Any domain user could hack backup servers!<\/h2>\n\n

A vulnerability in Veeam Backup & Replication software that allows remote code execution could allow any domain user to compromise backup servers with SYSTEM privileges.<\/p>\n\n

Are you prepared for cyber threats?<\/h2>\n\n

With modern protection mechanisms, the right strategy and managed security services such as the DEFENDERBOX<\/a>\u00a0the risk can be minimized considerably. Digital security must become a priority - because attackers are already using the latest technologies. It's time to be one step ahead of them! Protect your company!<\/p>\n\n

Safety mechanism fails<\/h2>\n\n

The vulnerability, labeled CVE-2025-23120, affects Veeam Backup & Replication 12.3.0.310 and all previous builds of version 12 and shows that blacklist-based security mechanisms continue to fail in enterprise environments.<\/p>\n\n

According to the watchTowr Labs report, the vulnerabilities exploit flawed deserialization mechanisms in Veeam's backup solution, allowing attackers to escalate privileges and potentially compromise critical backup infrastructures.<\/p>\n\n

Most worrisome is the authentication barrier: any user belonging to the \"Local Users\" group on a Windows host running Veeam, or any domain user if the server is connected to Active Directory, can exploit these vulnerabilities.Million-dollar losses and copycats<\/p>\n\n

The security flaws stem from Veeam's implementation of a blacklist-based protection mechanism for the .NET BinaryFormatter deserialization process.<\/p>\n\n

The researchers identified two different gadget chains (WT-2025-0014 and WT-2025-0015) that override these protective mechanisms.<\/p>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
