Due to the following questions below, I have decided to create an article to show the steps on how to patch Veeam Backup and replication from build 12.3.2.3617 to 12.3.2.4165.
- installing latest ISO patch Backup and Replication | Veeam Community Resource Hub
- Veeam Multiple Vulnerabilites CVE-2025-48983, CVE-2025-48984, CVE-2025-48982 | Veeam Community Resource Hub
To summarize the steps, you first have to determine the installed build. This can be found in the Veeam Backup & Replication Console’s Main Menu (≡) under Help > About as shown below.
I am already running on Build 12.3.2.3617.
This patch is available as an ISO or EXE. The EXE is intended ONLY for patching existing deployments of Veeam Backup & Replication 12.3.2 (build 12.3.2.3617). When you try the ISO in this case, you will be prompted to modify or uninstall your existing installation of Veeam Backup and Replication which is a dangerous thing to do. Also, you can use the ISO for new deployments of Veeam Backup & Replication 12.3.2.4165.

Veeam Component Update
After the main update is installed, Veeam runs a Component Update process to ensure that all associated components across the environment are brought to the same version as the updated backup server.
During this phase, Veeam automatically detects connected components such as backup proxies, repository servers, WAN accelerators, and transport services and updates them to match the newly installed build.
