Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting'), where the product receives data from an http agent/component (e.g., web server, proxy, browser, etc.), but it does not neutralize or incorrectly neutralizes cr and lf characters before the data is included in outgoing http headers. In Github.com/gin gonic/gin, software state validation or input boundaries are circumvented during processing.
