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.

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 obtain unspecified installation information and technical data via a request to a public page.

The Meeting Server in IBM Sametime 8.x through 8.5.2.1 and 9.x through 9.0.0.1 does not set the secure flag for an unspecified cookie in an https session, which makes it easier for remote attackers to capture this cookie by intercepting its transmission within an http session.

The Connect client in IBM Sametime 8.5.1, 8.5.1.1, 8.5.1.2, 8.5.2, 8.5.2.1, 9.0, and 9.0.0.1, when a certain com.ibm.collaboration.realtime.telephony.*.level setting is used, logs cleartext passwords during Audio/Video chat sessions, which allows local users to obtain sensitive information by reading a log file.

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 does not validate URLs in Cookie headers before using them in redirects, which has unspecified impact and remote attack vectors.

Cross-site scripting (XSS) vulnerability in the Meeting Server in IBM Sametime 8.5.2 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 vectors involving an IMG element.

The Meeting Server in IBM Sametime 8.5.2 through 8.5.2.1 and 9.x through 9.0.0.1 do not have an off autocomplete attribute for a password field, which makes it easier for remote attackers to obtain access by leveraging an unattended workstation.
