CVE-2025-30483 is a vulnerability identified in Dell's Elastic Cloud Storage (ECS) product, including ObjectScale versions prior to 3.8.1.5 and 4.0.0.0 respectively. The vulnerability is classified under CWE-532, which pertains to the insertion of sensitive information into log files. Specifically, this flaw allows a low-privileged attacker with local access to the affected system to cause sensitive data to be written into log files. This can lead to unauthorized information disclosure if an attacker can access these logs. The vulnerability does not require user interaction and has a CVSS 3.1 base score of 5.5, indicating a medium severity level. The attack vector is local (AV:L), with low attack complexity (AC:L), requiring low privileges (PR:L), and no user interaction (UI:N). The impact is primarily on confidentiality (C:H), with no impact on integrity or availability. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is significant because log files often contain detailed operational data, and if sensitive information such as credentials, tokens, or personally identifiable information is logged improperly, it can be accessed by unauthorized users, leading to potential data breaches or further exploitation.

For European organizations using Dell ECS or ObjectScale, this vulnerability poses a risk of sensitive data leakage through improperly sanitized logs. Given that ECS is often deployed in enterprise environments for object storage, including critical data and backups, exposure of sensitive information could lead to compliance violations under GDPR and other data protection regulations. The confidentiality breach could facilitate lateral movement by attackers or insider threats escalating privileges or exfiltrating data. Since the vulnerability requires local access, the risk is heightened in environments where multiple users have access to the system or where attackers can gain initial footholds through other means. The lack of impact on integrity and availability reduces the risk of service disruption but does not diminish the importance of protecting sensitive information. European organizations in sectors such as finance, healthcare, and government, which rely heavily on secure storage solutions, could face reputational damage and regulatory penalties if this vulnerability is exploited.

To mitigate this vulnerability, European organizations should first ensure strict access controls to limit local access to trusted administrators only. Implementing robust monitoring and auditing of log file access can help detect unauthorized attempts to read sensitive logs. Organizations should apply the latest patches or updates from Dell as soon as they become available, even though no patch links are currently provided. In the interim, reviewing and sanitizing logging configurations to exclude sensitive information from logs is critical. This may involve disabling verbose logging or customizing log formats to mask or omit sensitive data fields. Additionally, encrypting log files at rest and in transit can reduce the risk of data exposure if logs are accessed by unauthorized users. Employing endpoint security solutions to detect and prevent unauthorized local access and maintaining strict user privilege management will further reduce exploitation risk. Regular security training for administrators on secure logging practices is also recommended.
