radsecproxy is a generic RADIUS proxy that supports both UDP and TLS
(RadSec) RADIUS transports. Missing input validation in radsecproxy’s
naptr-eduroam.sh
and radsec-dynsrv.sh
scripts can lead to configuration
injection via crafted radsec peer discovery DNS records. Users are subject
to Information disclosure, Denial of Service, Redirection of Radius
connection to a non-authenticated server leading to non-authenticated
network access. Updated example scripts are available in the master branch
and 1.9 release. Note that the scripts are not part of the installation
package and are not updated automatically. If you are using the examples,
you have to update them manually. The dyndisc scripts work independently of
the radsecproxy code. The updated scripts can be used with any version of
radsecproxy.
