CVE-2025-24826 is a local privilege escalation vulnerability identified in Acronis Snap Deploy for Windows, affecting versions prior to build 4625. The root cause is insecure folder permissions (classified under CWE-276: Incorrect Default Permissions), which allow a user with limited privileges to manipulate or replace files or directories that should be protected. This improper permission configuration can be exploited by a local attacker to gain elevated privileges on the affected system. The vulnerability requires local access and user interaction, with a high attack complexity, indicating that exploitation is not trivial but feasible under certain conditions. The CVSS 3.0 vector (AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H) reflects that the attacker must have local access, the attack complexity is high, privileges required are low, user interaction is required, and the impact on confidentiality, integrity, and availability is high. Although no public exploits have been reported, the vulnerability poses a significant risk in environments where Acronis Snap Deploy is used for system deployment and management. The lack of a patch link suggests that a fix may be forthcoming or in progress. Organizations relying on this product should be aware of the potential for privilege escalation attacks that could lead to full system compromise.

If successfully exploited, this vulnerability allows an attacker with limited local access to escalate privileges, potentially gaining administrative or SYSTEM-level control over the affected machine. This can lead to unauthorized access to sensitive data, modification or deletion of critical system files, and disruption of system availability. In enterprise environments, especially those using Acronis Snap Deploy for mass deployment or system recovery, such an escalation could compromise multiple systems or the deployment infrastructure itself. The impact extends to confidentiality, integrity, and availability, making it a serious concern for organizations that depend on secure and reliable deployment tools. The requirement for local access and user interaction limits remote exploitation but does not eliminate risk in environments with multiple users or where attackers can gain initial footholds through other means. The absence of known exploits in the wild reduces immediate risk but does not preclude future exploitation once details become widely known.

Organizations should immediately review and tighten folder permissions related to Acronis Snap Deploy installations, ensuring that only authorized users and system processes have write or modify access. Until an official patch is released, consider restricting local user access on systems running Acronis Snap Deploy to trusted administrators only. Implement monitoring and alerting for unusual file modifications or privilege escalation attempts on affected systems. Employ application whitelisting and endpoint protection solutions that can detect or block unauthorized changes to deployment tool directories. Regularly audit user permissions and system logs to identify potential exploitation attempts. Once a patch or update is available from Acronis, prioritize its deployment across all affected systems. Additionally, educate users about the risks of local privilege escalation and enforce the principle of least privilege to minimize the attack surface.
