Technical ContextAI · show details

This vulnerability is classified as Cross-Site Request Forgery (CSRF) (CWE-352), which allows attackers to trick authenticated users into performing unintended actions. A Cascading Style Sheets (CSS) injection vulnerability in Swagger UI before 3.23.11 allows attackers to use the Relative Path Overwrite (RPO) technique to perform CSS-based input field value exfiltration, such as exfiltration of a CSRF token value. In other words, this product intentionally allows the embedding of untrusted JSON data from remote servers, but it was not previously known that <style>@import within the JSON data was a functional attack method. Affected products include: Smartbear Swagger Ui, Oracle Banking Apis, Oracle Banking Digital Experience, Oracle Banking Platform, Oracle Primavera Gateway. Version information: before 3.23.11.
