Veeam has launched safety updates to deal with a important safety flaw impacting its Backup & Replication software program that might result in distant code execution.
The vulnerability, tracked as CVE-2025-23120, carries a CVSS rating of 9.9 out of 10.0. It impacts 12.3.0.310 and all earlier model 12 builds.
“A vulnerability permitting distant code execution (RCE) by authenticated area customers,” the corporate mentioned in an advisory launched Wednesday.
Safety researcher Piotr Bazydlo of watchTowr has been credited with discovering and reporting the flaw, which has been resolved in model 12.3.1 (construct 12.3.1.1139).
In accordance with Bazydlo and researcher Sina Kheirkhah, CVE-2025-23120 stems from Veeam’s inconsistent dealing with of deserialization mechanism, inflicting an allowlisted class that may be deserialized to pave the way in which for an internal deserialization that implements a blocklist-based method to stop deserialization of information deemed dangerous by the corporate.
This additionally signifies that a menace actor might leverage a deserialization gadget lacking from the blocklist – particularly, Veeam.Backup.EsxManager.xmlFrameworkDs and Veeam.Backup.Core.BackupSummary – to realize distant code execution.
“These vulnerabilities could be exploited by any person who belongs to the native customers group on the Home windows host of your Veeam server,” the researchers mentioned. “Higher but – when you’ve got joined your server to the area, these vulnerabilities could be exploited by any area person.”
The patch launched by Veeam provides the 2 devices to the prevailing blocklist, which means the answer might as soon as once more be rendered prone to related dangers if different possible deserialization devices are found.
The event comes as IBM has shipped fixes to remediate two important bugs in its AIX working system that might allow command execution.
The checklist of shortcomings, which affect AIX variations 7.2 and seven.3, is under –
- CVE-2024-56346 (CVSS rating: 10.0) – An improper entry management vulnerability that might allow a distant attacker to execute arbitrary instructions through the AIX nimesis NIM grasp service
- CVE-2024-56347 (CVSS rating: 9.6) – An improper entry management vulnerability that might allow a distant attacker to execute arbitrary instructions through the AIX nimsh service SSL/TLS safety mechanism
Whereas there isn’t a proof that any of those important flaws have been exploited within the wild, customers are suggested to maneuver rapidly to use the required patches to safe towards potential threats.
