Executive brief
IBM Db2 Mirror for i is a database management tool used to replicate and manage IBM i database systems. This vulnerability allows an authenticated remote attacker to disable server-side input validation through a request parameter, potentially allowing bypass of security checks designed to protect the database from malicious queries or commands.
Technical details
The vulnerability is classified as a Protection Mechanism Failure (CWE-693) in IBM Db2 Mirror for i versions 7.4, 7.5, and 7.6. An authenticated remote attacker can manipulate a request parameter to disable server-side input validation, bypassing security controls that would normally filter or sanitize user input. The attack requires valid credentials and network access to the Db2 Mirror for i GUI. Successful exploitation could allow attackers to inject malicious commands or queries that would normally be blocked by validation logic. IBM has released security updates to address this and multiple other vulnerabilities affecting the product.
