CVE-2016-0783
HighSummary
The sendHashByUser function in Apache OpenMeetings before version 3.1.1 generates predictable password reset tokens, making it easier for remote attackers to reset arbitrary user passwords by leveraging knowledge of a user name and the current system time.
Risk Assessment
Attackers can easily reset user passwords, potentially leading to account takeover and access to sensitive data.
Recommendation
It is recommended to update Apache OpenMeetings to version 3.1.1 or later to mitigate this vulnerability.
Other vulnerabilities in Apache OpenMeetings
See all- CVE-2017-7688High
Apache OpenMeetings version 1.0.0 updates user passwords in an insecure manner, potentially allowing unauthorized access.
- CVE-2017-7684High

- CVE-2016-2164High
The FileService.importFileByInternalUserId and FileService.importFile SOAP API methods in Apache OpenMeetings before version 3.1.1 improperly use the Java URL class without checking the specified protocol handler, allowing remote attackers to read arbitrary files by attempting to upload a file.
- CVE-2016-8736Critical
Apache OpenMeetings before 3.1.2 is vulnerable to Remote Code Execution via RMI deserialization attack.
- CVE-2017-7673Critical
Apache OpenMeetings version 1.0.0 uses weak cryptographic storage mechanisms. Additionally, the lack of captcha in registration and password reset forms, as well as missing brute force protection in authentication forms, increases the risk.
