CVE-2025-61228 is a vulnerability identified in Shirt Pocket SuperDuper! backup software versions 3.10 and earlier. The issue allows a local attacker with low privileges to execute arbitrary code through the software's update mechanism. This vulnerability is categorized under CWE-494, indicating that the software downloads and executes code without proper integrity verification, such as missing cryptographic signature checks or insufficient validation of update packages. Because the attack vector is local, the attacker must have some level of access to the system, but no user interaction is required to trigger the exploit once local access is obtained. The CVSS v3.1 base score is 7.8, reflecting high severity due to the combined impact on confidentiality, integrity, and availability (all rated high), low attack complexity, and low privileges required. The vulnerability could allow an attacker to escalate privileges or implant persistent malicious code by hijacking the update process, which typically runs with elevated permissions. No known exploits are currently in the wild, and no patches have been published at the time of disclosure, increasing the urgency for organizations to implement interim mitigations. The lack of patch availability means organizations must rely on access controls and monitoring to reduce risk. This vulnerability is particularly critical in environments where SuperDuper! is used for backup and recovery, as compromise could lead to data theft, destruction, or ransomware deployment.

For European organizations, the impact of CVE-2025-61228 is significant due to the potential for local attackers to gain arbitrary code execution with elevated privileges. This could lead to full system compromise, data breaches, and disruption of backup and recovery operations, which are critical for business continuity and compliance with data protection regulations such as GDPR. Organizations relying on SuperDuper! for backup on macOS systems may face risks of data integrity loss or ransomware attacks if the update mechanism is exploited. The vulnerability could facilitate lateral movement within corporate networks if attackers leverage compromised endpoints as footholds. Additionally, the absence of patches increases exposure time, raising the likelihood of exploitation attempts. The confidentiality of sensitive personal or corporate data could be severely impacted, potentially resulting in regulatory fines and reputational damage. Availability of backup services may also be compromised, affecting disaster recovery capabilities.

Until an official patch is released, European organizations should implement strict local access controls to limit the number of users with permissions to execute or modify the SuperDuper! update process. Employ application whitelisting and endpoint detection and response (EDR) solutions to monitor and block unauthorized code execution related to the update mechanism. Regularly audit and restrict local user privileges, ensuring that only trusted administrators have access to systems running SuperDuper!. Network segmentation can help contain potential lateral movement from compromised endpoints. Organizations should also monitor system logs and update process activities for anomalies indicative of exploitation attempts. Backup critical data using alternative methods or software where feasible to reduce reliance on the vulnerable update mechanism. Once patches become available from Shirt Pocket, prioritize immediate deployment. Additionally, educate users about the risks of local privilege escalation and enforce strong physical and logical security controls to prevent unauthorized local access.
