Technical details of the vulnerability in Veeam Backup 🔐

The vulnerability lies in the handling of authentication requests by the Veeam.Backup.Service.exe service. An attacker with valid domain credentials can send crafted packets to TCP port 9401. This causes insecure deserialization of data, allowing the execution of arbitrary commands on the server. The flaw affects versions 12.1 and earlier. Veeam has released a security update that fixes the issue.

The paradox of the backup that leaves you without a safety net ⚠️

It turns out that the tool designed to save your data can now be used to hijack it. It's like hiring a security guard and discovering they have a copy of your keys. If you're in the domain, you don't need to be a black hat hacker; just having access and a desire to cause chaos is enough. The saddest part is that the backup system becomes the entry point for an attack.
