TLS 1.3 enabled or not?
by Luca Borruto 27 Sep '24

27 Sep '24

Hi everyone! Have you enabled TLS 1.3 in your configuration? I read somewhere it can cause issues, but we mostly use recent Windows and macOS machines, and I was wondering if we could benefit from it. tls_min_version = 1.2 tls_max_version = 1.3 Thanks !

Investigating Slow RADIUS Proxy Request
by Vedsar Kushwaha 27 Sep '24

27 Sep '24

I have a few questions about how the FreeRADIUS proxy handles requests: 1. When proxying a request, does a FreeRADIUS thread remain blocked until a response is received from the home server? 2. Does the max_outstanding flag apply only to health status checks, or does it affect all requests proxied to the home server? * If a FreeRADIUS thread blocks while waiting for a response, does increasing max_outstanding to a high value like 65536 actually allow FreeRADIUS to send that many outstanding requests? Or is the number of threads the limiting factor? * If a proxy request doesn't block a thread, how does FreeRADIUS listen for responses from the home server? 1. We have a request that took 40 minutes to proxy. The snippet below, along with the complete log, shows the details. We're trying to investigate the cause of this delay. ``` 2024-09-17T13:05:52.495Z (44469) Starting proxy to home server 129.170.130.4 port 2083 2024-09-17T13:05:52.495Z (44469) server VS_P_790be815-af8f-4dc5-b8c2-e01b8a107db4 { 2024-09-17T13:05:52.495Z (44469) } 2024-09-17T13:46:55.967Z (44469) Proxying request to home server 129.170.130.4 port 2083 (TLS) timeout 30.000000 ``` Juniper Business Use Only

Consult accounting-reponse related issues
by 杨思雷 27 Sep '24

27 Sep '24

Hi， When proxying a accounting-request, does FreeRadius must listen for responses from the home server? If I only want the Freeradius proxy accounting-request to the home server, and do not care of the respose, what can I do?

Issue with 3.2.6 - dies/stops serving but is still running/listening on port
by James Wood 27 Sep '24

27 Sep '24

Since upgrading to 3.2.6 we're seeing an issue where the radiusd program just "dies" and stops receiving/handling requests, yet the program itself is still running, has a PID, and netstat shows it's still listening on the ports. I can see the requests still reaching the machine via tcpdump but nothing from radiusd. We're using TLS to support EAP connections but no clients are using TLS on this particular server so it's all UDP, though TLS is still enabled and listening. OpenSSL version is 3.0.2 I've included some logs from what little I know about gdb and wondered if anyone can advise the likely culprit of the issue. The last entries in radius.log were normal authentications and then it just died and stopped receiving requests. I've also observed the same in debug mode, nothing is showing untoward in the output on screen before it dies.

Add TLS version to logs with linelog in FreeRADIUS 3.2.4
by dominic.stalder＠unibe.ch 26 Sep '24

