Published Jan 27, 2026 CVSS 3.0 · 6.7 Medium EPSS < 1% KEV · Not listed

Description

Local privilege escalation due to insecure folder permissions. The following products are affected: Acronis Cloud Manager (Windows) before build 6.4.25342.354.

Analysis

Technical impact

The vulnerability arises from insecure folder permissions in Acronis Cloud Manager, allowing an attacker with local access to modify critical directories. This can lead to escalation of privileges and compromise the integrity of the system. The flaw is categorized as CWE-276, indicating improper configuration of permissions.

Affected Systems

Acronis Cloud Manager (Windows) versions prior to build 6.4.25342.354 are affected.

Risk and Exploitability

The CVSS score of 6.7 denotes a medium severity vulnerability. With an EPSS score of less than 1% and no listing in the CISA KEV catalog, the likelihood of exploitation is low at present. However, the attack requires local user access and can result in full administrative control over the compromised host. The attack vector is inferred to be local due to the nature of the permission issue and the lack of remote interfaces mentioned in the description.
