Upgraded JRE Version for Synthetic ActiveGate

sivart_89 — Thu, 02 Nov 2023 11:54:51 GMT

Our ActiveGates were flagged in a vulnerability report for having an outdated JRE version in both /opt/dynatrace/gateway/jre/bin (version 11.0.19) and /opt/dynatrace/synthetic/jre/bin (version 17.0.7). The upgrade to version 1.227 for our ActiveGates fixed things for /opt/dynatrace/gateway/jre/bin (release notes below) but I am still seeing version 17.0.7 in /opt/dynatrace/synthetic/jre/bin.

How can we update the JRE in the synthetic directory for our synthetic ActiveGates?

Hi @sivart_89

You do not have the option to manually update the Java version for ActiveGate. The answer I got once from support:
You can't do that on your own. We need to deliver java with our code. Good news is that we are going upgrade java to 8u202 in v168.

I recommend you to create a ticket in support.

Hi @sivart_89,

I had the same issue. I have just received an answer from support.

"We will update the Java to 17.0.9 in ActiveGate 1.281. Expected release date is mid of January."

Best regards,

Mizső

Hi @Mizső thanks for the information here. I forgot to follow up with this one. I ended up creating a support ticket for this on 11/2. Support told me this will be in place late November with AG 1.279. We are on SaaS though so I wonder if that is the difference with what you were told? Hopefully we are still on track for 1.279

Hi @Suryanto_1,

I am gonig to check it after the managed 1.282 roll out at the 1.281 AG.

Best regards,

Mizső

Also is the rollout correct. We are getting AG 1.282 instead of 1.281.

The installer we downloaded is ActiveGate 1.282.18.20240111-043946

As in cluster server are even number while ActiveGate are odd number.

Another thing to point out from the AG 1.281 release note

RHEL 8.9 is supported on the server but not on the ActiveGate

I'm checking on the AG version. You're correct I wouldn't expect 1.282 to be available in Production.

Suryanto_1 — Fri, 19 Jan 2024 02:14:46 GMT

Does the upcoming 1.283 support RHEL 8.9 and fix the JRE vulnerability?

Re: Upgraded JRE Version for Synthetic ActiveGate

HannahM — Tue, 23 Jan 2024 16:12:24 GMT

I can't see any plans for the Synthetic AG to be supported in RHEL 8.9.

Hi @Suryanto_1 ,

Original java issue has been solved in AG. Synthetic jre upgarde has been done from 17.0.7 to 17.0.8

Thats good to know. However

1. Release note didnt state it was taken care of (which usually an evidence for customers)

2. When I log case with support they also mention say fix in the upcoming AG 11.283 release with JRE 17.0.9

Hopefully info can be better in sync to reduce confusion and inconvenience

Re: Upgraded JRE Version for Synthetic ActiveGate

Suryanto_1 — Thu, 25 Jan 2024 09:19:28 GMT

Support says it would be latest support by AG 11.285 release sometime in March

Interesting. I can see that should be the case for a vanilla ActiveGate but I thought you were interested in Synthetic. For Synthetic, I can't see this being worked on. I only see this for standard AG.
