Re: [PHP-CHECKER] 99 potential SQL injection vulnerabilities

Excuse my ignorance, or currently tired state, but where is the actual
tool located?  I can find the paper OK.

Thanks.

Hi, we are a group of Stanford researchers and we have recently
developed an automated tool for detecting injection vulnerabilities in
PHP. We ran our tool on the following list of software and found 99
potential security vulnerabilites (inspected bug reports attached
below):

         e107 -- v0.7
         myBloggie -- v2.1.3beta
         utopia NewPro -- v1.1.4
         DCP Portal -- v6.1.1
         PHP Webthings -- v1.4 patched

The tool detects unsanitized user input that subsequently flow into
SQL queries. With slight modifications, it can also find potential XSS
vulnerabilities by inspecting strings echo'ed back as HTML output.

Most of which seem remotely exploitable, and we have notified vendors
of confirmed exploits. We decided not to publish exploits for the
interest of web sites that have deployed such software.

More detailed information, including proof of concept exploits (vendor
notified, and since patched), about the tool can be obtained from the
links below.

We'll appreciate any comments and feedbacks regarding the tool and the
results.

Thanks,
Yichen Xie

8 potentially exploitable vulnerabilities

ERROR: ./editnews.php:@main: _POST#g["newsid"]
----------------------------------------------
This error occurs at lines 24-25 in editnews.php. User input
_POST["newsid"] may directly flow into the SQL query below, resulting
in a potentially exploitable SQL injection vulnerability.

ERROR: ./faq.php:@main: _GET#g["catid"]
---------------------------------------
This error occurs at lines 61-62 in faq.php. We believe user input
_GET["catid"] is improperly checked in the following line: the regular
expression seem to only check the existence of a number. It is
probably missing "^" and "$" that ensures "catid" _is_ a number.

ERROR: ./faq.php:@main: _GET#g["question"]
------------------------------------------
Lines 107-108 in faq.php. Similar as above.

ERROR: ./postnews.php:@main: _POST#g["poster"]

query string at line 42.

ERROR: ./templates.php:@main: _POST#g["tempid"]
-----------------------------------------------
Line 33: $tempid is not validated before being passed into the query
string at line 40.

ERROR: ./users.php:@main: _GET#g["userid"]
------------------------------------------
Line 256: $userid is not properly validated: the regular expression
at line 262 checks the existence of a number in $userid. Missing "^"
and "$"?

ERROR: ./users.php:@main: _POST#g["groupid"]
--------------------------------------------
Line 31: $groupid is not validated before being passed into the query
string at line 72.

ERROR: ./users.php:@main: _POST#g["userid"]
