### SSRF PHP functions
|
|
|
|
Some function such as _**file\_get\_contents(), fopen(), file(), md5\_file()** _ accept URLs as input that they will follow making **possible SSRF vulnerabilities** if the use can control the data:
|
|
|
|
```php
|
|
file_get_contents("http://127.0.0.1:8081");
|
|
fopen("http://127.0.0.1:8081", "r");
|
|
file("http://127.0.0.1:8081");
|
|
md5_file("http://127.0.0.1:8081");
|
|
```
|
|
|
|
### CRLF
|
|
|
|
Moreover, in some cases it might be even possible to send arbitrary headers via CRLF "vulnerabilities" in the previous functions:
|
|
|
|
```php
|
|
# The following will create a header called from with value Hi and
|
|
# an extra header "Injected: I HAVE IT"
|
|
ini_set("from", "Hi\r\nInjected: I HAVE IT");
|
|
file_get_contents("http://127.0.0.1:8081");
|
|
|
|
GET / HTTP/1.1
|
|
From: Hi
|
|
Injected: I HAVE IT
|
|
Host: 127.0.0.1:8081
|
|
Connection: close
|
|
|
|
# Any of the previously mentioned functions will send those headers
|
|
```
|
|
|
|
{% hint style="warning" %}
|
|
For more info about that CRLF vuln, check this bug [https://bugs.php.net/bug.php?id=81680\&edit=1](https://bugs.php.net/bug.php?id=81680\&edit=1)
|
|
{% endhint %}
|
|
|
|
Note that these function might have other methods to set arbitrary headers in requests, like:
|
|
|
|
```php
|
|
$url = "";
|
|
|
|
$options = array(
|
|
'http'=>array(
|
|
'method'=>"GET",
|
|
'header'=>"Accept-language: en\r\n" .
|
|
"Cookie: foo=bar\r\n" . // check function.stream-context-create on php.net
|
|
"User-Agent: Mozilla/5.0 (iPad; U; CPU OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B334b Safari/531.21.102011-10-16 20:23:10\r\n" // i.e. An iPad
|
|
)
|
|
);
|
|
|
|
$context = stream_context_create($options);
|
|
$file = file_get_contents($url, false, $context);
|
|
```
