The hash generated by the external password reset function is generated by concatenating the user name and the current system time, and then hashing it using MD5. This is highly predictable and can be cracked in seconds by an attacker with knowledge of the user name of an OpenMeetings user. Apache OpenMeetings versions 1.9.x through 3.1.0 are affected.
