The vulnerability identified as CVE-2015-4790 represents a significant security flaw within Oracle Berkeley DB's Data Store component, affecting multiple versions including 11.2.5.1.29, 11.2.5.2.42, 11.2.5.3.28, and 12.1.6.0.35. This issue falls under the category of unspecified vulnerabilities, indicating that the exact technical details of the flaw remain undisclosed in the public domain. The vulnerability's classification as affecting confidentiality, integrity, and availability demonstrates its potential to compromise the fundamental security pillars of systems utilizing this database component. The fact that this vulnerability operates through unknown vectors suggests that attackers may exploit it using methods not covered by the previously identified CVEs, making it particularly concerning for security professionals who must account for novel attack surfaces.
The technical nature of this vulnerability within the Data Store component implies that it likely resides in the database's core data management and storage mechanisms. As a local privilege escalation vulnerability, it provides attackers with elevated access rights to manipulate database contents, potentially leading to unauthorized data modification, information disclosure, or service disruption. The unspecified nature of the attack vectors means that the exploitation methods could involve memory corruption issues, improper access controls, or other undetermined technical weaknesses that allow local users to gain privileges beyond their normal operational scope. This characteristic places the vulnerability in the category of potentially severe flaws that could be leveraged to establish persistent access or cause widespread system compromise.
From an operational impact perspective, CVE-2015-4790 poses substantial risks to organizations relying on Oracle Berkeley DB for critical data storage operations. The vulnerability's potential to affect confidentiality means that sensitive data could be accessed by unauthorized local users, while its impact on integrity suggests that data modification or corruption might occur without detection. The availability component indicates that system services could be disrupted or rendered unavailable, potentially causing business continuity issues. Organizations using these specific versions of Oracle Berkeley DB face the risk of unauthorized data access, modification, or deletion, with the potential for cascading effects throughout their database infrastructure.
Security mitigations for this vulnerability should focus on immediate version updates to patched releases of Oracle Berkeley DB, as recommended by Oracle's security advisories. System administrators should implement strict access controls and monitor for unusual local user activities that might indicate exploitation attempts. The vulnerability's classification as a local privilege escalation issue means that additional defensive measures such as privilege separation, regular security audits, and comprehensive monitoring of system logs should be implemented. Organizations should also consider implementing network segmentation to limit local access to database systems and establish robust incident response procedures to address potential exploitation attempts. This vulnerability aligns with attack patterns documented in the MITRE ATT&CK framework under privilege escalation and defense evasion techniques, emphasizing the need for comprehensive security posture assessments. The specific impact on data store components places this vulnerability within CWE categories related to data integrity and access control failures, requiring systematic remediation approaches that address both immediate patching needs and long-term architectural security improvements.
