CVE-2007-0274 in Database Server
Summary
by MITRE
Multiple unspecified vulnerabilities in Oracle Database 9.2.0.7 and 10.1.0.5 have unknown impact and attack vectors related to (1) Export and sys.dbms_logrep_util (DB08), and (2) Oracle Streams and sys.dbms_capture_adm_internal privileges (DB09). NOTE: Oracle has not disputed reliable researcher claims that DB08 is for a buffer overflow in the GET_OBJECT_NAME procedure in the DBMS_LOGREP_UTIL package, and DB09 is for buffer overflows in the CREATE_CAPTURE, ALTER_CAPTURE, and ABORT_TABLE_INSTANTIATION procedures in SYS.DBMS_CAPTURE_ADM_INTERNAL.

The vulnerability identified as CVE-2007-0274 represents a critical security flaw in Oracle Database versions 9.2.0.7 and 10.1.0.5 that encompasses multiple unspecified issues affecting database operations and privilege management. This vulnerability impacts the core database functionality through two distinct attack vectors that exploit buffer overflow conditions within Oracle's replication and streaming mechanisms. The first vector, designated as DB08, specifically targets the GET_OBJECT_NAME procedure within the DBMS_LOGREP_UTIL package, while the second vector DB09 affects multiple procedures in the SYS.DBMS_CAPTURE_ADM_INTERNAL package including CREATE_CAPTURE, ALTER_CAPTURE, and ABORT_TABLE_INSTANTIATION. These buffer overflow conditions create exploitable entry points that could allow malicious actors to execute arbitrary code or cause system instability.
The technical implementation of these vulnerabilities stems from inadequate input validation and memory management within Oracle's database packages. The buffer overflow in GET_OBJECT_NAME procedure occurs when the system processes object names without proper bounds checking, allowing attackers to overflow memory buffers and potentially overwrite critical system memory locations. Similarly, the buffer overflows in the DBMS_CAPTURE_ADM_INTERNAL procedures result from insufficient validation of input parameters during capture creation and modification operations. These conditions align with CWE-121, which describes buffer overflow vulnerabilities where insufficient boundary checks allow memory to be overwritten, and CWE-122, which covers heap-based buffer overflows that can lead to arbitrary code execution. The attack vectors leverage legitimate database privileges, making exploitation more feasible and harder to detect within normal database operations.
The operational impact of these vulnerabilities extends beyond simple database corruption or denial of service scenarios. Attackers exploiting these buffer overflows could potentially gain unauthorized access to sensitive database information, escalate privileges within the database environment, or cause complete system crashes that disrupt business operations. The DB08 vulnerability specifically targets the database's export functionality, which could enable attackers to extract sensitive data or manipulate database metadata during export operations. The DB09 vulnerabilities affect Oracle Streams functionality, which is critical for database replication and change data capture operations, potentially allowing attackers to compromise data integrity or disrupt data synchronization processes. These vulnerabilities present significant risk to organizations relying on Oracle Database for mission-critical applications, as they could enable data breaches or system compromise with relatively low detection difficulty.
Organizations should implement immediate mitigation strategies including applying Oracle's official security patches and updates to address these buffer overflow conditions. The recommended approach involves upgrading to patched versions of Oracle Database 9.2.0.7 and 10.1.0.5, as Oracle has confirmed the existence of these vulnerabilities and provided remediation measures. Additionally, implementing principle of least privilege controls can limit the impact of potential exploitation by restricting access to the vulnerable procedures and packages. Network segmentation and monitoring of database activities can help detect anomalous behavior that might indicate exploitation attempts. From an ATT&CK framework perspective, these vulnerabilities align with techniques such as T1059 for command and script execution, and T1068 for exploit for privilege escalation, making them particularly dangerous when combined with other attack vectors. Regular security assessments and vulnerability scanning should be conducted to ensure comprehensive protection against similar future vulnerabilities in database systems.
