Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A local privilege escalation vulnerability in Acronis Cyber Protect Home Office for Windows allows an attacker to gain elevated privileges during recovery operations due to improper handling of symbolic links (soft links). The vulnerability stems from the application not properly validating symlink paths during recovery processes, potentially allowing an attacker to manipulate filesystem links to escalate from a standard user to administrator or system privileges.

MitigationUpdate Acronis Cyber Protect Home Office to build 40173 or later. Organizations should prioritize patching systems where standard users have access, as the vulnerability requires local system access to exploit.
