CVE-2023-27532: Veeam Backup & Replication Credential Theft Vulnerability
CVSSv3: 7.5
Veeam has released a patch to address a vulnerability in their Backup & Replication component. This vulnerability may be leveraged to allow an unauthenticated attacker to remotely access encrypted credentials that are stored in the configuration database and gain access to hosts and devices served by the Veeam Backup Server, providing an attacker with the ability to achieve remote code execution (RCE) on the host.
An attacker may exploit this by interrogating the local API which is listening by default on TCP port 9401.
There is a POC for this exploit available publicly and there is high potential that this will soon be leveraged by threat actors against organizations using this product.
