CVE-2025-53079 is an Absolute Path Traversal vulnerability identified in Samsung Electronics' Data Management Server (DMS), specifically affecting versions 2.0.0, 2.5.0.17, and 2.7.0.15. This vulnerability is classified under CWE-36, which involves improper validation of file paths, allowing an attacker to manipulate file system paths to access files outside the intended directory. In this case, an authenticated attacker with administrator privileges can exploit this flaw to read sensitive files on the server. The vulnerability does not require user interaction and can be exploited remotely over the network (AV:N), with low attack complexity (AC:L). However, it requires high privileges (PR:H), meaning the attacker must already have administrator-level access to the system. The impact is primarily on confidentiality, as the attacker can read sensitive files, but it does not affect integrity or availability. The CVSS v3.1 base score is 4.9, indicating a medium severity level. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published on July 29, 2025, and reserved on June 24, 2025. Given the nature of the vulnerability, it likely stems from insufficient sanitization or validation of file path inputs within the DMS software, allowing traversal sequences (e.g., ../) to access arbitrary files on the underlying filesystem.

For European organizations using Samsung Electronics Data Management Server, this vulnerability poses a significant risk to the confidentiality of sensitive data managed by the server. Since the attacker must already have administrator privileges, the threat is more relevant in scenarios where internal threats exist or where an attacker has compromised administrative credentials through other means (e.g., phishing, credential theft). The ability to read arbitrary files can lead to exposure of critical configuration files, credentials, or proprietary data, potentially facilitating further attacks or data breaches. This can have regulatory implications under GDPR, where unauthorized access to personal data can result in heavy fines and reputational damage. Organizations in sectors such as finance, healthcare, government, and critical infrastructure that rely on Samsung DMS for data management are particularly at risk. The medium severity score reflects the limited scope of exploitation (authenticated admin required) but does not diminish the importance of addressing the vulnerability promptly to prevent lateral movement or escalation of attacks within the network.

To mitigate CVE-2025-53079, European organizations should take the following specific actions: 1) Immediately audit and restrict administrator access to the Samsung DMS to only trusted personnel, implementing strict access controls and multi-factor authentication to reduce the risk of credential compromise. 2) Monitor and analyze logs for unusual file access patterns or attempts to access files outside expected directories, which may indicate exploitation attempts. 3) Apply any available patches or updates from Samsung Electronics as soon as they are released; if no patches are currently available, consider implementing compensating controls such as application-layer filtering or network segmentation to isolate the DMS server. 4) Conduct a thorough review of the DMS configuration to ensure that file path inputs are properly sanitized and that the server's file system permissions are restrictive, preventing unauthorized file reads even if traversal attempts occur. 5) Educate administrators on the risks of credential compromise and enforce strong password policies. 6) Consider deploying endpoint detection and response (EDR) solutions to detect suspicious activities related to file access on the DMS server. These measures will help reduce the attack surface and limit the potential impact of this vulnerability.
