Summary

Reflected XSS in go-httpbin due to unrestricted client control over Content-Type

Details

Description

The go-httpbin framework is vulnerable to XSS as the user can control the Response Content-Type from GET parameter. This allows attacker to execute cross site scripts in victims browser.

Affected URLs:

/response-headers?Content-Type=text/html&xss=%3Cimg/src/onerror=alert(%27xss%27)%3E
/base64/PGltZy9zcmMvb25lcnJvcj1hbGVydCgneHNzJyk+?content-type=text/html
/base64/decode/PGltZy9zcmMvb25lcnJvcj1hbGVydCgneHNzJyk+?content-type=text/html

Steps to reproduce:

Visit one of the above mentioned URLs.
XSS window will popup

Suggested fix

Allow Only Safe Content-Type Values Or give users option to define whitelisted Content-Type headers

Criticality

The following can be major impacts of the issue: * Access to victim's sensitive Personal Identifiable Information. * Access to CSRF token * Cookie injection * Phishing * And any other thing Javascript can perform
