Cross-site scripting (XSS) vulnerability in the Web Application in the Classic Meeting Server in IBM Sametime 7.5.1.2 through 8.5.2.1 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

The Connect client in IBM Sametime 8.5.2 through 8.5.2.1 and 9.0 before HF1 does not properly restrict unsigned Java plugins, which allows remote attackers to obtain sensitive information via unspecified vectors.

The Meeting Server in IBM Sametime 8.5.2 through 8.5.2.1 and 9.x through 9.0.0.1 does not validate URLs in Cookie headers before using them in redirects, which has unspecified impact and remote attack vectors.

The Meeting Server in IBM Sametime 8.5.2 through 8.5.2.1 and 9.x through 9.0.0.1 does not send the appropriate HTTP response headers to prevent unwanted caching by a web browser, which allows remote attackers to obtain sensitive information by leveraging an unattended workstation.

The Meeting Server in IBM Sametime 8.5.2 through 8.5.2.1 and 9.x through 9.0.0.1 allows remote attackers to conduct clickjacking attacks via unspecified vectors.

The client implementation in IBM Sametime 8.5.1 through 8.5.2.1, as used in Sametime Connect client, Sametime Advanced Connect client, Sametime Advanced Web client, and other products, allows remote authenticated users to send commands to individual chat users, or to all participants in a chat room, via a crafted Sametime Instant Message (IM).

The Connect client in IBM Sametime 8.5.1, 8.5.1.1, 8.5.1.2, 8.5.2, and 8.5.2.1, as used in the Lotus Notes client and separately, might allow local users to obtain sensitive information by leveraging the persistence of cleartext password strings within process memory.

IBM Sametime allows remote attackers to obtain sensitive information from the Sametime Log database via a direct request to STLOG.NSF. IBM X-Force ID: 78048.
