Summary
by MITRE
Unspecified vulnerability in the Change Data Capture (CDC) component in Oracle Database 9.2.0.7, 10.1.0.5, and 10.2.0.2 has unknown impact and attack vectors, aka DB09. NOTE: as of 20070424, oracle has not disputed reliable claims that this issue involves multiple SQL injection vulnerabilities in the DBMS_CDC_PUBLISH with remote authenticated vectors involving the "java classes in CDC.jar."

The vulnerability identified as CVE-2007-2115 represents a critical security flaw within Oracle Database's Change Data Capture component, specifically affecting versions 9.2.0.7, 10.1.0.5, and 10.2.0.2. This issue falls under the broader category of database security vulnerabilities that can potentially allow unauthorized data access and manipulation. The Change Data Capture functionality is designed to track and record changes to database tables, making it a critical component for data integration and replication processes. The unspecified nature of the vulnerability's impact and attack vectors initially raised concerns among security professionals, as it suggested the potential for significant security implications within Oracle Database environments.
The technical flaw manifests through multiple SQL injection vulnerabilities present in the DBMS_CDC_PUBLISH package, particularly when utilizing the java classes contained within the CDC.jar file. This vulnerability specifically affects remote authenticated attack vectors, meaning that an attacker must first establish valid credentials to the database system to exploit the flaw. The SQL injection aspect of this vulnerability allows malicious actors to inject arbitrary SQL commands into the database through the CDC component, potentially enabling them to execute unauthorized operations, extract sensitive data, or manipulate database structures. The vulnerability's presence in the Java-based CDC.jar library indicates that the attack surface extends beyond traditional SQL injection vectors into the realm of Java bytecode manipulation.
The operational impact of this vulnerability extends far beyond simple data theft, as it can enable attackers to compromise the integrity and availability of database systems. Organizations relying on Oracle Database's Change Data Capture for replication, auditing, or data integration processes face significant risk from this vulnerability, as it could allow attackers to manipulate the change data capture mechanisms themselves. The attack vector involving authenticated access means that insider threats or compromised accounts pose a particular risk, as the vulnerability can be exploited through legitimate database connections. This vulnerability also impacts the confidentiality of database operations, as the SQL injection capabilities could potentially expose sensitive data that should be protected by database access controls.
Mitigation strategies for CVE-2007-2115 should focus on immediate patching of affected Oracle Database versions, as Oracle would have released security patches addressing these specific SQL injection vulnerabilities in the DBMS_CDC_PUBLISH package. Organizations should also implement network segmentation to limit access to database systems, enforce strict access controls and authentication mechanisms, and conduct regular security assessments of database components. The vulnerability's classification aligns with CWE-89, which specifically addresses SQL injection flaws, and falls within the ATT&CK technique T1078 for valid accounts and T1566 for credential access through database systems. Additionally, organizations should consider implementing database activity monitoring solutions to detect anomalous behavior that might indicate exploitation attempts, as the vulnerability could be used to bypass traditional database security controls and access sensitive information through legitimate database interfaces.
