DescriptionCVE.org
IBM Db2 for Linux, UNIX and Windows (includes Db2 Connect Server) 11.5.0 through 11.5.9 and 12.1.0 through 12.1.3 is vulnerable to an XML external entity injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resources.
Executive ViewAI
IBM Db2 databases running version 12.1.3 and earlier are vulnerable to XML External Entity (XXE) attacks that could allow attackers to access sensitive data, cause denial of service, or execute unauthorized operations. Organizations using Db2 for critical data storage face potential data breaches and operational disruption until remediation is implemented.
Disable XML external entity processing in Db2 configuration if feature is not required for business operations; implement Web Application Firewall (WAF) rules to detect and block XXE payloads; restrict network access to Db2 instances using firewall and VPN controls; disable DTD (Document Type Definition) processing where possible; implement input validation and sanitization for all XML data; enable database activity monitoring and alerting for suspicious XML-related queries; apply principle of least privilege to database accounts accessing XML functionality.
