CRLF injection in Refit's [Header], [HeaderCollection] and [Authorize] attributes
Critical

SummaryThe various header-related Refit attributes (Header, HeaderCollection and Authorize) are vulnerable to CRLF injection. DetailsThe way HTTP headers are added to a request is via the This means that any headers added to a refit request are vulnerable to CRLF-injection. In general, CRLF-injection into a HTTP header (when using HTTP/1.1) means that one can inject additional HTTP headers or smuggle whole HTTP requests. PoCThe below example code creates a console app that takes one command line variable (a bearer token) and then makes a request to some status page with the provided token inserted in the "Authorization" header: This application is now vulnerable to CRLF-injection, and can thus be abused to for example perform request splitting and thus server side request forgery (SSRF): The application intends to send a single request of the form: But as the application is vulnerable to CRLF injection the above command will instead result in the following two requests being sent: and This can be confirmed by checking the access logs on the server where these commands were run (with ImpactIf an application using the Refit library passes a user-controllable value through to a header, then that application becomes vulnerable to CRLF-injection. This is not necessarily a security issue for a command line application like the one above, but if such code were present in a web application then it becomes vulnerable to request splitting (as shown in the PoC) and thus Server Side Request Forgery. Strictly speaking this is a potential vulnerability in applications using Refit, not in Refit itself, but I would argue that at the very least there needs to be a warning about this behaviour in the Refit documentation.

SummaryThe various header-related Refit attributes (Header, HeaderCollection and Authorize) are vulnerable to CRLF injection. DetailsThe way HTTP headers are added to a request is via the This means that any headers added to a refit request are vulnerable to CRLF-injection. In general, CRLF-injection into a HTTP header (when using HTTP/1.1) means that one can inject additional HTTP headers or smuggle whole HTTP requests. PoCThe below example code creates a console app that takes one command line variable (a bearer token) and then makes a request to some status page with the provided token inserted in the "Authorization" header: This application is now vulnerable to CRLF-injection, and can thus be abused to for example perform request splitting and thus server side request forgery (SSRF): The application intends to send a single request of the form: But as the application is vulnerable to CRLF injection the above command will instead result in the following two requests being sent: and This can be confirmed by checking the access logs on the server where these commands were run (with ImpactIf an application using the Refit library passes a user-controllable value through to a header, then that application becomes vulnerable to CRLF-injection. This is not necessarily a security issue for a command line application like the one above, but if such code were present in a web application then it becomes vulnerable to request splitting (as shown in the PoC) and thus Server Side Request Forgery. Strictly speaking this is a potential vulnerability in applications using Refit, not in Refit itself, but I would argue that at the very least there needs to be a warning about this behaviour in the Refit documentation.
