Sukchan Lee 390a9dd637 [MME] incorrect behavior of the SGsAP 
1. According to ETSI TS 129 118 4.1, if the Network Access Mode (NAM) is set
   to "Packet only," no SGs association should be established.

2. If the NAM is set to "Packet and Circuit," and the SGs association is
   rejected by the CS core, this rejection should only impact
   the SGs association itself and not result in a UE attach rejection
   for a UE with a valid HSS account.

Sukchan Lee 7c14073533 [UDM] Added validation for pubkey 
a cryptographic vulnerability in the SUCI decryption routines
of Open5GS 5G—specifically Profile B, which uses P-256 (secp256r1)
for its elliptic curve routines.

If a mobile device user passes a public key within its SUCI
that does not correspond to a valid point on the P-256 elliptic curve,
the Open5GS UDM will not check the point
before running elliptic curve operations with it and returning a response
to the mobile device user.

If the public key is not checked to be a valid point, an attacker can leverage
this behavior to extract the Profile B private key from the UDM,
as has been done in other domains
(https://owasp.org/www-pdf-archive/Practical_Invalid_Curve_Attacks_on_TLS-ECDH_-_Juraj_Somorovsky.pdf).

Note that Profile A is not similarly vulnerable to this, as it is impossible
to construct an invalid point on a curve25519 elliptic curve.

There was some work that went into developing a practical proof of concept
of this kind of attack against free5gc last year; it can be found here:

https://www.gsma.com/security/wp-content/uploads/2023/10/0073-invalid_curve.pdf

And here is the free5gc security advisory:

https://github.com/advisories/GHSA-cqvv-r3g3-26rf

To mitigate this issue in Open5GS, the public key of the UE must be validated
by the UDM prior to use. Adding a validation function such as the following
should work:

I designed this code based on information from https://crypto.stackexchange.com/questions/90151/verify-that-a-point-belongs-to-secp256r1.

Sukchan Lee cf4ad1f248 [PFCP] Session removal while waiting PFCP reply (#3040) 
'node_timeout' and some other functions can remove a smf_sess_t
while that session is still waiting for a PFCP reply
and has an active PFCP xact.

In this case, xact->data points to the deleted session
and xact's timeout function (sess_5gc_timeout for example)
eventually refers to this already freed session.

This fix prevents duplicate deletes from occurring by checking to see
if the session context has already been deleted when the timeout occurs.

Additionally, it moves session deletions out of timer callbacks into
state machine by reselect_upf().

Due to the way 'ogs_timer_mgr_expire' calls timer callbacks,
one must not stop or expire timers from within a timer callback.

And now one must not remove sessions from within a timer callback.

Sukchan Lee a667525041 [GTP/PFCP]] incorrect dst TEI=0/SEID=0 (#3043) 
If eg. PCRF or AAA diameter link is not yet ready (eg. PCRF crashed), and
a client sends a CreateSessionRequest announcing its ow F-TEID,
then open5gs-smfd answers with Create Session Response Cause=
"Remote peer not responding", but it is not setting the received F-TEID
in the header of the response, instead it sends with TEI=0.

As a result, the peer cannot match the CreateSessionResponse, and needs
to rely on its own timeout timer to figure out that specific request failed.

This also happens in PFCP, so to solve this problem, I added teid/seid_presence
to the interface that sends the error message as shown below.

void ogs_gtp2_send_error_message(ogs_gtp_xact_t *xact,
        int teid_presence, uint32_t teid, uint8_t type, uint8_t cause_value);
void ogs_pfcp_send_error_message(
    ogs_pfcp_xact_t *xact, int seid_presence, uint64_t seid, uint8_t type,
    uint8_t cause_value, uint16_t offending_ie_value);

Sukchan Lee 1dc4300203 [AMF] ran_ue can be NULL in IMPLICIT Dereg (#2999) 
When we try to send an SBI message to SMF to release a session,
sometimes ran_ue is NULL. This happens when the Mobile Reachable Timer expires
and Implicit Deregistration is triggered.

To account for this case, we added the `ran_ue` parameter to the SBI interface
and made it work even if it is NULL.

Pau Espin 3b5e851f5d [SMF] Gy: Remove 3GPP-RAT-Type AVP from Multiple-Services-Credit-Control AVP 
This AVP is optional and was added in later releases of the 3GPP TS
32.299 spec. For instance, it shows up in Release 16 (V16.2.0), but
doesn't show up in Release 12 (V12.7.0).

Some OCS, like PortaOne OCS, implement older versions of the release
(V12.14.0), and hence fail when receiving the 3GPP-RAT-Type inside
Multiple-Services-Credit-Control AVP.
Since nowadays we also send the 3GPP-RAT-Type in PS-Information AVP,
which has been specified for longer time (it already shows up in
V12.7.0), drop it from Multiple-Services-Credit-Control to have greater
compatibility with other vendors.

Pau Espin ea122da9fc [SMF] Allow Gy CCA event to contain NULL gtp_xact 
This happens for instance when the session is terminated due to a
rejection coming from the OCS, hence no originating GTP xact producing
the tear down.
 2024-03-20 07:03:18 +09:00
Pau Espin 32a275b9a8 [SMF] smf_gy_send_ccr: Allow NULL xact 
The xact may well be NULL, eg. when tearin down the session
(send_ccr_termination_req_gx_gy_s6b()) because OCS rejected an update:
Hence there's no GTP xact originating the tear down, aka e->gtp-xact
passed to the function is NULL.

smf_gx_send_ccr() is already handling this case properly, contrary to smf_gf_send_ccr().
