CWE-89 - Improper Neutralization of Special Elements used in an SQL Command (‘SQL Injection’)


Rukovoditel is an open-source project management tool and CRM tool design to support project managers in complex tasks.

The entities_id parameter in access_rules/rules_form page is vulnerable to authenticated SQL injection. The following request would trigger the vulnerability:

POST /crm/index.php?module=access_rules/rules_form&fields_id=1&entities_id=1<SQLINJECTION> HTTP/1.1
Host: [IP]
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:82.0) Gecko/20100101 Firefox/82.0
Accept: text/html, */*; q=0.01
Accept-Language: en-GB,en;q=0.5
Accept-Encoding: gzip, deflate
X-Requested-With: XMLHttpRequest
Origin: http://[IP]
DNT: 1
Connection: close
Referer: http://[IP]/crm/index.php?module=entities/forms&entities_id=24
Cookie: cookie_test=please_accept_for_session; sid=84edp91galu92kc98ja9r4uhto; PHPSESSID=hru4oem2h86lj609i2acmvrnup
Content-Type: application/x-www-form-urlencoded
Content-Length: 173


The above SQL injection exists in the access_rules/rules_form page due to lack of filtering applied on specific parameter. At line 78 of the source we can see that an unsanitized entities_id is used as part of select query.

78 $fields_query = db_query(“select f.*, t.name as tab_name from app_fields f, app_forms_tabs t where f.type not in (“ . fields_types::get_reserverd_types_list() . “) and f.entities_id=’” . $_GET[‘entities_id’] . “’ and f.forms_tabs_id=t.id order b y t.sort_order, t.name, f.sort_order, f.name”);
 79 while($fields = db_fetch_array($fields_query))
 80 {
 81         $choices[$fields['id']] = $fields['name'];
 82 }
 83 ?>

An attacker either needs administrator privileges or they could trigger this vulnerability through cross-site request forgery.
