CVE-2005-4832 in Oracle10g
Summary
by MITRE
SQL injection vulnerability in the Oracle Database Server 10g allows remote authenticated users to execute arbitrary SQL commands with elevated privileges via the SUBSCRIPTION_NAME parameter in the (1) SYS.DBMS_CDC_SUBSCRIBE and (2) SYS.DBMS_CDC_ISUBSCRIBE packages, a different vector than CVE-2005-1197.

The vulnerability described in CVE-2005-4832 represents a critical SQL injection flaw within Oracle Database Server 10g that exploits the SUBSCRIPTION_NAME parameter in two specific database packages. This vulnerability specifically affects the SYS.DBMS_CDC_SUBSCRIBE and SYS.DBMS_CDC_ISUBSCRIBE procedures, which are part of Oracle's Change Data Capture functionality designed to track and manage database changes. The flaw allows authenticated remote attackers to execute arbitrary SQL commands with elevated privileges, making it particularly dangerous as it bypasses normal access controls and operates at a system-level privilege escalation vector.
This SQL injection vulnerability operates through the improper handling of user input within the subscription name parameter, where the database server fails to adequately sanitize or validate input before incorporating it into SQL execution statements. The vulnerability is classified under CWE-89 as SQL injection, but differs from CVE-2005-1197 in its attack vector and target procedures, indicating a more specific pathway for exploitation within the Oracle database's change data capture mechanisms. The affected packages are part of Oracle's comprehensive database management system and are typically accessible through database connections that have appropriate authentication credentials, making the attack surface more manageable for determined adversaries.
The operational impact of this vulnerability extends beyond simple data manipulation as it enables attackers with valid database credentials to escalate their privileges and execute commands with system-level access. This elevated privilege execution capability allows adversaries to potentially access sensitive data, modify database structures, manipulate transaction logs, and potentially compromise the entire database system. The vulnerability particularly affects organizations that rely heavily on Oracle's change data capture features for database monitoring and replication, as these systems become potential attack vectors for privilege escalation attacks. The remote execution capability means attackers do not require physical access to the database server, making the vulnerability exploitable across network boundaries.
Organizations should implement immediate mitigations including applying Oracle's official security patches and updates that address this specific vulnerability in the database server's change data capture functionality. Database administrators should also consider implementing additional input validation measures and privilege separation techniques to limit the potential impact of such vulnerabilities. The ATT&CK framework categorizes this vulnerability under privilege escalation techniques, specifically leveraging database-specific attack vectors that allow adversaries to gain elevated system privileges through exploitation of database-specific functionalities. Security monitoring should focus on detecting unusual database activity patterns, particularly around the affected packages, and implementing database activity monitoring solutions that can detect anomalous SQL command execution patterns that may indicate exploitation attempts.
