I. PRODUCT
|
|
|
|
Publisure Hybrid mail is a highly efficient and cost effective alternative to traditional methods of producing and posting correspondence within an organization.
|
|
The Publisure system can either be used for centralized, internal production within your existing facilities or alternatively, it can be implemented as a fully outsourced solution.
|
|
|
|
Note that this advisory is based on a version 2.1.2 which is a legacy version since a newer one was released.
|
|
|
|
II. ADVISORY
|
|
|
|
A combination of three different vulnerabilities permits an unauthenticated attacker to gain Administrator access on the server hosting Publisure application.
|
|
|
|
III. VULNERABILITIES DESCRIPTIONS
|
|
|
|
a) The first issue permits to bypass authentication mechanism allowing malicious person to perform query on PHP forms within the /AdminDir folder that should be restricted.
|
|
b) The second weakness is that SQL queries are not well sanitized resulting in multiple SQL injection in "userAccFunctions.php" functions.
|
|
Using this two steps, an attacker can access passwords and/or grant access to user account "user" in order to become "Administrator" (for example).
|
|
|
|
c) Once successfully authenticated as an administrator, he is able to inject PHP backdoor by using "adminCons.php" form.
|
|
This backdoor will then be stored in E:\PUBLISURE\webservice\webpages\AdminDir\Templates\ folder even if removed from "adminCons.php" view (permitting to hide the malicious PHP file).
|
|
|
|
IV. PROOF OF CONCEPT
|
|
|
|
a) Access to AdminDir PHP scripts and database querying is possible whithout authentication (ex: http://192.168.13.37/AdminDir/editUser.php?id=2)
|
|
b) Vulnerable URL example: http://192.168.13.37/AdminDir/editUser.php?id=sqli
|
|
"editUser.php" vulnerable code: $user = getUserDtails($_GET['id']);
|
|
|
|
"userAccFunctions.php" vulnerable code example:
|
|
|
|
function getUserDtails($id) {
|
|
global $db;
|
|
//The reseller_accounts table has been used to store department information since PDQit
|
|
$Q = "SELECT a.username as username,a.contact_firstname,a.contact_lastname,a.email,r.company_name, a.enabled, a.record_id, a.password, a.unique_identifier, a.reseller_id, a.approval, a.resourceEditType, a.docView FROM accounts a, reseller_accounts r WHERE r.record_id = a.reseller_id AND a.record_id = $id";
|
|
$R = $db->query($Q);
|
|
return $R;
|
|
}
|
|
|
|
c) "adminCons.php" form permits to upload leading to RCE and allow attacker to hide malicious PHP code stored within "/AdminDir/Templates" folder (ex: http://192.168.13.37/AdminDir/Templates/tata.php?c=whoami)
|
|
|
|
|
|
V. RECOMMENDATIONS
|
|
|
|
a) Restrict access to administrative (and other) folder when non authenticated.
|
|
b) Prepare SQL query before execution using PDO to escape injections.
|
|
c) Check file type on file upload forms to prevent PHP code upload instead of templates.
|
|
|
