Description
The software 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.
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).
Modes of Introduction:
– Implementation
Likelihood of Exploit: High
Related Weaknesses
CWE-943
CWE-91
Consequences
Confidentiality: Read Application Data
An attacker might be able to read sensitive information from the XML database.
Potential Mitigations
Phase: Implementation
Description:
Use parameterized queries. This will help ensure separation between data plane and control plane.
Phase: Implementation
Description:
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.
