Lifecycle Timeline
2DescriptionCVE.org
A vulnerability allowing a high-privileged user to execute arbitrary code on the server.
AnalysisAI
Remote code execution in Veeam ONE, the enterprise backup monitoring and analytics platform, is achievable by high-privileged authenticated users via a network-accessible code injection flaw (CWE-94). The vulnerability carries a CVSS 4.0 score of 8.6 with full confidentiality, integrity, and availability impact on the vulnerable system, reported through HackerOne and detailed in Veeam KB4892. No public exploit code or CISA KEV listing has been identified at time of analysis, moderating near-term mass-exploitation risk despite the critical impact class.
Technical ContextAI
CWE-94 (Improper Control of Generation of Code) identifies the root cause: Veeam ONE fails to properly sanitize or neutralize user-controlled input before incorporating it into a code generation or evaluation context, enabling injection of executable code into the server runtime. The affected product is identified by CPE cpe:2.3:a:veeam:one:*:*:*:*:*:*:*:* - the wildcard version field indicates all releases of Veeam ONE are listed as potentially affected with no version bound specified. Veeam ONE is a monitoring, reporting, and analytics component of the Veeam Data Platform, deployed in enterprise environments to provide visibility over Veeam-managed backup and replication infrastructure. Its privileged position in backup architectures means a compromise can expose backup credentials, job configurations, and telemetry for the entire protected environment.
RemediationAI
Consult the Veeam security advisory at https://www.veeam.com/kb4892 for the official fix. A patched version number is not independently confirmed from available input data - the exact remediated release must be obtained directly from that advisory before planning upgrades. As compensating controls pending patching, restrict access to Veeam ONE's administrative and web interfaces to only explicitly authorized administrators using network-layer controls (firewall rules, VPN, or jump-host enforcement); this reduces the attacker surface but does not eliminate risk if a high-privileged account is already compromised. Audit and minimize the set of accounts holding high-privileged roles within Veeam ONE, rotating credentials for any account with recent unverified activity. Enable logging and alerting on unusual server-side execution events within the Veeam ONE host. Note that credential restriction alone does not address the underlying code injection flaw and patching remains the definitive remediation.
