CVE-2025-53246 is a missing authorization vulnerability identified in the Backup and Move software developed by Gaurav Aggarwal, affecting versions up to 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 confidentiality, integrity, and availability (C:H/I:H/A:H), indicating that an attacker could access sensitive backup data, modify or delete backups, or disrupt backup operations entirely. The vulnerability is classified as high severity with a CVSS 3.1 base score of 8.8, reflecting its critical nature. Although no known exploits are currently reported in the wild, the potential for exploitation is significant due to the low attack complexity and lack of required user interaction. The vulnerability's root cause is the absence or misconfiguration of authorization checks within the Backup and Move application, which should enforce strict access controls to prevent unauthorized actions. This flaw can be exploited remotely over the network, making it a serious threat to any organization using this software for backup management. The lack of available patches at the time of publication necessitates immediate interim mitigations to reduce exposure. Organizations should audit their deployment of Backup and Move, restrict network access to the backup system, and monitor for suspicious activity until a patch is released.

For European organizations, the impact of CVE-2025-53246 could be severe, especially for those in sectors that rely heavily on backup integrity and confidentiality such as finance, healthcare, government, and critical infrastructure. Unauthorized access to backup data could lead to exposure of sensitive personal and corporate information, violating GDPR and other data protection regulations. Integrity compromise could result in corrupted or manipulated backups, undermining disaster recovery efforts and potentially causing extended downtime or data loss. Availability disruption could halt backup operations, increasing the risk of data loss during incidents. The remote exploitability and low privilege requirement increase the likelihood of exploitation, potentially enabling lateral movement within networks. Organizations with centralized backup systems using Backup and Move are particularly vulnerable, as a single exploited instance could compromise multiple systems. The absence of known exploits currently provides a window for proactive defense, but the high CVSS score signals urgent need for mitigation to avoid significant operational and reputational damage.

1. Immediately audit all instances of Backup and Move within the organization to identify affected versions. 2. Restrict network access to Backup and Move services using firewalls and network segmentation to limit exposure to trusted administrators only. 3. Enforce strict role-based access controls (RBAC) and review user privileges to ensure minimal necessary permissions are granted. 4. Monitor logs and network traffic for unusual access patterns or unauthorized attempts to interact with the backup system. 5. Implement multi-factor authentication (MFA) for all administrative access to backup systems to reduce risk of credential compromise. 6. Prepare to apply vendor patches as soon as they become available; subscribe to vendor and CVE databases for updates. 7. Consider temporary compensating controls such as disabling remote access to the backup system if feasible. 8. Conduct regular backups verification and integrity checks to detect any unauthorized modifications early. 9. Educate IT and security teams about this vulnerability and the importance of rapid response. 10. Engage with vendors or security communities for any emerging exploit information or mitigation tools.
