CVE-2024-42453: A vulnerability Veeam Backup & Replication allows low-privileged users to control and modify configurations on connected virtual infrastruct

Noroxi assessment

Priority: Monitor (action score 32/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.33% (FIRST EPSS).
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

A vulnerability Veeam Backup & Replication allows low-privileged users to control and modify configurations on connected virtual infrastructure hosts. This includes the ability to power off virtual machines, delete files in storage, and make configuration changes, potentially leading to Denial of Service (DoS) and data integrity issues. The vulnerability is caused by improper permission checks in methods accessed via management services.
