CVE-2007-2113 in Database Server
Summary
by MITRE
SQL injection vulnerability in the Upgrade/Downgrade component (DBMS_UPGRADE_INTERNAL) for Oracle Database 10.1.0.5 allows remote authenticated users to execute arbitrary SQL commands via unknown vectors, aka DB07. NOTE: as of 20070424, Oracle has not disputed reliable claims that DB07 is actually for multiple issues.

The CVE-2007-2113 vulnerability represents a critical SQL injection flaw within Oracle Database's Upgrade/Downgrade component known as DBMS_UPGRADE_INTERNAL. This vulnerability specifically affects Oracle Database version 10.1.0.5 and enables remote authenticated attackers to execute arbitrary SQL commands through unspecified attack vectors. The vulnerability was designated as DB07 by Oracle, though the company later acknowledged that this designation actually encompassed multiple distinct issues rather than a single vulnerability. The technical nature of this flaw lies in the improper handling of user input within the database upgrade and downgrade functionality, creating opportunities for malicious SQL commands to be injected and executed with elevated privileges. This vulnerability operates at the database layer and requires authentication to exploit, making it particularly concerning as it allows attackers who have legitimate database access to escalate their privileges and execute unauthorized operations.
The operational impact of CVE-2007-2113 extends beyond simple data manipulation to encompass complete database compromise and potential lateral movement within network environments. Attackers leveraging this vulnerability can execute arbitrary SQL commands that may include data extraction, modification, or deletion operations, potentially leading to unauthorized access to sensitive information and system control. The vulnerability's classification under CWE-89 indicates it falls within the category of SQL injection flaws, which are among the most prevalent and dangerous security weaknesses in database applications. From an attacker perspective, this vulnerability aligns with ATT&CK technique T1078 which covers valid accounts and T1046 which covers network service scanning, as the attack requires authenticated access to the database system. The fact that this vulnerability affects the upgrade/downgrade functionality makes it particularly dangerous as database administrators often possess elevated privileges and may be working with sensitive system components during maintenance operations.
Mitigation strategies for CVE-2007-2113 should focus on immediate patching and access control improvements. Organizations must ensure they apply the relevant Oracle security patches released in response to this vulnerability, as the patch addresses the underlying SQL injection flaws in the DBMS_UPGRADE_INTERNAL component. Network segmentation and principle of least privilege should be enforced to limit access to database systems, particularly those with upgrade capabilities. Database administrators should implement strict input validation and parameterized queries to prevent similar issues from occurring in other database components. Monitoring and logging should be enhanced to detect unusual database activities, particularly during upgrade and downgrade operations. Additionally, organizations should conduct regular security assessments of their database environments and implement database activity monitoring solutions to detect potential exploitation attempts. The vulnerability's nature as a SQL injection issue means that defensive measures should include regular code reviews and security testing of database applications to prevent similar weaknesses from being introduced in custom database scripts and stored procedures.
