CVE-2025-53246 is a missing authorization vulnerability identified in the Backup and Move software developed by Gaurav Aggarwal, affecting versions up to and including 0.1. The flaw arises from incorrectly configured access control security levels, allowing an attacker with low privileges (PR:L) to exploit the system remotely (AV:N) without requiring user interaction (UI:N). The vulnerability impacts the confidentiality, integrity, and availability of backup data, as unauthorized users can potentially access, modify, or delete critical backup files. The CVSS v3.1 base score of 8.8 reflects the high severity, emphasizing the ease of exploitation due to low attack complexity (AC:L) and the broad impact scope (S:U). Although no public exploits have been reported yet, the vulnerability's nature suggests that attackers could leverage it to compromise backup data, leading to data loss or ransomware scenarios. Backup and Move is a backup management tool, and its compromise could disrupt data recovery processes, affecting business continuity. The vulnerability was reserved in June 2025 and published in November 2025, but no patches or mitigations have been officially released at the time of this report. The lack of patches increases the urgency for organizations to implement compensating controls and monitor for suspicious activities related to backup operations.

For European organizations, the impact of CVE-2025-53246 can be severe, especially for those relying on Backup and Move for critical data backup and recovery. Unauthorized access to backup data can lead to exposure of sensitive information, violating data protection regulations such as GDPR. Integrity compromise could result in corrupted backups, undermining disaster recovery efforts and potentially causing extended downtime. Availability impacts may disrupt business operations, particularly in sectors like finance, healthcare, and government where data availability is crucial. The ability to exploit this vulnerability remotely without user interaction increases the risk of widespread attacks. Organizations with inadequate network segmentation or weak internal access controls are particularly vulnerable. The threat also poses risks to supply chain security if backup data includes sensitive vendor or partner information. Overall, the vulnerability threatens confidentiality, integrity, and availability, potentially leading to financial losses, reputational damage, and regulatory penalties within Europe.

1. Immediately restrict network access to Backup and Move management interfaces to trusted IPs only, using firewalls or network segmentation. 2. Enforce strict role-based access controls (RBAC) and the principle of least privilege for all users interacting with backup systems. 3. Monitor logs and audit trails for unusual access patterns or unauthorized backup operations. 4. Implement multi-factor authentication (MFA) for all administrative access to backup software. 5. Until an official patch is released, consider isolating backup servers from general network access and limit backup data exposure. 6. Regularly back up backup configurations and data to an offline or immutable storage to prevent tampering. 7. Conduct internal penetration testing focused on backup systems to identify potential exploitation paths. 8. Stay informed on vendor updates and apply patches promptly once available. 9. Educate IT staff on the risks of missing authorization vulnerabilities and the importance of access control hygiene. 10. Integrate backup system monitoring into broader security information and event management (SIEM) solutions for real-time alerting.
