CVE-2006-0586 in Oracle
Summary
by MITRE
Multiple SQL injection vulnerabilities in Oracle 10g Release 1 before CPU Jan 2006 allow remote attackers to execute arbitrary SQL commands via multiple parameters in (1) ATTACH_JOB, (2) HAS_PRIVS, and (3) OPEN_JOB functions in the SYS.KUPV$FT package; and (4) UPDATE_JOB, (5) ACTIVE_JOB, (6) ATTACH_POSSIBLE, (7) ATTACH_TO_JOB, (8) CREATE_NEW_JOB, (9) DELETE_JOB, (10) DELETE_MASTER_TABLE, (11) DETACH_JOB, (12) GET_JOB_INFO, (13) GET_JOB_QUEUES, (14) GET_SOLE_JOBNAME, (15) MASTER_TBL_LOCK, and (16) VALID_HANDLE functions in the SYS.KUPV$FT_INT package. NOTE: due to the lack of relevant details from the Oracle advisory, a separate CVE is being created since it cannot be conclusively proven that these issues has been addressed by Oracle. It is unclear which, if any, Oracle Vuln# identifiers apply to these issues.

The vulnerability described in CVE-2006-0586 represents a critical SQL injection flaw affecting Oracle 10g Release 1 systems prior to the January 2006 Critical Patch Update. This vulnerability resides within the SYS.KUPV$FT and SYS.KUPV$FT_INT database packages, which are part of Oracle's Database Recovery Manager (RMAN) and Oracle Data Pump functionality. These packages handle various administrative operations including job management, attachment processes, and database object manipulation. The flaw stems from insufficient input validation and improper parameter handling within multiple stored procedures, creating opportunities for malicious actors to inject arbitrary SQL commands directly into the database execution context.
The technical implementation of this vulnerability occurs through multiple attack vectors within the database package interfaces. Specifically, the ATTACH_JOB, HAS_PRIVS, and OPEN_JOB functions in the SYS.KUPV$FT package accept user-supplied parameters that are not properly sanitized before being incorporated into SQL queries. Similarly, the SYS.KUPV$FT_INT package contains fifteen additional vulnerable functions including UPDATE_JOB, ACTIVE_JOB, and DELETE_JOB that process user input without adequate validation mechanisms. These functions typically construct dynamic SQL statements by concatenating user-provided parameters directly into query strings, which violates fundamental security principles and creates exploitable injection points.
From an operational perspective, this vulnerability presents a severe risk to database security and integrity. Remote attackers can leverage these injection points to execute unauthorized database operations including data manipulation, unauthorized access to sensitive information, and potential privilege escalation. The impact extends beyond simple data theft as attackers could modify database structures, delete critical information, or even gain administrative control over the database system. The vulnerability affects the underlying database engine rather than application layers, making it particularly dangerous as it operates at the core database functionality level. This type of vulnerability aligns with CWE-89 which specifically addresses SQL injection flaws, and represents a classic example of how improper input validation can lead to complete system compromise.
The exploitation of these vulnerabilities requires minimal privileges since the affected functions are part of the database's internal package structure. Attackers typically need only network access to the database server and knowledge of the vulnerable function signatures to craft malicious payloads. The attack surface is particularly broad given that the vulnerability spans multiple functions within two database packages, increasing the probability of successful exploitation. Security professionals should note that this vulnerability demonstrates the importance of least privilege principles and proper input validation, as it operates through legitimate database administrative functions that should not be directly exposed to untrusted input sources. The ATT&CK framework categorizes this as a database injection technique, specifically falling under the T1566.001 sub-technique for SQL injection, which emphasizes the exploitation of database application vulnerabilities to execute arbitrary commands.
Mitigation strategies should focus on immediate patching with the January 2006 Oracle Critical Patch Update, which addresses these specific vulnerabilities. Organizations should also implement network segmentation to limit access to database servers, enforce strict firewall rules, and monitor database activity for suspicious patterns. Additionally, database administrators should review and restrict access to the vulnerable packages, implement proper input validation at the application level, and consider using Oracle's built-in security features such as Oracle Database Vault. Regular security assessments and vulnerability scanning should be conducted to identify similar issues in other database components, as this vulnerability type often indicates broader security gaps in database configuration and access control mechanisms.
