CWE-598: Use of GET Request Method With Sensitive Query Strings
What it is
The web application uses the HTTP GET method to process a request and includes sensitive information in the query string of that request.

- Medium
- Likelihood of exploit
- Not rated by MITRE
- Introduced during
- Architecture and Design, Implementation
- Exploited in the wild
- No CVE in CISA's catalog
What an attacker can do
- Read Application Data (Confidentiality)
How to prevent it
Implementation
- When sensitive information is sent, use the POST method (e.g. registration form).
How to find it
- Automated Static Analysis. Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)
