Experiments show that +several HTTP server applications will attach meaning to the choice of +whether or not a particular character was percent-encoded, even when +the percent-encoding is unnecessary from the perspective of parsing +the URI into its component fields. + +Fix by storing the originally encoded substrings for the path, query, +and fragment fields and using these original encoded versions when +reconstructing a URI string. The path field is also stored as a +decoded string, for use by protocols such as TFTP that communicate +using raw strings rather than URI-encoded strings. All other fields +(such as the username and password) continue to be stored only in +their decoded versions since nothing ever needs to know the originally +encoded versions of these fields. + +Signed-off-by: Michael Brown <mcb30@ipxe.org> + +Conflict:NA +Reference:https://github.com/ipxe/ipxe/commit/1844aacc837bf81cb1959fa65f2e52dcc70a0cae +--- + src/core/uri.c | 131 +++++++++++++++++++++++++---------------- + src/include/ipxe/uri.h | 31 +++++++--- + src/net/tcp/httpcore.c | 4 +- + src/tests/uri_test.c | 53 +++++++++++++---- + src/usr/imgmgmt.c | 4 +- + 5 files changed, 148 insertions(+), 75 deletions(-) + +diff --git a/src/core/uri.c b/src/core/uri.c +index e9e512ab4a..a0f79e9ec1 100644 +--- a/src/core/uri.c ++++ b/src/core/uri.c +@@ -79,12 +79,10 @@ size_t uri_decode ( const char *encoded, void *buf, size_t len ) { + /** + * Decode URI field in-place + * +- * @v uri URI +- * @v field URI field index ++ * @v encoded Encoded field, or NULL + */ +-static void uri_decode_inplace ( struct uri *uri, unsigned int field ) { +- const char *encoded = uri_field ( uri, field ); +- char *decoded = ( ( char * ) encoded ); ++static void uri_decode_inplace ( char *encoded ) { ++ char *decoded = encoded; + size_t len; + + /* Do nothing if field is not present */ +@@ -150,7 +148,7 @@ static int uri_character_escaped ( char c, unsigned int field ) { + * parser but for any other URI parsers (e.g. HTTP query + * string parsers, which care about '=' and '&'). + */ +- static const char *escaped[URI_FIELDS] = { ++ static const char *escaped[URI_EPATH] = { + /* Scheme or default: escape everything */ + [URI_SCHEME] = "/#:@?=&", + /* Opaque part: escape characters which would affect +@@ -172,20 +170,21 @@ static int uri_character_escaped ( char c, unsigned int field ) { + * appears within paths. + */ + [URI_PATH] = "#:@?", +- /* Query: escape everything except '/', which +- * sometimes appears within queries. +- */ +- [URI_QUERY] = "#:@?", +- /* Fragment: escape everything */ +- [URI_FRAGMENT] = "/#:@?", + }; + +- return ( /* Always escape non-printing characters and whitespace */ +- ( !
