Authenticated Cloud Connect tenants can read arbitrary files on the Veeam Backup & Replication service provider host through a path traversal flaw (CWE-22). This affects service providers that deploy the Cloud Connect feature and serve tenants; standalone installations without Cloud Connect are not reachable via this tenant path. The attack is network-reachable and low-complexity with no user interaction, but impact is limited to read-only disclosure and no public exploit code or confirmed active exploitation has been identified at time of analysis. This is a credible, above-average priority for Veeam Cloud Connect service providers, though not a drop-everything emergency on current signals.
Local privilege escalation in the Veeam Updater component of the Veeam Software Appliance allows a high-privileged local user to reach root-level control of the underlying operating system via path traversal (CWE-22). The flaw affects Veeam Backup & Replication deployed as the hardened software appliance, carries a CVSS 4.0 base score of 8.4, and was reported through HackerOne. No public exploit has been identified at time of analysis and it is not listed in CISA KEV, so current risk is latent rather than actively exploited.
Remote code execution in Veeam Backup & Replication enables an authenticated domain user to execute arbitrary code on the Backup Server, with CVSS 4.0 score of 9.4 reflecting high impact across confidentiality, integrity, and availability of both the vulnerable component and downstream systems. The vulnerability is tagged as a deserialization flaw (CWE-502), and while no public exploit is identified at time of analysis, the low attack complexity and only-low-privilege requirement make this a high-priority patching event for any environment running Veeam in a domain-joined configuration.
Arbitrary file write in Veeam Backup & Replication 13 (≤13.0.1) on Linux-based deployments allows an authenticated Backup Administrator to write files anywhere on the server filesystem, enabling code execution and full host compromise. CVSS 4.0 scores this 8.6 (High) due to network-reachable exploitation with high impact across confidentiality, integrity, and availability, though high privileges are required. No public exploit identified at time of analysis.
Local privilege escalation in Veeam Agent for Microsoft Windows enables a low-privileged authenticated user to escalate to higher privileges on the host, with the CWE-532 mapping indicating sensitive information is exposed via log files that the attacker can read or abuse. CVSS 4.0 base score is 7.3 with high impact to confidentiality, integrity, and availability of the vulnerable component, and no public exploit identified at time of analysis. The flaw is tied to the broader Veeam Backup and Replication 13 ecosystem (≤13.0.1 per ENISA EUVD), making it relevant on any Windows endpoint where the Veeam Agent is deployed alongside or as part of that platform.
Authenticated Backup Viewer accounts in Veeam Backup & Replication can modify the Enterprise Manager master key and stored antivirus-update credentials due to missing authorization (CWE-862), affecting deployments with Enterprise Manager and that low-privilege role. The issue is medium severity (CVSS 4.0 score 6.1) and requires valid Backup Viewer credentials plus an additional attack precondition, so it is not anonymous or unauthenticated exploitation; no public exploit identified at time of analysis. Veeam KB4934 is the referenced advisory for affected and fixed builds.
Authenticated users holding only the low-privileged 'Backup Viewer' role on Veeam Backup & Replication can leverage a deserialization flaw to execute arbitrary code as SYSTEM on the backup server, turning a read-only backup monitoring account into full control of the backup infrastructure (CVSS 9.4; CWE-502). The attack is network-reachable (AV:N) and requires no user interaction, but it is not unauthenticated: a valid Backup Viewer account or stolen credentials for that role are mandatory (PR:L), which realistically limits exposure to insiders, credential-theft scenarios, or attackers who have already chained into the environment. The high severity is compounded by the scope change (S:C) and full loss of confidentiality, integrity, and availability across the backup server and connected systems; no public exploit code or confirmed active exploitation was identified at time of analysis.
Credential exposure in Veeam Backup & Replication occurs when guest OS processing operations write privileged account credentials to a support log file in cleartext, leaving them recoverable by any local user with read permissions on that log. Documented via HackerOne and Veeam KB4902, this CWE-532 information disclosure flaw affects all tracked versions per CPE data. No public exploit code has been identified at time of analysis, and the vulnerability does not appear in the CISA KEV catalog.
Bypass of Windows Driver Signature Enforcement in Veeam Backup and Replication 12.x and Software Appliance 13.x allows local administrators to load unsigned kernel drivers, potentially enabling persistent kernel-level compromise. The vulnerability requires high-level administrative privileges and is not actively exploited in the wild; however, EPSS scoring (0.01%) suggests this is a low-probability exploitation target despite the high CVSS score, indicating the attack scenario is constrained by strict privilege and configuration requirements.
