IBM Sametime Meeting Server 8.5.2 and 9.0 is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM X-Force ID: 113945.

IBM Sametime 8.5 and 9.0 meetings server may provide detailed information in an error message that may provide details about the application to possible attackers. IBM X-Force ID: 113851.

The Meeting Server in IBM Sametime 8.x through 8.5.2.1 and 9.x through 9.0.0.1 does not include the HTTPOnly flag in a Set-Cookie header for an unspecified cookie, which makes it easier for remote attackers to obtain potentially sensitive information via script access to this cookie, a different vulnerability than CVE-2013-3984.

The Meeting Server in IBM Sametime 8.x through 8.5.2.1 and 9.x through 9.0.0.1 allows remote attackers to download avatar photos of arbitrary users via unspecified vectors.

Unspecified vulnerability in the Meeting Server in IBM Sametime 8.x through 8.5.2.1 and 9.x through 9.0.0.1 allows remote attackers to discover user names, full names, and e-mail addresses via a search.

The Meeting Server in IBM Sametime 8.x through 8.5.2.1 and 9.x through 9.0.0.1 does not check whether a session cookie is current, which allows remote attackers to conduct user-search actions by leveraging possession of a (1) expired or (2) invalidated cookie.

The Meeting Server in IBM Sametime 8.x through 8.5.2.1 and 9.x through 9.0.0.1 allows remote attackers to determine which meeting rooms are owned by a user by leveraging knowledge of valid user names.

The Meeting Server in IBM Sametime 8.x through 8.5.2.1 and 9.x through 9.0.0.1 allows remote attackers to cause a denial of service (room unusability) by generating a large number of fictitious users to enter a meeting room.

Cross-site scripting (XSS) vulnerability in the Meeting Server in IBM Sametime 8.x through 8.5.2.1 and 9.x through 9.0.0.1 allows remote authenticated users to inject arbitrary web script or HTML via a crafted URL.

The Meeting Server in IBM Sametime 8.x through 8.5.2.1 and 9.x through 9.0.0.1 does not send the HSTS Strict-Transport-Security header, which makes it easier for man-in-the-middle attackers to hijack sessions or obtain sensitive information by leveraging the presence of HTTP requests.