26 Sep '24

Hi guys A few weeks back, I used FreeRADIUS 3.0.26 on Ubuntu 22.04.4 LTS before upgrading to FreeRADIUS 3.2.4 (NetworkRADIUS packages). Everything works great so far, except two attributes are missing in our logs since then: TLS-Session-Version and TLS-Session-Cipher-Suite. My /etc/freeradius/mods-available/linelog configuration looked like this on FreeRADIUS 3.0.x: sp { Access-Accept = "%t : AuthZ: (%I) Access-Accept: [%{%{reply:User-Name}:-%{User-Name}}] TLS-Version=%{%{session-state:TLS-Session-Version}:-NULL} TLS-Ciphers=%{%{session-state:TLS-Session-Cipher-Suite}:-NULL} SSID=%{%{request:Called-Station-SSID}:-NULL} Calling-Station-Id=%{%{request:Calling-Station-Id}:-Unknown} Called-Station-Id=%{%{request:Called-Station-Id}:-Unknown} Filter-ID=%{%{reply:Filter-Id}:-NULL} VLAN=%{%{reply:Tunnel-Private-Group-Id}:-NULL} Class=%{%{reply:Class}:-NULL} (from client %{Client-Shortname} port %{%{request:Nas-Port}:-0} cli %{%{request:Calling-Station-Id}:-Unknown})" } When I start the debugging (see full output below), I can see the following attributes, which I could use / log now: (10) eap_peap: TLS-Session-Cipher-Suite = "ECDHE-RSA-AES256-GCM-SHA384" (10) eap_peap: TLS-Session-Version = "TLS 1.2" When I try to “access” them in the linelog configuration like this… sp { Access-Accept = "%t : AuthZ: (%I) Access-Accept: [%{%{reply:User-Name}:-%{User-Name}}] TLS-Test=%{%{eap_peap:TLS-Session-Version}:-NULL} TLS-Version=%{%{session-state:TLS-Session-Version}:-NULL} TLS-Ciphers=%{%{session-state:TLS-Session-Cipher-Suite}:-NULL} SSID=%{%{request:Called-Station-SSID}:-NULL} Calling-Station-Id=%{%{request:Calling-Station-Id}:-Unknown} Called-Station-Id=%{%{request:Called-Station-Id}:-Unknown} Filter-ID=%{%{reply:Filter-Id}:-NULL} VLAN=%{%{reply:Tunnel-Private-Group-Id}:-NULL} Class=%{%{reply:Class}:-NULL} (from client %{Client-Shortname} port %{%{request:Nas-Port}:-0} cli %{%{request:Calling-Station-Id}:-Unknown})" } } …I get the following error in the debug output: (21) 802.1x_authz_log: ERROR: %t : AuthZ: (%I) Access-Accept: [%{%{reply:User-Name}:-%{User-Name}}] TLS-Test=%{%{eap_peap:TLS-Session-Version}:-NULL} TLS-Version=%{%{session-state:TLS-Session-Version}:-NULL} TLS-Ciphers=%{%{session-state:TLS-Session-Cipher-Suite}:-NULL} SSID=%{%{request:Called-Station-SSID}:-NULL} Calling-Station-Id=%{%{request:Calling-Station-Id}:-Unknown} Called-Station-Id=%{%{request:Called-Station-Id}:-Unknown} Filter-ID=%{%{reply:Filter-Id}:-NULL} VLAN=%{%{reply:Tunnel-Private-Group-Id}:-NULL} Class=%{%{reply:Class}:-NULL} (from client %{Client-Shortname} port %{%{request:Nas-Port}:-0} cli %{%{request:Calling-Station-Id}:-Unknown}) (21) 802.1x_authz_log: ERROR: ^ Unknown module Any hint, how I can “access” those two attributes in FreeRADIUS 3.2.4 correctly? (10) eap_peap: TLS-Session-Cipher-Suite = "ECDHE-RSA-AES256-GCM-SHA384" (10) eap_peap: TLS-Session-Version = "TLS 1.2" Thanks in advance and best regards Dominic *** Full debug output:

Force reauth possible? (INTERNAL)
by Per Weisteen 26 Sep '24

26 Sep '24

Hi I may have asked this before but can't find any references or replies. Anyway, I'm running FreeRADIUS 3.2.6 and I'm using EAP-TLS only. When a device has authenticated it seems to be in that state forever until it reboots or loses its network connection. Is there any parameter I could set that would force my devices to re-authenticate after a certain amount of time? ./PerW Sensitivity: Internal

802.1x and MAC Authentication
by Connor Herring 24 Sep '24

24 Sep '24

Hi All, I am attempting to setup my server so that it now checks a MAC address and then provided the MAC address is ok it then moves on to performing EAP authentication. This seems to be working fine but I noticed something in the logs that I wanted to query. I am using this guide <https://wiki.freeradius.org/guide/Mac-auth#mac-auth-and-802-1x>. Whenever the RADIUS server sends an Access-Challenge, it still sends the usual EAP-Message, Message-Authenticator, and State attributes, however it now also sends a Reply-Message on the line above these in the format of the one in the aforementioned guide: Reply-Message = "Device with MAC Address %{Calling-Station-Id} authorized for network access" Doesn't seem like something to worry about just wondered if there was any way around this? Further to this the guide says: if (!ok) { # Reject if the MAC address was not permitted. reject } # If this is NOT 802.1x, mac-auth if (!EAP-Message) { # MAC address has already been checked, so accept update control { Auth-Type := Accept Unless I am misunderstanding this is saying, "check the MAC address, if this isn't correct then continue. If it is correct but someone isn't using EAP then just allow them through". Surely unless someone were to comment out all authentication modules besides EAP in the default server, this would just allow someone to get onto the network with a correct MAC even if they don't have auth credentials? Kind regards, Connor

