CVE-2006-0265 in Database Server
Summary
by MITRE
Multiple unspecified vulnerabilities in Oracle Database server 8.1.7.4, 9.0.1.5, 9.2.0.7, 10.1.0.5, and 10.2.0.1 have unspecified impact and attack vectors, as identified by Oracle Vuln# (1) DB17 in the Oracle Text component and (2) DB18 in the Program Interface Network component. NOTE: details are unavailable from Oracle, but they have not publicly disputed a claim by a reliable independent researcher that states that DB17 involves SQL injection in the (a) VALIDATE_STATEMENT and BUILD_DML functions in CTXSYS.DRILOAD; (b) CLEAN_DML function in CTXSYS.DRIDML; (c) GET_ROWID function in CTXSYS.CTX_DOC; (d) BROWSE_WORDS function in CTXSYS.CTX_QUERY; and (e) ODCIINDEXTRUNCATE, ODCIINDEXDROP, and ODCIINDEXDELETE functions in CATINDEXMETHODS.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

The vulnerability identified as CVE-2006-0265 represents a critical security flaw within Oracle Database server versions 8.1.7.4, 9.0.1.5, 9.2.0.7, 10.1.0.5, and 10.2.0.1 affecting multiple components including Oracle Text and Program Interface Network. This vulnerability stems from unspecified issues within the database server that were catalogued under Oracle vulnerability identifiers DB17 and DB18, with DB17 specifically linked to the Oracle Text component and DB18 to the Program Interface Network component. The lack of detailed information from Oracle initially created uncertainty around the true scope and impact of these vulnerabilities, though independent researchers were able to provide substantial evidence regarding the nature of the security flaws.
The technical implementation of the vulnerability primarily involves SQL injection attacks targeting specific database functions within the Oracle Text component. The identified attack vectors include the VALIDATE_STATEMENT and BUILD_DML functions within CTXSYS.DRILOAD, the CLEAN_DML function in CTXSYS.DRIDML, the GET_ROWID function in CTXSYS.CTX_DOC, the BROWSE_WORDS function in CTXSYS.CTX_QUERY, and several functions within CATINDEXMETHODS including ODCIINDEXTRUNCATE, ODCIINDEXDROP, and ODCIINDEXDELETE. These functions are part of Oracle's text indexing and search capabilities, making them particularly dangerous as they can be exploited to manipulate database queries and potentially execute unauthorized commands. The vulnerability manifests when user-supplied input is not properly sanitized before being processed by these functions, creating opportunities for attackers to inject malicious SQL code.
From an operational standpoint, this vulnerability presents significant risks to database security and data integrity. The exploitation of these SQL injection flaws could allow unauthorized users to access sensitive data, modify database contents, or even execute administrative commands on the database server. The impact extends beyond simple data theft as attackers could potentially escalate privileges, disrupt database operations, or establish persistent access points within the database environment. Given that these vulnerabilities affect multiple versions of Oracle Database, organizations running any of these specific versions face substantial risk, particularly in environments where database access is not properly restricted or where database users have elevated privileges.
The attack surface for this vulnerability is particularly concerning as it affects core database functionality components that are commonly used in enterprise applications. The functions targeted by this vulnerability are integral to Oracle's text search and indexing capabilities, making them frequently accessed components that could be exploited by attackers with minimal detection difficulty. This vulnerability aligns with CWE-89, which categorizes SQL injection as a code quality weakness that can lead to unauthorized access and data manipulation. From an attack framework perspective, this vulnerability maps to techniques described in the MITRE ATT&CK framework under the 'Command and Control' and 'Credential Access' domains, as attackers could potentially use these vulnerabilities to establish persistent access and extract sensitive information from database systems. Organizations should prioritize immediate patching of affected systems and implement network segmentation to limit exposure, while also monitoring database access logs for suspicious activity that might indicate exploitation attempts.
