime configuration servlet (SCS) in the server in IBM Lotus Sametime 7.0 through 8.5.2 does not enable an authentication requirement, which allows remote attackers to read the configuration settings by examining a response message.

Cross-site scripting (XSS) vulnerability in the chat client in IBM Lotus Sametime 7.5 and 7.5.1 allows user-assisted remote attackers to inject arbitrary web script or HTML via a crafted message, which triggers code execution after a mouseover event initiated by the victim.
