Resin Pro 4.0.39 and possibly earlier versions improperly performs Unicode transformations.
CWE-20: Improper Input Validation
Resin Pro 4.0.39 and possibly earlier versions perform incorrect Unicode transformations on output to HTTP responses for ISO-8859-1. This allows an attacker to bypass filtering/encoding/validation done prior to the output transformation. An attacker can use specially crafted input characters on pages that by default respond with ISO-8859-1 (or can be forced to use it) to bypass filtering/encoding/validation done prior to the output transformation.
A remote unauthenticated attacker may be able to perform XSS, Open Redirect, and other attacks that depend on the logic being enforced prior to the transformation and bypassed due to this vulnerability.
