88%of all CVEs are less likely

Readycheck to confirm it

The Certificate Signing Request (CSR) feature in the admin portal of the application is vulnerable to command injection. This vulnerability could allow authenticated admin users to execute arbitrary commands on the underlying server by injecting malicious input into the CSR generation process. The application failed to properly sanitize user-supplied input before using it in a command executed privileges.

Impact

Authenticated admin users can execute arbitrary OS commands on the TurboMeeting server through malicious CSR input, leading to complete system compromise and potential access to all meeting data.

Fix

Upgrade to the latest patched version of RHUB TurboMeeting or apply vendor-provided security updates.

How to confirm it

Send: POST /as/wapi/login
Positive when: contains "as/wapi/profile_entry?sid="
Send: @timeout: 20s
Positive when: contains "CSR" and "SSL" AND contains in interactsh_protocol "dns"
