Apache OpenMeetings 1.0.0 uses not very strong cryptographic storage, captcha is not used in registration and forget password dialogs and auth forms missing brute force protection.
Apache OpenMeetings 1.0.0 is vulnerable to SQL injection. This allows authenticated users to modify the structure of the existing query and leak the structure of other queries being made by the application in the back-end.

Cross-site scripting (XSS) vulnerability in the SWF panel in Apache OpenMeetings before 3.1.2 allows remote attackers to inject arbitrary web script or HTML via the swf parameter.
The (1) FileService.importFileByInternalUserId and (2) FileService.importFile SOAP API methods in Apache OpenMeetings before 3.1.1 improperly use the Java URL class without checking the specified protocol handler, which allows remote attackers to read arbitrary files by attempting to upload a file.
Cross-site scripting (XSS) vulnerability in Apache OpenMeetings before 3.1.1 allows remote attackers to inject arbitrary web script or HTML via the event description when creating an event.
Directory traversal vulnerability in the Import/Export System Backups functionality in Apache OpenMeetings before 3.1.1 allows remote authenticated administrators to write to arbitrary files via a .. (dot dot) in a ZIP archive entry.
