Short explanation
HTTP::Parser::XS versions before 0.18 for Perl truncate PATH_INFO at an encoded NUL byte in parse_http_request (S0).
A remote attacker can send a path that a proxy or filter checks in full while the application routes on a shorter one (S0).
What should be done?
- Update HTTP::Parser::XS to version 0.18 or later
- Follow vendor advisories
Chain of evidence and sources
HTTP::Parser::XS 0.18 öncesi sürümler PATH_INFO değerini kodlanmış NUL baytında kesmektedir.

Show the technical text from the sources
HTTP::Parser::XS versions before 0.18 for Perl truncate PATH_INFO at an encoded NUL byte in parse_http_request. The XS parser URL-decodes the request path and measures the result with strlen(), so PATH_INFO ends at the first byte decoded from %00. The pure-Perl backend is not affected. A remote attacker can send a path that a proxy or filter checks in full while the application routes on a shorter one.
