|/ | | | | | | | | | | | | | | | | | | | | | | | | | Libcurl expects the value of the CURLOPT_RESOLVE configurations to be an array of strings, those strings containing a comma delimited list of resolved IPs for each host:port combination. The original code here does create that array with the host:port:ip combination, but multiple ips for a single host:port result in additional array entries, rather than adding them to the end of the string with a comma. Per the libcurl docs, the `CURLOPT_RESOLVE` array entries should match the syntax `host:port:address[,address]`. This creates a function-scoped associative array which uses `host:port` as the key (which are supposed to be unique and this ensures that), and the value is an array containing IP strings (ipv4 or ipv6). Once the associative array is populated, it is then set to the CURLOPT_RESOLVE array, imploding the ip arrays using a comma delimiter so the array syntax matches the expected by libcurl. Note that this reorders the "foreach ip" and "foreach port" loops. Rather than looping over ips then ports, we now loop over ports then ips, since ports are part of the unique host:port map, and multiple ips can exist therein.

Whilst we currently state that SSRF is generally outside of our threat model, this is something where we should invest to improve this. Signed-off-by: Lukas Reschke <lukas@statuscode.ch>
