Name of the Vulnerable Software and Affected Versions
Coturn versions prior to 4.13.1
Description
The
good peer addr() function in src/server/ns turn server.c utilizes ioa addr in range() in src/client/ns turn ioaddr.c without canonicalizing IPv4-compatible, 6to4, and 64:ff9b::/96 NAT64 address forms. This allows an authenticated RFC 6062 TCP CONNECT relay client to bypass an IPv4 denied-peer-ip range if the host has a suitable translation route.Recommendations
Update to version 4.13.1.
