XQuery Injection
XQuery Injection
XQuery Injection
CWE-652
Short description
The product uses external input to dynamically construct an XQuery expression used to retrieve data from an XML database, but it does not neutralize or incorrectly neutralizes that input. This allows an attacker to control the structure of the query.
Extended description
The net effect is that the attacker will have control over the information selected from the XML database and may use that ability to control application flow, modify logic, retrieve unauthorized data, or bypass important checks (e.g. authentication).
Best practices to prevent this CWE
Phase: Implementation
Use parameterized queries. This will help ensure separation between data plane and control plane.
Phase: Implementation
Properly validate user input. Reject data where appropriate, filter where appropriate and escape where appropriate. Make sure input that will be used in XQL queries is safe in that context.
