Remove double quotes from variable

[Raghu nathan]

We are calling %{Module-Failure-Message} in linelog and trying to create
JSON logs.

But we are getting sometime error with double quotes, which is creating
issue on JSON spec.

For example,
In linelog messages we have below entry

Access-Reject = "{\"Datetime\":\"%t\",\
\"Packet-Type\":\"%{reply:Packet-Type}\",\
\"User-Name\":\"%{User-Name}\",\
\"Module-Failure-Message\":\"%{Module-Failure-Message}\"\
}"
We are getting the logs as

{"Datetime":"Fri Oct 26 09:07:17
2018","Packet-Type":"Access-Reject","User-Name":"CONSUMER4.TATA","Module-Failure-Message":"pap:
Cleartext password "WRONG-PASSWORD" does not match "known good" password"}


In the Module-Failure-Message output we are receiving the message with
double quotes which is not as per JSON standard.
Please let me know how I can solve the issue without doing any coding.

Regards,
Raghu.

Use the jsonquote xlat on any untrusted data that comes in the request
(e.g. User-Name as well, as that can be controlled by the connecting
device).

..., \"Module-Failure-Message\":\"%{jsonquote:%{Module-Failure-Message}}\", ...

Thanks Matthew,

We are using centos 7 and freeRADIUS 3.0.13

Now we are missing "/usr/lib64/freeradius/rlm_rest.so" , I have
installed using stable release.
Please let us know how we can install this library?

Error:
/etc/raddb/mods-enabled/rest[1]: Failed to link to module 'rlm_rest':
/usr/lib64/freeradius/rlm_rest.so: cannot open shared object file: No such

There probably is a freeradius-rest-package you need to install.
