CVE-2016-0783
The sendHashByUser function in Apache OpenMeetings before 3.1.1 generates predictable password reset tokens, which makes it easier for remote attackers to reset arbitrary user passwords by leveraging knowledge of a user name and the current system time.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (7.10%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
