As part of that commitment, we operate a\u00a0[Vulnerability Disclosure Program (VDP)](https://www.veeam.com/vulnerability-disclosure.html)\u00a0for all Veeam products and perform extensive internal code audits. When a vulnerability is identified, our team promptly develops a patch to address and mitigate the risk. In line with our dedication to transparency, we publicly disclose the vulnerability and provide detailed mitigation information. This approach ensures that all potentially affected customers can quickly implement the necessary measures to safeguard their systems. It\u2019s important to note that once a vulnerability and its associated patch are disclosed, attackers will likely attempt to reverse-engineer the patch to exploit unpatched deployments of Veeam software. This reality underscores the critical importance of ensuring that all customers use the latest versions of our software and install all updates and patches without delay.\n\nIssue Details\n-------------\n\n#### **CVE-2025-48983**\n\nA vulnerability in the Mount service of Veeam Backup & Replication, which allows for remote code execution (RCE) on the Backup infrastructure hosts by an authenticated domain user.\n\n**Severity:**\u00a0Critical  \n**CVSS v3.1 Score:**\u00a09.9CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H  \n**Source:** Reported by CODE WHITE.\n\n**Note:**\u00a0The Veeam Software Appliance and upcoming Veeam Backup & Replication v13 software for Microsoft Windows are architecturally not impacted by these types of vulnerabilities.\n\n#### **CVE-2025-48984**\n\nA vulnerability allowing remote code execution (RCE) on the Backup Server by an authenticated domain user.\n\n**Severity:**\u00a0Critical  \n**CVSS v3.1 Score:** 9.9\\>CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H  \n**Source:** Reported by\u00a0Sina Kheirkhah (@SinSinology) and Piotr Bazydlo (@chudyPB) of watchTowr.\n\n**Note:**\u00a0The Veeam Software Appliance and upcoming Veeam Backup & Replication v13 software for Microsoft Windows are architecturally not impacted by these types of vulnerabilities.\n\n#### **CVE-2025-48982**\n\nThis vulnerability in Veeam Agent\u00a0_for Microsoft Windows_ allows for Local Privilege Escalation if a system administrator is tricked into restoring a malicious file.\n\n**Severity:**\u00a0High  \n**CVSS v3.1 Score:**\u00a07.3CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H  \n**Source:** Reported by an anonymous contributor working with the Trend Zero Day Initiative.\n\n##### **Affected Product**\n\nVeeam Agent\u00a0_for Microsoft Windows_\u00a06.3.2.1205 and all\u00a0[earlier version 6 builds](https://www.veeam.com/kb2683).  \n**Note:**\u00a0[Unsupported product versions](https://www.veeam.com/product-lifecycle.html)\u00a0are not tested, but are likely affected and should be considered vulnerable.  \n\n##### **Solution**\n\nThis vulnerability was fixed starting in the following build:\n\n*   [Veeam Agent\u00a0_for Microsoft Windows_ 6.3.2.1302](https://www.veeam.com/kb2683)  \n    Veeam Agent\u00a0_for Microsoft Windows_ is included with Veeam Backup & Replication and available as a standalone application.\n\nTo submit feedback regarding this article, please click this link: [Send Article Feedback](about:blank?ad=in-text-link#kb_request_form)  \nTo report a typo on this page, highlight the typo with your mouse and press CTRL + Enter.", "creation_timestamp": "2025-10-15T14:05:45.933928+00:00", "timestamp": "2025-10-27T08:47:55.784591+00:00", "related_vulnerabilities": ["CVE-2025-48984", "CVE-2025-48983", "CVE-2025-48982"], "author": {"login": "adulau", "name": "Alexandre Dulaunoy", "uuid": "c933734a-9be8-4142-889e-26e95c752803"}}
