CVE-2007-2111 in Database Server
Summary
by MITRE
SQL injection vulnerability in the SYS.DBMS_AQADM_SYS package in Oracle Database 9.0.1.5, 9.2.0.7, and 10.1.0.5 allows remote authenticated users to inject arbitrary SQL commands via unknown vectors, aka DB04. NOTE: as of 20070424, Oracle has not disputed reliable claims that DB04 is actually for multiple vulnerabilities.

The vulnerability identified as CVE-2007-2111 represents a critical SQL injection flaw within Oracle Database's SYS.DBMS_AQADM_SYS package, affecting versions 9.0.1.5, 9.2.0.7, and 10.1.0.5. This vulnerability operates at the database layer and specifically targets the Advanced Queuing administrative functionality that allows for message queuing operations within Oracle environments. The flaw enables authenticated remote attackers to execute arbitrary SQL commands by exploiting insufficient input validation within the package's internal procedures, creating a pathway for privilege escalation and unauthorized data access. The vulnerability's classification aligns with CWE-89, which specifically addresses SQL injection weaknesses where untrusted data is incorporated into SQL commands without proper sanitization or parameterization.
The technical exploitation of this vulnerability occurs through the manipulation of input parameters within the DBMS_AQADM_SYS package procedures that handle queue administration tasks. Attackers can craft malicious inputs that bypass normal input validation mechanisms, allowing them to inject additional SQL statements that execute with the privileges of the authenticated user. This particular vector is particularly dangerous because it operates within the database's system schema, potentially providing attackers with elevated privileges and access to sensitive system information. The vulnerability's impact extends beyond simple data theft, as it can enable attackers to modify database structures, execute administrative commands, and potentially gain access to other system resources through the database's internal interfaces. The attack surface is broadened by the fact that this vulnerability affects multiple Oracle Database versions, making it a widespread concern for organizations maintaining legacy systems.
The operational impact of CVE-2007-2111 is severe and multifaceted, particularly in enterprise environments where Oracle Database serves as a critical component for business applications and data storage. Organizations running affected database versions face potential data breaches, unauthorized access to sensitive corporate information, and possible system compromise through privilege escalation attacks. The vulnerability's remote execution capability means that attackers do not require physical access to the database server, making it particularly dangerous in networked environments where database access is granted across network boundaries. This vulnerability directly violates the principle of least privilege and can lead to cascading security failures when database users have elevated permissions. The attack can result in complete database compromise, data exfiltration, and potential disruption of business operations, with the severity amplified by the fact that the vulnerability affects multiple database versions and can be exploited by authenticated users who may already have legitimate access to the system.
Organizations should implement immediate mitigations including applying Oracle's security patches and updates as released in their quarterly database security alerts, which would address this specific vulnerability through proper input validation and parameterization of database calls. Network segmentation and access controls should be strengthened to limit access to database administrative interfaces and the DBMS_AQADM_SYS package specifically. Database auditing and monitoring should be enhanced to detect unusual SQL command patterns and potential injection attempts. The vulnerability's classification under ATT&CK technique T1078.004 for valid accounts and T1566 for credential access highlights the need for comprehensive monitoring of database activities and user behavior analytics to detect anomalous access patterns. Additionally, implementing proper database configuration practices such as disabling unnecessary administrative packages and ensuring that database users have only the minimum required privileges will significantly reduce the potential impact of this vulnerability. Organizations should also consider implementing database activity monitoring solutions that can detect and alert on suspicious SQL injection attempts and unauthorized administrative command executions.
