Hi,

On FortiSIEM 7.3.2, I cannot create an SNMPv3 credential, I always get the following error: Save failed - invalid characters (`, $, >, <, &, ;, |) found

Has anyone encountered this error? What could be the problem?

Thanks,

Zoltan

Hi Zoltan

Can you share the full command you are using?

Trying to do the same on FSM 7.2.5 and it works fine.

Yes, it worked for me with the previous version too. Not on 7.3.2

I don't find such known bug in release notes. Then you probably discovered a new bug in 7.3.2.

I suggest to open a ticket so Fortinet can fix it in the next patch, and they may provide you a workaround meanwhile.

Hi @rz5 ,

I think that the message is pretty clear. Do you use any following special characters in your password?

(`, $, >, <, &, ;, |)

I tried them in password and they are accepted.

on fortisiem 7.3.2?

No, I mean FSM 7.2.5.

BTW that's why you should always install mature releases in your production env.

I'm experiencing the same issue on FortiSIEM 7.3.2.0374 — trying to save an SNMPv3 access method throws a "Save failed - invalid characters" error even when using clean and valid values without any special characters. I've tested with multiple browsers, different keyboard layouts, and manually typed inputs, but the validation still fails. This appears to be a frontend validation bug in the SNMPv3 config form. You're not alone — hope Fortinet patches this soon.
