Saw this in the Vanguard slack channel.  Need to check with Support to ensure it will not mess up other patches I have installed for various fixes.  Thanks for sharing.

I can see that 3 hotfixes are available.

If you have any new information with support, just let us know!

Yes, for different versions of VONE.  I am checking on the v12 patch with my current deployment and hotfixes.  Will update here if needed.

@wolff.mateus thanks for sharing.

@Chris.Childerhose the KB4508 is included different versions, waiting for your update if you have new information.

Waiting for Chris answer doesn‘t make much sense.
Each environment may have other privat hotfixes. The answer Chris will get is specific for his environment and not yours :)

If you know about private hotfixes in your VeeamOne server, then please open your own support case to check if the new patch interferes with it.

Best,

Fabian

@Mildur Agree.
Everyone should install Hotfix ASAP. I still encourage everyone to share his experiences in the community because vulnerabilities is not easy to find. That's why everyone joins this community help others and yourself

Yes while the patch does not affect my hotfixes everyone needs to check with support on their own hotfixes.

Just so everyone is aware I applied the hotfix for the CVE stuff which does not affect my other hotfixes implemented but having issues now.

Might need to roll it back but working with my case via support.  Warning messages during data collection task now that point to the CVE hotfix -

11/7/2023 1:00:04 PM warning]: servername: Method not found: 'System.String Veeam.Reporter.GrpcService.GrpcServices.GrpcAuthInterceptor.get_CurrentAccessJwt()'.

Be careful when applying the fix and watch your collections for this warning.

Great post, why didn’t you create a new blogpost out of this?

Because they have already made a guide in cyber security @Michael Melter 

I saw that afterwards! That was an excellent piece  ... 

I assume this only applies to the server and not to the any workstations running the Veeam One Client only.

Windows Defender detected the Veeam One Client installed on my workstation so I am wondering if I should uninstall it?

Yes this is the server side patch.
