CVE-2007-0409 in WebLogic Server
Summary
by MITRE
BEA WebLogic 7.0 through 7.0 SP6, 8.1 through 8.1 SP4, and 9.0 initial release does not encrypt passwords stored in the JDBCDataSourceFactory MBean Properties, which allows local administrative users to read the cleartext password.

The vulnerability identified as CVE-2007-0409 affects BEA WebLogic Server versions 7.0 through 7.0 SP6, 8.1 through 8.1 SP4, and the initial release of version 9.0. This represents a critical security flaw in the application server's handling of database connection credentials within its management infrastructure. The vulnerability specifically targets the JDBCDataSourceFactory MBean Properties component where sensitive password information is stored in cleartext format rather than being properly encrypted. This weakness fundamentally undermines the security posture of WebLogic installations that rely on database connectivity for their operations, creating a significant attack surface for malicious actors who gain administrative access to the system.
The technical flaw stems from the improper storage mechanism within WebLogic's management bean architecture where database passwords are persisted without encryption, making them immediately accessible to any local administrative user who can access the MBean properties. This design decision creates a direct path for privilege escalation attacks, as unauthorized administrative access to the server would automatically grant access to database credentials without requiring additional cryptographic attacks or complex exploitation techniques. The vulnerability operates at the configuration management level rather than through network-based attacks, making it particularly dangerous in environments where local administrative access is not strictly controlled or where insider threats exist.
The operational impact of this vulnerability extends beyond simple credential exposure, as it enables attackers to gain unauthorized access to backend databases and potentially compromise entire data ecosystems. Local administrative users with access to the WebLogic management console can directly retrieve cleartext passwords from the JDBCDataSourceFactory MBean Properties, allowing them to establish database connections using legitimate credentials without requiring additional authentication mechanisms. This vulnerability directly violates security best practices outlined in the OWASP Top Ten and aligns with CWE-312, which specifically addresses the exposure of sensitive information through improper data handling. The attack vector is particularly concerning because it requires minimal technical skill and provides immediate access to database resources, making it a preferred target for both malicious insiders and external attackers who have achieved local administrative access.
Mitigation strategies for this vulnerability include immediate implementation of proper password encryption mechanisms within the WebLogic configuration management system, regular security audits of MBean properties, and strict access controls for administrative users. Organizations should implement the principle of least privilege for administrative accounts and establish robust monitoring of administrative activities within WebLogic environments. The recommended approach involves upgrading to patched versions of WebLogic Server where the vulnerability has been addressed, implementing additional layers of authentication for database access, and conducting comprehensive security assessments of configuration management systems. This vulnerability also highlights the importance of adhering to the NIST SP 800-53 security controls for access control and configuration management, ensuring that sensitive data is properly protected even when stored in management interfaces. The remediation process should include comprehensive testing to verify that password encryption is properly implemented and that no cleartext credentials remain accessible through MBean interfaces.
