N/A
Not availableNo severity ratings or metrics are available. When they are, we'll update the corresponding info on the page.
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.