Re: Windows Slow EAP-TLS Authentication
by George Benjin 20 Sep '24

20 Sep '24

You need to be very careful running a RADIUS server in Azure if you're using RADIUS/UDP. Azure has a network security feature on by default that drops fragmented UDP packets that arrive out of order. This negatively impacts RADIUS/UDP traffic. To give you an example, at least 20% of EAP-TLS auth attempts were failing for us in the cert auth phase due to this issue. Azure support can turn on the 'enable-udp-fragment-reordering' feature by request after providing packet captures and use case info etc. They will also only turn it on in a brand new subscription that's dedicated to running VMs that require this feature. After we did this, our auth success rate increased to 100%. Another thing to be wary of is setting 'tls_max_version' to 1.3. Windows 11 supports TLS 1.3 by default for EAP-TLS etc but does not yet support session resumption when using this protocol (see https://learn.microsoft.com/en-us/windows-server/networking/technologies/ex…) It's worth dropping the Max version to 1.2.

SQL Injection
by Connor Herring 19 Sep '24

19 Sep '24

Hi All, Hopefully a quick one, is the SQL module still susceptible to SQL injection in version 3.2.1 of FreeRADIUS? I was having a look through implementing some anti SQL injection measures since I found a security notification on the FreeRADIUS site for it, but given that it is quite an old notification, is this still required? If it is, are there any recommended measures? Kind regards, Connor

EAP-TLS not working with ECC Keys
by n5d9xq3ti233xiyif2vp＠pm.me 19 Sep '24

Hi What am I missing to get EAP working both radius server and clients having ECC (P521) keys ? Running freeradius in the foreground shows me this: (8) eap_tls: (TLS) EAP Peer says that the final record size will be 378 bytes (8) eap_tls: (TLS) EAP Got all data (378 bytes) (8) eap_tls: (TLS) recv TLS 1.3 Handshake, ClientHello (8) eap_tls: (TLS) Handshake state - Server SSLv3 read client hello A (8) eap_tls: (TLS) send TLS 1.3 Handshake, ServerHello (8) eap_tls: (TLS) Handshake state - Server SSLv3 write server hello A (8) eap_tls: (TLS) send TLS 1.3 Handshake, type=8 (8) eap_tls: (TLS) send TLS 1.3 Handshake, CertificateRequest (8) eap_tls: (TLS) Handshake state - Server SSLv3 write certificate request A (8) eap_tls: (TLS) send TLS 1.3 Alert, fatal handshake_failure (8) eap_tls: ERROR: (TLS) Server : Error in SSLv3 write certificate A (8) eap_tls: ERROR: (TLS) Failed reading from OpenSSL (8) eap_tls: ERROR: (TLS) error:1402D0FB:SSL routines:ACCEPT_SW_CERT:unknown pkey type (8) eap_tls: ERROR: (TLS) error:14FFF0A8:SSL routines:(UNKNOWN)SSL_internal:missing rsa certificate (8) eap_tls: ERROR: (TLS) System call (I/O) error (-1) (8) eap_tls: ERROR: (TLS) EAP Receive handshake failed during operation "missing rsa certificate" is the bit that jumps out at me. My /etc/raddb/mods-available/eap file looks like the following: eap { default_eap_type = tls timer_expire = 60 ignore_unknown_eap_types = no cisco_accounting_username_bug = no max_sessions = ${max_requests} tls-config tls-common { private_key_password = THIS_HAS_BEEN_REMOVED_TO_PROTECT_THE_INNOCENT private_key_file = /etc/foobar/wifi/cert-out.key certificate_file = /etc/foobar/wifi/cert-out.crt ca_file = /etc/foobar/wifi/ca-chain.pem dh_file = /etc/foobar/wifi/dh.pem ca_path = ${cadir} cipher_list = "DEFAULT" cipher_server_preference = no tls_min_version = "1.2" tls_max_version = "1.3" ecdh_curve = "secp521r1" cache { enable = no store { Tunnel-Private-Group-Id } } verify { } ocsp { enable = no override_cert_url = yes url = "http://127.0.0.1/ocsp/" } } tls { tls = tls-common } }
