Lifecycle Timeline
2DescriptionCVE.org
A vulnerability allowing remote unauthenticated code execution on the agent host.
AnalysisAI
Remote unauthenticated code execution in Veeam ONE (CPE cpe:2.3:a:veeam:one) allows attackers to run arbitrary code on the agent host over the network with no credentials or user interaction. The flaw is a CWE-94 code injection carrying a maximal CVSS 4.0 base score of 10.0, reflecting full compromise of both the vulnerable and downstream systems. Reported via HackerOne with a Veeam KB advisory published; no public exploit has been identified at time of analysis.
Technical ContextAI
Veeam ONE is the monitoring, reporting, and analytics component of the Veeam Data Platform, used to oversee backup infrastructure, virtualization hosts, and agents. The affected element is the 'agent host' referenced in the description, indicating the injection is reachable through the agent/monitoring communication surface. The root cause is classified as CWE-94 (Improper Control of Generation of Code, i.e. code injection), meaning attacker-controlled input reaches a code interpreter or evaluation path and is executed rather than treated as inert data. The CPE cpe:2.3:a:veeam:one:*:*:*:*:*:*:*:* scopes this to the Veeam ONE application across unspecified versions.
RemediationAI
Apply the fix described in the Veeam advisory at https://www.veeam.com/kb4892; Patch available per vendor advisory, though an exact patched version number was not included in the available data and must be confirmed from that KB before deployment. Because exploitation is remote and unauthenticated against the agent/monitoring surface, if immediate patching is not possible restrict network reachability to the Veeam ONE server and its agent communication ports to trusted management networks or a jump host, and monitor the agent host for anomalous process execution - with the trade-off that network restrictions may disrupt legitimate agent data collection and remote console access. Do not rely on authentication controls as a mitigation since PR:N confirms none is required.
