Official description
A series of related high-severity vulnerabilities, the most notable enabling remote code execution (RCE) as the service account and extraction of sensitive information (savedcredentials and passwords). Exploiting these vulnerabilities requires a user who has been assigned a low-privileged role within Veeam Backup & Replication.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Insufficiently Protected Credentials
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
How developers prevent this class of flaw
- Use an appropriate security mechanism to protect the credentials.
- Make appropriate use of cryptography to protect the credentials.
- Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
