CVE-2025-30480 is a medium-severity vulnerability identified in Dell PowerProtect Data Manager, a data protection and backup management solution widely used by enterprises for data backup, recovery, and lifecycle management. The vulnerability stems from improper input validation (CWE-20) within the software, allowing a low-privileged attacker with remote access to potentially read arbitrary files on the affected system. This flaw does not require user interaction and can be exploited remotely with low attack complexity, but it does require the attacker to have some level of authenticated access (low privilege). The vulnerability impacts confidentiality by exposing sensitive files, but does not affect integrity or availability. The CVSS 3.1 base score is 6.5, reflecting the moderate risk due to the ability to access sensitive data without elevated privileges or user interaction. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that organizations should prioritize monitoring and mitigation efforts. The vulnerability affects versions prior to 19.19 of PowerProtect Data Manager, though exact affected versions are unspecified. Given the nature of the product, the vulnerability could be leveraged to access backup data or configuration files, potentially exposing sensitive corporate or customer information.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on Dell PowerProtect Data Manager for critical data backup and recovery operations. Unauthorized access to arbitrary files could lead to exposure of sensitive personal data protected under GDPR, intellectual property, or confidential business information. This could result in regulatory penalties, reputational damage, and loss of customer trust. Additionally, attackers could use the information gained to facilitate further attacks, such as lateral movement or privilege escalation within the network. The impact is heightened for sectors with stringent data protection requirements, such as finance, healthcare, and government entities. Since the vulnerability does not impact system availability or integrity directly, the immediate operational disruption may be limited, but the confidentiality breach risk remains substantial.

European organizations should implement the following specific mitigations: 1) Immediately verify the version of Dell PowerProtect Data Manager in use and plan for an upgrade to version 19.19 or later once available. 2) Until patches are released, restrict remote access to the PowerProtect Data Manager management interfaces to trusted networks and VPNs only, minimizing exposure to potential attackers. 3) Enforce strict access controls and monitor authentication logs for unusual low-privilege access attempts. 4) Implement network segmentation to isolate backup management systems from general user networks. 5) Employ file integrity monitoring on backup servers to detect unauthorized file access or changes. 6) Regularly audit backup data and configuration files for signs of compromise. 7) Engage with Dell support for any available workarounds or interim fixes. 8) Incorporate this vulnerability into incident response plans to enable rapid detection and containment if exploitation is suspected.
