- Summary
- percent-encoded path separator in URL host
- Details
-
The curl URL parser wrongly accepts percent-encoded URL separators like '/' when decoding the hostname part of a URL, making it a different URL using the wrong hostname when it is later retrieved.
For example, a URL like
http://example.com%2F10.0.0.1/, would be allowed by the parser and get transposed intohttp://example.com/10.0.0.1/. This flaw can be used to circumvent filters, checks and more. - References
