Veeam released security updates for multiple products, led by a critical authentication bypass in Veeam Backup Enterprise Manager tracked as CVE-2024-29849. The flaw allows an unauthenticated attacker to log in as any user, including an administrator, by supplying a forged VMware SSO token to the REST API service on TCP port 9398. Veeam also addressed related Enterprise Manager issues including CVE-2024-29850, which can enable account takeover through NTLM relay, CVE-2024-29851, which can expose the NTLM hash of the Enterprise Manager service account, and CVE-2024-29852.
The updates extend beyond Enterprise Manager. Veeam patched Backup & Replication, Veeam Agent for Windows, and Veeam Service Provider Console, including CVE-2024-29212, a critical remote code execution flaw in Service Provider Console, and CVE-2024-29853, a local privilege escalation issue in Agent for Windows. Veeam advised organizations to upgrade immediately, including moving Backup & Replication to at least 12.1.2.172 and Veeam Agent for Windows to at least 6.1.2; where Enterprise Manager cannot be patched promptly, the company recommended stopping the Backup Enterprise Manager service as a temporary mitigation.

Veeam released security updates for multiple products, including **Backup & Replication**, **Service Provider Console**, **Veeam ONE**, **Agent for Linux**, and several backup plug-ins, to fix a set of critical and high-severity vulnerabilities. The most severe issue, **`CVE-2024-40711`**, is a critical unauthenticated remote code execution flaw in **Veeam Backup & Replication** with a **CVSS 9.8** rating, allowing attackers to potentially compromise backup servers without logging in. The broader patch set also addresses weaknesses that could enable credential theft, backup manipulation, MFA bypass, privilege escalation, SSRF exploitation, and additional remote code execution in other Veeam components. Security advisories urged organizations to upgrade immediately to fixed versions, warning that backup infrastructure is a high-value target and that successful exploitation could materially increase ransomware risk by giving attackers access to recovery systems.

Veeam released security updates for multiple products after disclosing several vulnerabilities that affect enterprise backup and monitoring environments, including **Veeam Backup & Replication**, **Veeam ONE**, and **Veeam Service Provider Console**. The most severe issue, **`CVE-2026-32998`**, is a critical remote code execution flaw in Veeam Service Provider Console with a **CVSS score of 9.4**; Veeam said it is fixed in **version `9.2.1.33875`**. Canadian Centre for Cyber Security advisory **AV26-513** said affected versions include Veeam Backup & Replication 13 releases before **`13.0.2.29`**, Veeam ONE releases before **`13.0.2.6723`**, and Veeam Service Provider Console 9.2 releases before **`9.2.1.33875`**, and urged administrators to apply the vendor updates. Veeam also patched **`CVE-2026-32996`**, a high-severity local privilege escalation flaw in **Veeam Agent for Microsoft Windows** that could let a low-privileged local user gain administrative control, and **`CVE-2026-32997`**, an arbitrary file write issue affecting Linux-based backup servers running the **Veeam Software Appliance** that could allow an authenticated backup administrator to modify system files. For organizations unable to patch immediately, Veeam provided a workaround for the Service Provider Console bug by disabling the `AlarmManagement_ScriptExecution` setting in the local configuration JSON file, while older reporting on **Veeam ONE** underscores the continued security focus on Veeam’s management stack.

**Veeam** released security updates for **Backup & Replication** to address multiple high-severity flaws, including several **remote code execution** issues affecting version `12.3.2.4165` and all earlier version 12 builds. The disclosed vulnerabilities include `CVE-2026-21666`, `CVE-2026-21667`, `CVE-2026-21668`, `CVE-2026-21672`, and `CVE-2026-21708`, with several carrying **CVSS 9.9** ratings. According to the advisories, successful exploitation could allow authenticated domain users to execute code on the backup server, manipulate arbitrary files on a backup repository, or achieve local privilege escalation on Windows-based servers. Veeam said the issues were fixed in **Backup & Replication** version `12.3.2.4465`, while `CVE-2026-21672` and `CVE-2026-21708` were also remediated in version `13.0.1.2067`, alongside additional critical flaws `CVE-2026-21669` and `CVE-2026-21671`. The company warned that public patch disclosure increases the likelihood of **patch reverse engineering** and follow-on attacks against unpatched systems, making rapid remediation a priority for organizations running exposed or domain-connected Veeam infrastructure.
