Vulnerability Data

IBM Db2 for Linux, UNIX and Windows (includes Db2 Connect Server) could allow a user to cause a denial of service by executing a query that invokes the JSON_Object scalar function, which may trigger an unhandled exception leading to abnormal…

Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires the system to handle error conditions (such as unhandled exceptions in JSON_Object) without resulting in abnormal termination.

prevent

Requires protection against denial-of-service attacks that can be triggered by crafted queries causing server crashes.

prevent

Mandates timely remediation of the software flaw that allows the JSON_Object function to trigger an unhandled exception.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require parameterized queries and input neutralization to prevent query-logic injection.

detects

Security testing in development catches injection vulnerabilities before release but does not itself implement the fix.

prevents

Secure development life cycle mandates input validation and query parameterization that directly prevent injection flaws.

prevents

Application security requirements explicitly call for controls against injection and improper query construction.

prevents

Secure architecture principles reduce the likelihood of query-logic flaws but do not prescribe the specific coding practice.

prevents

Secure coding standards require proper neutralization of special elements in all data queries.

prevents

Outsourced development agreements can require secure coding practices, indirectly mitigating the weakness.
