CVE-2025-50031 is a Missing Authorization vulnerability (CWE-862) found in the syedamirhussain91 DB Backup software, affecting versions up to 6.0. This vulnerability arises due to incorrectly configured access control mechanisms, allowing users with limited privileges (PR:L - Privileges Required: Low) to exploit the system without requiring user interaction (UI:N). The vulnerability is network exploitable (AV:N) and does not require elevated privileges beyond low-level access, making it easier for an attacker with some access to the network to leverage this flaw. The impact primarily affects confidentiality (C:H), meaning that sensitive data stored or managed by the DB Backup tool could be exposed to unauthorized users. However, integrity and availability are not impacted. The vulnerability does not require user interaction and affects the system in an unchanged security scope (S:U). The CVSS v3.1 base score is 6.5, indicating a medium severity level. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability stems from missing or insufficient authorization checks in the backup management functionality, potentially allowing an attacker to access or extract database backups without proper permissions. This could lead to exposure of sensitive database contents, including personally identifiable information (PII), intellectual property, or other confidential data stored in backups. Given the nature of backup software, unauthorized access could also facilitate further lateral movement or data exfiltration within an organization’s network.

For European organizations, the exposure of sensitive backup data due to this vulnerability could have significant consequences. Many organizations in Europe are subject to strict data protection regulations such as GDPR, which mandates the protection of personal data. Unauthorized access to database backups could result in data breaches involving personal data, leading to regulatory fines, reputational damage, and loss of customer trust. Additionally, organizations relying on syedamirhussain91 DB Backup for critical database backup and recovery operations may face risks of data leakage that could compromise business confidentiality and competitive advantage. Although the vulnerability does not affect data integrity or availability directly, the confidentiality breach alone is serious, especially for sectors handling sensitive data such as finance, healthcare, and government. The medium severity rating suggests that while the vulnerability is not trivially exploitable by unauthenticated attackers, it still poses a realistic threat if an attacker gains low-level access to the network or system. This risk is amplified in environments where network segmentation or access controls are weak.

To mitigate this vulnerability, European organizations should first verify if they are using syedamirhussain91 DB Backup software, especially versions up to 6.0. Since no official patches are currently available, organizations should implement compensating controls immediately. These include: 1) Restricting network access to the DB Backup management interfaces to trusted administrators only, using firewalls and network segmentation. 2) Enforcing strict access control policies and monitoring user privileges to ensure only authorized personnel have access to backup functions. 3) Implementing multi-factor authentication (MFA) for all users accessing backup management interfaces to reduce risk from compromised credentials. 4) Conducting regular audits and monitoring of backup access logs to detect unauthorized access attempts promptly. 5) If possible, isolating backup systems from general user networks to minimize exposure. 6) Preparing incident response plans specifically for backup data breaches. Organizations should also maintain contact with the vendor or security advisories to apply patches or updates once available. Finally, encrypting backup data at rest and in transit can reduce the impact of unauthorized access.
