CVE-2020-9452 describes a local privilege escalation vulnerability in Acronis True Image 2020 (version 24.5.22510). An unprivileged user can exploit a flaw in the anti-ransomware service's quarantine function, which uses SYSTEM privileges to copy files, by leveraging hardlinks to achieve arbitrary file write/overwrite capabilities. This allows for trivial escalation to SYSTEM privileges. Rated with a CVSS score of 7.8 (High), the vulnerability has a low attack complexity and requires only low privileges, but can lead to high impact on confidentiality, integrity, and availability. The attack vector is local, meaning an attacker needs prior access to the system. Currently, there is no public exploit code available (Metasploit, Nuclei, ExploitDB), nor is it listed in the CISA KEV catalog, indicating it is not actively exploited. Community discussion and media coverage are minimal, suggesting low public awareness.
