CVE-2024-54910 identifies a permissions misconfiguration vulnerability in Hasleo Backup Suite Free version 4.9.4 and earlier. The issue lies specifically within the file recovery function, where insecure permissions allow users with high privileges to access or manipulate backup files beyond intended scope. This vulnerability is categorized under CWE-732, which involves improper permissions that can lead to unauthorized access or privilege escalation. The CVSS 3.1 vector (AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L) indicates that exploitation is possible remotely over a network, requires high privileges but no user interaction, and impacts confidentiality, integrity, and availability to a limited degree. Although no known exploits have been reported in the wild and no official patches have been released, the vulnerability poses a risk of data leakage, unauthorized modification, or disruption of backup data integrity. Backup software is a critical component in organizational data protection strategies, and improper permissions can undermine the reliability and security of backup and recovery processes. Organizations relying on Hasleo Backup Suite Free should audit and harden file permissions related to recovery functions and monitor for suspicious access patterns. Given the lack of patches, temporary mitigations such as restricting access to backup files and recovery functions to trusted administrators are essential.

The vulnerability could allow an attacker with high privileges on a networked system to access or modify backup files improperly, potentially leading to unauthorized disclosure of sensitive data, corruption of backup data, or denial of backup recovery operations. This undermines the integrity and availability of backup data, which is critical for disaster recovery and business continuity. Organizations relying on Hasleo Backup Suite Free for backup and recovery may face increased risk of data loss or compromise if this vulnerability is exploited. Although exploitation requires high privileges, the network attack vector means that compromised or insider accounts could leverage this flaw to escalate damage. The medium severity rating reflects the moderate impact and exploitation complexity, but the critical nature of backup data means the consequences could be significant in sensitive environments.

1. Immediately audit and restrict file system permissions related to the Hasleo Backup Suite Free recovery function, ensuring only trusted administrators have access. 2. Isolate backup servers and restrict network access to them, limiting exposure to potentially compromised accounts. 3. Monitor logs and access patterns for unusual or unauthorized attempts to access or modify backup files. 4. Implement strict role-based access controls (RBAC) to minimize the number of users with high privileges on systems running the backup software. 5. Until an official patch is released, consider using alternative backup solutions with verified secure permission models in high-risk environments. 6. Regularly back up critical data using multiple methods and verify backup integrity to mitigate potential damage from exploitation. 7. Stay informed about vendor updates and apply patches promptly once available.
