GlobalProtect version 3 certificate

L2 Linker

Dear Team, 

 

Among models using Android 13, kernel 5.4 or 5.15, a certificate error appears to occur when connecting to the GP.

 

I confirmed with TAC that I need to use version 3 certificate.

 

However, many customers are using Paloalto's own CA certificate.

 

Is there a way to create a v3 certificate in Paloalto?

Previously, customers could use GP with only a root certificate.

 

However, due to the latest security patch in Android, GlobalProtect can no longer be used as a root certificate.

So please refer to the information below:

 

- Symptom: Unable to access GP on some Android 13 models

- Cause: It is expected that certificate-related security policies have been strengthened and changed on the Android side.

- Solution: When creating a Paloalto certificate, separate the root cert and server cert according to the recommended guide.

I believe default setting is to generate v3 certificate.

Here is my test result with PAN-OS 9.1.12

After export this cert, check with openssl command:

====

user@dom:~$ openssl x509 -text -noout -in ./cert_testcert.crt

@emr_1 Thank you for your reply

 

A number of customers are experiencing the symptom now, and i have checked the certificate based on the information you provided.

 

All certificates verified as version3.

 

Therefore, I believe there is another cause for this problem.

 

If there is any further confirmation, I will update this ticket.
