Base vector

AV:N/AC:L/Au:N/C:C/I:C/A:C

Name of the Vulnerable Software and Affected Versions coTURN versions prior to 4.5.0.9

Description The issue is related to an error in encoding registration data in the coTURN server function. This can allow a remote attacker to gain administrator access to the server via the telnet port. The TURN server has an unauthenticated telnet admin portal on the loopback interface by default, which can provide administrator access to the server configuration and lead to additional attacks.

Recommendations For coTURN versions prior to 4.5.0.9, update to version 4.5.0.9 or later to resolve the issue. As a temporary workaround, consider restricting access to the telnet port to minimize the risk of exploitation.
