CVE-2024-42019
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability that allows an attacker to access the NTLM hash of the Veeam Reporter Service service account. This attack requires user interaction and data collected from Veeam Backup & Replication.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is a credential disclosure vulnerability in Veeam Backup & Replication that allows an attacker to obtain the NTLM hash of the Veeam Reporter Service service account. The attack requires user interaction and prior data collection from the Veeam environment, suggesting it may involve some form of induced authentication or relay attack.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed Veeam One versionOpen Veeam One Client or navigate to the installation directory and locate the version information, typically found in 'C:\Program Files\Veeam\One\VeeamOneMonitor.exe' properties or via Add/Remove ProgramsAffected if Version is lower than 12.2.0.4093
-
Verify Reporter Service statusOpen Windows Services (services.msc) and locate the 'Veeam Reporter Service' or check via PowerShell: Get-Service -Name 'VeeamReporterSvc' 2>$null or similar named serviceAffected if Reporter Service exists and is running on the system
-
Check Reporter Service network listenersRun 'netstat -an | findstr LISTENING' and look for ports associated with Reporter Service (commonly port 8080, 8443, or configured web service ports), or review Veeam configuration files in 'C:\Program Files\Veeam\One\Reporter\'Affected if Reporter Service is listening on network-accessible ports without proper restriction
-
Review Windows Security event logs for NTLM authentication anomaliesOpen Event Viewer, navigate to Windows Security logs, filter for Event ID 4624 (successful logon) or 4648 (explicit credential logon) where the target account is the Veeam service account and source is unexpectedAffected if Authentication events show the service account authenticating to untrusted or external systems without legitimate cause
-
Check for configured service account reuseQuery Active Directory for the Veeam Reporter Service account (typically found in Veeam configuration database or registry under HKLM\SOFTWARE\Veeam\Veeam One\) and verify if that account has unnecessary privileges or SPNsAffected if Service account has excessive privileges or is used across multiple high-value systems
You are affected if Veeam One version is below 12.2.0.4093 and the Reporter Service is actively running and exposed on the network.
